A CAREFUL NAVIGATOR NEVER RELIES ON ONLY ONE METHOD TO OBTAIN POSITION INFORMATION. Never use this product while operating a vehicle. The background map built into this unit is not intended for navigation and its accuracy has not been verified. This map is derived from U.S. government sources which rely on ground and aerial surveys and satellite data. Since there can be inaccuracies in the data used to create the maps and in the map's resolution, plus position inaccuracies in the navigation system, use caution when using this product. CAUTION When showing navigation data to a position (waypoint), this unit will show the shortest, most direct path to the waypoint. It provides navigation data to the waypoint regardless of obstructions. Therefore, the prudent navigator will not only take advantage of all available navigation tools when travelling to a waypoint, but will also visually check to make certain a clear, safe path to the waypoint is always available. The storage temperature for your unit is from -4 degrees to +167 degrees Fahrenheit (-20 to +75 degrees Celsius). Extended storage temperatures higher or lower than specified will cause the liquid crystal display to fail. Neither this type of failure nor its consequences are covered by the warranty. For more information, consult the factory customer service department. All features and specifications subject to change without notice. All screens in this manual are simulated. Many were taken with an IMS SmartMapTM loaded into one of the cartridge slots.

INSIDE BACK COVER HOW TO OBTAIN SERVICE - U.S.A. ONLY ................................................ BACK COVER INTRODUCTION Thank you for purchasing a Lowrance Avionics AirMapTM. With its large LCD screen, easy to use menus, and outstanding performance, we think you'll be happy with your AirMap for many years. No other handheld GPS receiver on the market today has the AirMap's combination of 12 channel receiver, Jeppesen® database with obstacles (U.S. only), ground and hydrographic mapping cartridge capability, and programmable screens in a handheld unit. Like most GPS receivers, your AirMap doesn't have a compass or any other navigation aid built into it. It relies solely on the signals from the satellites to determine its position. Speed, direction of travel, and distance are all calculated from position information. Therefore, in order for it to determine the direction you're travelling, you must be moving, and the faster - the better. This is not to say the unit won't work at walking speeds - it will. But the faster you travel, the easier it is for the unit to determine your direction. GPS works from satellites that transmit information to the world at very high frequencies. One disadvantage to this frequency is that it's "line-ofsight". In other words, the signals don't bounce around like your local radio or television. If you don't have a clear view of the sky, or if you're inside a metal building, the unit probably won't be able to pick up the signals from the satellites. This is common among all GPS receivers. We have found that using this product inside an aircraft is usually sufficiently close to the windows and windshield that it works well. However, the included remote antenna bracket and cable (model PA-2) lets you mount the removable antenna on top of the dash, in case it's required. Another factor that influences the GPS' position and navigation capabilities is called selective availability or SA. This is small errors purposefully injected into the transmitted signal from the satellites. The government does this to degrade the system's accuracy to civilian and foreign users. Even with SA, GPS is the most accurate navigation system ever invented on such a large scale. The Government's accuracy specification is 100 meters horizontally and 150 meters vertically 95% of the time. In other words, the position shown on your AirMap could be up to 100 meters in any direction from your actual position, and the altitude could be plus or minus 150 meters from what's shown on the screen, 95% of the time. One way around the S/A problem is to purchase a DGPS receiver and connect it to your AirMap. A DGPS receiver (commonly called a beacon receiver), picks up correction signals broadcast from ground stations. The 1 AirMap takes these corrections and applies them to the position and altitude screens, giving you much better accuracy. Even with S/A on, and without a DGPS receiver, your AirMap gives you outstanding position and navigation information. Please sit down with the unit and this manual and familiarize yourself with them before using this unit in the "real world". A simulator is built in, which lets you practice with the receiver. INSTALLATION The AirMap operates from six AA batteries or from 6 to 35 volts DC. The cigarette lighter adapter included with your unit plugs into virtually any aircraft's electrical system. The AirMap automatically switches to external power when it's plugged into the unit (provided that the external power has a higher voltage than the batteries.) If, for any reason, the external power fails, the unit will automatically switch to the batteries. The AirMap does not require batteries when external power is in use, however they make a good backup in case of power failure. A rechargeable battery pack, (optional) has a nickle-metal hydride battery and charger built into a pack that's almost identical to the alkaline battery pack that slides onto the bottom of the AirMap. An external antenna kit supplied with the unit allows the removable antenna to be mounted on a suction cup bracket up to four feet away from the GPS receiver. NiMH BATTERY SUCTION CUP AND BRACKET 2 BATTERY INSTALLATION The AirMap requires six AA batteries. We recommend DURACELL® alkaline batteries, but other brands will work. You can use lithium batteries which will last longer than alkaline batteries (but cost more) or rechargeable ni-cad batteries (won't last as long as standard alkalines). Rechargeable alkaline batteries such as RayOVac® Renewals® will also work . Do not use heavy-duty batteries or any battery other than the ones listed above. Do not mix different types of batteries. (For example, don't use both alkaline and ni-cad batteries at the same time.) To install the batteries, first turn the AirMap so that it is facing you. Now grasp the bottom part of the case and push it to the right until it comes completely off the unit. The bottom part of the case holds the batteries. Next, push the battery holder out the bottom of the battery cover as shown below. Install each battery with the negative end (-) against the spring. The positive end (+) of each battery should be firmly against the metal plate. When all six batteries are installed, slide the battery holder into the battery cover. If the battery holder sticks when sliding into the battery cover, apply a thin film of petroleum jelly to the "O" rings on the battery holder. 3 IMPORTANT! There are arrows molded into the bottom of the battery cover and battery holder. Make certain the arrows are properly aligned! Otherwise, the battery holder won't slide all the way into the cover and the battery pack won't slide onto the unit. Slide the battery pack onto the unit and the AirMap is ready for use. EXTERNAL POWER Instead of batteries, the AirMap can operate on 6 to 35 volts DC from an external power source. To use external power, an adapter cable is supplied with your unit that will plug into your vehicle's cigarette lighter. To use this cable, simply plug one end into the AirMap and the other end into the cigarette lighter. A rubber plug is supplied with your AirMap to cover the external power jack on the side of the unit when it's not in use. You can leave the battery pack on when using external power, no damage to the batteries or the unit will occur. However, if you remove the battery pack from the AirMap, we recommend that the battery contact cover be placed onto the battery pack as shown below. This will prevent the battery pack contacts from shorting against metal objects. A separate cover is provided for the bottom of the AirMap. 4 ANTENNA Your AirMap has a removable antenna that folds over the display when the unit is not in use. This prevents damage to the display. To open the antenna, simply lift on an edge and raise it to the desired position. The antenna is a quick release design, simplifying its removal and installation. To remove the antenna, push the antenna to the right (1), while simultaneously moving the antenna up (2), until it clears the AirMap's right side (3). To replace the antenna, reverse the above steps. Make certain to align the antenna with the AirMap until the antenna slides into place to the left by itself. When it does, the antenna has mated with the connector inside the unit and it's ready for use. 1. 2. 3. Remote Antenna Mount The remote antenna kit lets you mount the AirMap's antenna up to four feet away. The suction cup mount can be installed on virtually any flat surface. First press the suction cup into the hole in the bottom of the bracket. Next, remove the antenna from the AirMap and slide the suction cup bracket over the antenna as shown at right. Press the antenna cable 5 over the suction cup bracket and onto the antenna. This locks the bracket onto the bracket with a friction fit. Press the other end of the cable firmly onto the AirMap's left antenna mounting bracket. Moisten the suction cup and press it onto any clean, smooth surface. The unit is now ready for use. MAP CARTRIDGE INSTALLATION The AirMap uses Jeppesen®, IMS SmartMapTM and WorldMapTM, and C-MapTM cartridges, all of which are packaged in a cartridge housing specifically designed for Lowrance mapping products. The IMS SmartMapTM cartridges contain digitized data of over 120,000 bodies of water. Nearly all inland waterways-public and private lakes, rivers, and streams, plus coastal United States waters up to 25 miles out are included. There are also state and U.S. interstate highways and routes, cities and towns. These inland mapping cartridges cover the entire continental United States in 64 highly detailed cartridges. The WorldMapTM cartridges cover all other areas of the world, showing more detail than the background map, but not as much as the SmartMapTM areas. LEI TEX NOR AS TH IMS AME DAT RICAS ABA SE LEI AME DAT RICAS ABA SE IMS AME DAT RICA'S ABA SE 6 The C-Map cartridges cover most of the world with detailed views of coastal and some inland waters. Over 600 cartridges are available. The Jeppesen® database cartridge contains the location of VOR's, NDB's, intersections, and airports. It also has airport information such as runway length and widths, frequencies, fuel availablity, and more. These cartridges can be updated every 28 days. See page 80 for Jeppesen database update information. To install a cartridge into the AirMap, first make certain the unit is turned off. Never install or remove a cartridge with the unit turned on! You can damage your unit if you install or remove a cartridge with the unit turned on. Next, pry the cover off the back of the unit. Place the cartridge into either slot with it's label facing you as shown at the bottom of the previous page. Now slide the cartridge towards the top until it stops. Replace the cover. REMOVING A CARTRIDGE If you have difficulty removing a cartridge, use the back cover as a removal tool. Simply press one side of the cover against the ridge on the cartridge and gently push towards the bottom of the unit. Don't use a corner of the cover - it could damage it. IMPORTANT! If you unplug the Jeppesen cartridge and turn the AirMap on, or if you swap your Jeppesen cartridge for a newer one, all routes are erased! No waypoints will be erased - only routes. Make certain to write down any stored routes before swapping cartridges. 7 YOKE MOUNTING Included with your AirMap is a yoke mounting bracket. It secures to the yoke's shaft with a clamp. Follow the instructions included with the yoke mount to assemble and attach it to your aircraft. The AirMap attaches to the yoke mount with hook and loop material which is already attached to the back of your unit. Simply press the AirMap onto the hook and loop material that's on the yoke mount. Make certain to push the antenna back as far as it will go. It needs to be as parallel to the ground as possible in order to receive signals from the satellites. See the drawings below for a typical installation. When the AirMap is attached to the yoke mounting bracket, it can operate from batteries or the external power cord. To use the external power cord, simply plug one end into the power connector on the right side of the AirMap and the other end into the aircraft's cigarette lighter. 8 KEYBOARD The keyboard has twelve keys. The arrow keys are tied to most of the features, letting you easily move the mapping cursor, navigate through the menus, make selections from menus, and other tasks. PAGES WPT MENU EXIT Z-OUT Z-IN ENT PWR The WPT key lets you create, save, and recall waypoints and routes. The PAGES key switches the unit between the three major displays: windows, navigation, and mapping. To select different features, or to modify functions, press the MENU key. The Z-OUT and Z-IN keys zoom-out and zoomin your view on the mapping screen. The ENT and EXIT keys let you enter or erase selections. The ENT key works the same as the right arrow key for selecting features. In other words, you can use the ENT key instead of the right arrow key to select a menu or enter data. The PWR key turns both the AirMap and its lights on and off. Note: To prevent an accidental power shutdown, you must hold the PWR key down for a few seconds in order to turn the unit off. 9 OPERATION Turning Power On To turn the AirMap on, simply press the PWR key. A screen similar to the one at right appears. The database cartridge's name and expiration date appears at the bottom of this screen. Press the EXIT key to erase it. A warning message appears next, press the EXIT key to erase it, also. MENUS Most of the adjustments and features are found on "menus". Pressing the MENU key lets you view the menus. Different menus items are added or subtracted to the basic list, depending on which mode (mapping, navigation, or windows) the unit is in. This gives you the features that are specific to the mode you are in, but also has items that are used on all modes. To erase the main menu, simply press the EXIT key. Finding Your Position Cold Start When it's turned on for the very first time, the GPS receiver doesn't know where it is, nor what the local time or date is. If you tell it your position, time, and date, the unit will take less time to lock-on to the satellites and give you a fix or position. However, if you don't want to push buttons at this time, that's fine. The AirMap will lock onto the satellites and give you a position without any input from you. This is called a "cold-start". It simply means that the unit is searching without your help for the satellites that are in orbit. A cold-start can take up to 5 minutes to acquire enough satellite data to determine your position, although it typically takes less time than that. Once the GPS receiver locks on to the satellites and finds your position, it stores the satellite data in its memory. The next time you use the unit, it should take less time to lock on. 10 Once the AirMap locks on to the satellites and finds your position, it stores the satellite data in its memory. The next time you use the unit, it should take much less time to lock on. To use your AirMap, first take it outside, away from hangers and buildings. You need a clear view of the sky. Open the antenna and adjust it so that it is parallel with the ground. Press the PWR key. Read the message on the screen, then press the EXIT key to erase the message. A screen similar to the one at right appears. This is Map 3. Your present position is shown as a cross surrounded by a diamond. As you wait for the AirMap to find your position, you'll see numbers flashing on the display. Anytime you see flashing numbers, it means the AirMap does not have a position! Do not rely on any data that is flashing! When the numbers stop flashing, the unit has locked on to the satellites and the position is good. That's all you have to do to find your position. The time display may not be correct when the cold start method is used. See the manual initialization section for details on changing the time. Finding Your Position Initialization A cold-start as described above can take up to 5 minutes to find your position. There is another method to initialize the AirMap that may let it acquire the satellites faster. Manually entering your position, local time and date will help the GPS receiver determine which satellites are available and lock on to them faster. There are two ways to input your position. You can locate your position on the receiver's map or enter your latitude and longitude. Remember, once the receiver finds its position, it stores the position into memory. The receiver won't have to initialized the next time you it on. Enter by Map To show the receiver your approximate location on its map, first press the MENU key, then the up or down arrow keys until the "GPS SETUP" menu is highlighted as shown at right. Now press the right arrow key. The screen shown at the top of the next page appears. 11 Using the down arrow key, highlight the "Initialize GPS Receiver" menu, then press the right arrow key. The screen shown below appears next. This is the GPS initialization screen. The position, altitude, time, and date the GPS receiver is currently using to find the satellites is shown at the bottom of this screen. Changing these values to your local position and time will speed the position lock. To change the position, highlight the "EDIT LAT/ LON label, then press the right arrow key. A screen similar to the one at right appears. With the "INPUT FROM MAP" label highlighted, press the right arrow key. The screen below appears. The mapping screen appears with two lines that intersect at the center. These lines are the cursor. Using the arrow keys, move the cursor to your present position. You can use the Z-IN and Z-OUT keys to zoom in or out to find your area on the map. Once you have the cursor close to your location, simply press the ENT key. The unit returns to the GPS SETUP menu with your local latitude and longitude showing in the box at the bottom of the screen. 12 Enter Manually To change the position by manually entering the latitude and longitude, press the MENU key, then highlight the "GPS SETUP" label and press the right arrow key. Now press right arrow key again while the "EDIT LAT/LON" box is highlighted. The screen shown at right appears. Highlight the "INPUT MANUALLY" label and press the right arrow key. The screen shown below appears. If your latitude is south, press the up or down arrow key to change it. If it is north, press the right arrow key to highlight the first number in the latitude. Now press the up arrow key to increase the number or the down arrow key to decrease it. Once the first number in the latitude is set, press the right arrow key once to move to the next number in the latitude. Keep pressing the arrow keys until the latitude and longitude are set to your local position. (Note: This position does not have to be very accurate. If you can get it within one degree of your actual position, that will be fine.) When it's set, press the ENT key. The AirMap accepts your entry and returns to the GPS setup menu. Now change the local time and date if they're incorrect on this screen by highlighting the appropriate label and pressing the right arrow key. (Don't worry about altitude.) When everything is acceptable, press the EXIT key to return to a mode screen. The AirMap will instantly use the data you entered to find the satellites in the sky. (The unit knows which satellites will be available at the position, date, and time you entered. Therefore, it will only look for those satellites, making the search time much shorter than a cold start which looks for all of the satellites until it finds three.) Once the AirMap finds and locks on to three satellites, it stops flashing the numbers on the display. (Note: Altitude will still flash until the unit locks on to the fourth satellite. It takes four satellites to determine altitude.) 13 IMPORTANT! If the data shown in digital numbers on any screen is flashing, it means that data is invalid. DO NOT RELY ON ANY NUMBERS THAT ARE FLASHING! Usually, this happens when the GPS receiver has lost its lock on the satellites. The data that is flashing was the last known when the unit lost its navigational capability. DO NOT NAVIGATE WITH THIS UNIT UNTIL THE DATA STOPS FLASHING! POSITION/NAVIGATION DISPLAYS The AirMap has navigation, mapping, and windows group modes. These screens were designed to show data that is used most often. Many of the navigation, mapping, and windows screens can be customized to show data other than the ones chosen by the factory. See the Reprogram Groups section for more details. The three default displays are shown below. To change displays, simply press the PAGES key. A screen similar to the one at right appears. Now press the up or down arrow keys to change modes. (The windows display is shown as "Groups". For example, Group A is the first windows group on the PAGES menu.) Press the right arrow key to see more screens on each mode. When the desired screen appears, press the EXIT key to clear the menu. NAVIGATION (Nav 1) MAPPING (Map 1) WINDOWS (Group A) Note: For a list of abbreviations used on the displays, see the back of this manual. 14 Navigation Screens There are two navigation screens. Nav screen number one shows a graphical view of your trip, the other screen shows all navigation details in large digital numbers. Nav Screen #1 This screen is dominated by a compass rose. Your track (direction of travel) is indicated by an arrow pointing down toward the compass rose at the top center of the screen. Track is also shown in the upper right corner of the display under the "TRK" label. In the example screen shown at right, the track is 7°. The line extending behind the arrow in the center shows your track history. Your speed over ground or Ground Speed is shown at the bottom of this screen. In this example, the ground speed is 140 knots. The screen looks like this when you're not navigating to a waypoint. (See page 58 for information on waypoint navigation.) If you navigate to a waypoint, the screen looks like the one below. The bearing to the destination waypoint is shown in the upper left corner of the screen. Bearing is also shown by the large arrow pointing up to the compass. The numbers on either side of the center arrow show the cross track error range. In other words, (using the screen at right as an example) if the arrow crosses the dark band on either side, you are one mile to the left or right of the desired course. A circle depicting your destination appears on the screen as you approach the waypoint, as shown here. The digital boxes at the bottom of the screen show (from left to right) your distance to go to the destination (DIS), estimated time en route (ETE), ground speed (GS), and course (CRS). Course (CRS) is the bearing from your starting location to your destination. (Remember, 15 course has nothing to do with your present position, except for your starting location.) It's shown as a dotted line on the NAV 1 display. This is shown as a reminder so that if you deviate from your original course, you can easily return to it. (A "course" is a proposed path over the ground. A "track" is your actual path over ground.) All of the digital boxes on this screen are programmable. See the "Programming" section for more information. Nav Screen #2 The navigation screen shows navigation information in large digital numbers. To view this screen, press the PAGES key, then press the up arrow key until the black box surrounds the "NAV 1" label. Now press the right arrow key. A screen similar to the one below appears. Press the EXIT key to erase the menu. This screen is composed of eight digital display boxes, including track (TRK), and ground speed (GS). The destination shows in the upper left corner. Other boxes show navigation data when a waypoint is recalled, including bearing to the waypoint (BRG), distance to waypoint (DIS), and estimated time en route (ETE). The CDI is a course deviation indicator, showing your distance to the left or right of the desired course. You can reprogram all of the digital boxes on the NAV 2 screen. See the "Programming" section for more information. COURSE DEVIATION INDICATOR (CDI) The CDI shows your distance to the left or right of the desired course to a waypoint. (In order to use the CDI, you must first recall a waypoint or route. See the Navigation section for more details.) The arrow in the center of the box shows the direction to the destination. For example, if you're travelling straight towards the waypoint, the arrow points straight up. If you turn to the right, the arrow points to the left, showing that the destination is to your left. 16 The smaller arrows pointing down on each side show the CDI's range. The default is 1/10 mile. The small vertical bar shows the distance off course and represents the course line. If the bar moves to the right, then you are to the left of the desired course line, and vice-versa. The CDI indicator shown above shows that we are about .02 miles to the left of the desired course. (With the CDI range of .10 miles, each vertical dotted line represents .02 mile.) You can adjust the CDI's range through the "Alarms/CDI" menu. Using the CDI with a mapping screen helps you visualize your position in relation to the course. The screen below left shows that we are on course. The CDI arrow is pointing straight ahead and no off-course bar is showing. Looking at the screen on the right, however, you can see that we are off course to the right. In fact, we are so far off course that we exceeded the range of the CDI. The vertical bar has gone off the scale on the left side of the CDI. A small arrow points to the left, showing the direction to the desired course line. The CDI gives you a quick, easy to read visual indicator of your relationship between your direction of travel and the desired direction. Mapping The AirMap has a ground map of the world built inside. This map has the majority of its detail in far southern Canada, the continental United States and Hawaiian islands, northern Mexico, the Bahamas, and Bermuda. The background map shows when the AirMap is first turned on, with or without a map cartridge. With the Jeppesen® cartridge plugged in, a complete aviation database is activated. Airports, NDBs, VORs, and other airspace information (including obstructions) are overlaid onto the ground map. 17 MAP 1 MAP 2 MAP 3 There are three different mapping screens available. Map screen number 3 shows by default, as shown at right. Your current position displays at the center of the screen by a cross surrounded by a flashing diamond. To view the other mapping screens, press the PAGES key. Press the up or down arrow key to highlight the "MAP 1" label. Now press the right or left arrow key to select a different mapping screen. Press the EXIT key to erase the pages menu. Maps 2 and 3 (as shown above) have navigation data displayed using digital numbers. The digital displays on map 3 can be rearranged or changed to other displays. See the "Reprogram Boxes" section for more information. As you move, the map slides past your present position, which always remains at the center of the screen. The line extending from your position shows the path you've taken. Use the Z-OUT and Z-IN keys to enlarge or reduce the mapping area. If you have an IMS SmartMapTM cartridge installed, it's detail typically begins showing when you zoom in to the 10 mile range. JeppesenTM data shows at all zoom ranges, however, Lowrance® has a unique method of displaying this data. If you were to turn on all airports, VORs, NDBs, and controlled airspaces at the same time without filtering the data, the map screen would become so cluttered that it would be useless. The AirMap turns off virtually all aviation data at large ranges, selectively turning on more data as you zoom in closer to your present position or cursor location. See the two screens at the top of the next page. The first one's range is 150 NM and shows little aviation data. The second screen is zoomed in to the 30 NM range and now shows much more detail around the present position. 18 AUTOZOOM Generally, when you travel using a mapping receiver like the AirMap, you spend some amount of time zooming in and out, looking at detail or the whole route between the start and destination. (Note: The autozoom feature does not work with C-Map cartridges.) The AirMap has an autozoom feature that eliminates much of the button pushing that competitive units force you to make. It works in conjunction with the navigation feature. First you must recall a waypoint. (See the waypoint section for more information on navigating to a waypoint.) When you turn the autozoom mode on, the AirMap zooms in on your present position. As you travel towards the destination (recalled waypoint), the AirMap begins zooming out, showing more of your course to the waypoint. After you cross the halfway point to your destination, the AirMap zooms in closer, one zoom range at a time, keeping the destination on the screen. Nearly every time it zooms in, you can see more detail. This is a benefit for two reasons. Number one, you want to see more detail as you get closer to the destination, especially if you've never been there before. Two, it takes a load (small, perhaps, but still another thing to keep track of) while you're occupied with other details. The screens at the top of the next page show a slice of the progression of a trip on an area lake. Screen number one is the start and is on the 1 mile range. Intermediate stages progressively zoom out, until you're at the midway point. The AirMap then begins zooming in as you get closer to the destination. 19 To use the autozoom feature, first set the AirMap up to navigate to a waypoint. (See the Navigation section for more details.) Next, simply press the MENU key, then use the up or down arrow keys to highlight the "AUTOZOOM OFF/ON" menu. Press the right arrow key to turn it on, the left to turn it off. Map Cursor Pressing an arrow key while a map is on shows two dotted lines that intersect at your present position. These dotted lines are called a "cursor" and have a variety of uses. You can move the cursor around the display by pressing the arrow keys in the direction you want it to move. This lets you view different areas of a map, away from your present position. When it's turned on, the zoom-in and zoom-out keys work from the cursor's position - not the present position, so you can zoom in on any detail, anywhere while navigating. CURSOR OFF 20 CURSOR ON The latitude/longitude of the cursor shows in the box at the top of the screen whenever the cursor is activated. The map cursor is also used to place and erase icons and waypoints. MAP SYMBOLS Airports, VORs, NDBs, and Intersections All airports are shown as a square with its identifier beneath it. Larger airports are shown the same way until you zoom in closer, then their runways become visible. Zoom in farther, and the runway numbers also appear. VOR's are shown as a circle with a dot inside, while NDB's have a triangle. Intersections are depicted as an "X". AIRPORT WITH AIRPORT WITH SMALL RUNWAY(S) LARGE RUNWAY(S) VOR NDB INTERSECTION Obstructions Your Airmap has obstruction capability. The database cartridge installed in your unit lets you see ground obstructions on the map display such as radio and television towers. This information is included in the Jeppesen® cartridge, so you don't need two cartridges for aviation data. The obstruction portion of the database cartridge covers all of the continental United States, Alaska, and parts of Canada, Mexico, and Bahamas. On the screen shown at right, four obstructions are shown. Three different symbols are used to show them, depending on their height. They are: 21 SMALL - 205 to 499 feet MEDIUM - 500 to 999 feet LARGE - 1000 feet and above The elevation shows beneath the symbol. If a line is beneath the elevation, then the height is AGL, or above ground level. If no line shows beneath the height, then it is MSL or above mean sea level. For example, this obstruction is 315 feet AGL: This obstructions is 315 feet MSL: Typically, you'll need to zoom in to a range of 40 miles to see the large obstruction symbols, and smaller ranges to see the larger obstruction's height and smaller obstructions. To view smaller obstruction's height, you may need to zoom in to the 5 mile range. You can turn the obstructions on or off and switch from AGL to MSL by highlighting the "OBSTRUCTIONS" label on the "Air Map Options" menu, then pressing the right arrow key. The obstruction menu appears as shown at right. The AirMap defaults are: obstructions from 205 to 499 feet (shown as 200-500 on the menu) off and obstructions 500 feet and above on. AGL defaults on, also. You can change any of these by highlighting the desired menu, then pressing the left or right arrow keys. 22 Airspace The AirMap can show the following airspaces: Class B and C airspace, control zones, control areas (CTA), Terminal Control Areas (TMA), prohibited, restricted, MOA's (including training, danger, and caution areas), and alert areas. In this example, the Class C airspace surrounding Tulsa International airport (TUL) is clearly visible as two dark circles. The control zone airspace around Richard Jones (Riverside) airport (RVS) is shown in gray. This screen shows the Eureka MOA east of Wichita, Kansas on the 100 nautical mile range. The airspace defaults for the AirMap are as follows: Class B, C, D, Prohibited, Restricted, and MOA's are on. All other airspaces default off. An airspace alarm can be set that will warn you of any of the above airspaces are within a preset radius of your position. Another airspace alarm will "look-ahead" and tell you how soon you will cross into an airspace. See the alarms section fro more information. Airspace Information The AirMap lets you identify an airspace without physically entering it by using the cursor. To do this, press any arrow key while a map is showing. In this example, we're using Map 1. The cursor appears. Now move the cursor to the desired airspace as shown at right. (Note: You may have to zoom-in and/or zoom-out to view the airspace.) 23 With the cursor moved to the airspace, press the MENU key. A screen similar to the one at right appears. Now highlight the "Airspace Info" label and press the right arrow key. A message screen appears as shown below. This is the information for the airspace that the cursor is resting on. To view information about another airspace, simply move the cursor to that airspace and repeat these steps. To erase this screen, simply press the EXIT key. Air Map Options You can select the aviation symbols and airspaces that you want displayed on the screen. To do this, first press the MENU key, then press the up or down arrow keys until the black box is on the "AIR MAP OPTIONS" label. Press the right arrow key to select it. A screen similar to the one at right appears. Use the up and down arrow keys to move the box to the desired symbol, then press the right arrow key to turn it on or the left arrow key to turn it off. Note: You can't turn off restricted or prohibited airspaces. To change the airspace selections, press the down arrow key until the "Select Airspaces" label is highlighted, then press the right arrow key. The screen shown at right appears. 24 Again, use the up and down arrow keys to move the box to the desired airspace that you wish to change, then press the right arrow key to turn it on or the left arrow key to turn it off. Press the EXIT key when you're finished with this menu page. The AirMap returns to the AirMap Options menu. Map Orientation Normally, the AirMap shows the map with north always at the top of the screen. This is the way most maps and charts are printed on paper. This is fine if you're always travelling due north. What you see to your left corresponds to the left side of the map, to your right is shown on the right side of the map, and so on. However, if you travel any other direction, the map doesn't line up with your view of the world. To correct this problem, the AirMap has a trackup mode that rotates the map as you turn. Thus, what you see on the left side of the screen should always be to your left, and so on. It also has a course-up mode that keeps the map at the same orientation as your initial bearing to the waypoint. NORTH-UP TRACK-UP 25 In the example at the bottom of the previous page, we're travelling with a track of 200°. In the north-up view, the present position indicator appears to move towards the lower left corner of the screen. In the track-up view, the present position moves straight towards the top of the display. A "N" shows to help you see which direction is north when the track-up mode is on. Remember, the track-up mode, the screen rotates as you change direction. It always keeps your direction of travel (track) heading towards the top of the screen. NORTH-UP COURSE-UP In the course-up mode, the screen is locked into your original bearing to the recalled waypoint, (user waypoint, airport, NDB, VOR, or cursor location) regardless of your track. (Note: the track-up and course-up modes do not work when the unit is zoomed-in on a C-Map cartridge.) To select the desired mode, press the up or down arrow keys to move the black box to the "UP ORIENTATION", then press the right arrow key to select it. Press the EXIT key to return to the mapping screen. EARTH MAP OPTIONS The earth map consists of the built-in background map of the world, plus any cartridge that is attached to the AirMap. To change the Earth map options, first press the MENU key, then press the up or down arrow keys until the Earth Map label appears. Highlight the label, then press the right arrow key to select it. The screen shown at right appears. 26 Text Labels Use this menu to turn all names on the map (such as Lake Tahoe or Mississippi River) off or on. The default is "on". Press the left arrow key to turn them off. Map Boundaries If you have a IMS SmartMapTM or a C-MAPTM cartridge plugged into the back of the AirMap, this feature will show the boundaries of the cartridge on the map. This lets you know the exact area covered by your cartridge. The example at the top of the next page shows the boundaries of the Oklahoma - East IMS SmartMap cartridge. The default for this feature is on. Press the left arrow key on the "MAP BOUNDS" label to turn them off. Move Map Center In normal operation, the present position indicator stays in the center of the screen and the map moves past it as you travel. To move the present position indicator to a different part of the screen, highlight the "Move Map Center" label on the "Earth Map Options" menu and press the right arrow key. The unit returns to the mapping screen with the message "Set Map Center" flashing at the bottom of the screen. Use the arrow keys to move the present position indicator to the desired location on the screen, then press the EXIT key. This locks the present position indicator in this location. The above examples show the present position in the center of the screen, then moving the present position down and to the left. This shows more of the lake. 27 Earth Map On/Off You can turn the earth map completely off, clearing the screen of all ground detail (including IMS SmartMap cartridge detail). To do this, highlight the "EARTH MAP OFF/ON" label and press the left arrow key. Icons On/Off The AirMap has symbols that you can place at any location. These symbols can be turned off, if desired. To do so, move the black box to the "ICONS OFF/ON" label and press the left arrow key. See the "ICONS" section in this manual for more information on the icon symbols. Note: This doesn't erase the icons, it merely "hides" them. Detail Cartridge The AirMap has two cartridge slots in its back. Either one can hold a IMS SmartMap or C-MAP cartridge. The unit can only show detail from one type of cartridge at a time. In other words, you can't show detail from an IMS SmartMap and a C-MAP cartridge at the same time. You must select one or the other. The "Detail Cartridge" menu lets you select the type of cartridge to display. When you install a mapping cartridge, and wish to use it, switch the "Detail Cartridge" to the desired selection on this menu. To do this, simply highlight the menu, then press the left or right arrow keys to select the proper cartridge type. C-MAP OPTIONS If you are using this receiver with a C-Map cartridge, a new menu appears on the main menu list. This is the "C-Map Options" menu. Highlight this menu item and press the right arrow key. The screen at right appears. These menu items let you turn the depth lines, restriction areas, coastal features, and marine navigation aids off or on. Highlight the desired feature, then press the right or left arrow key to change them. Press the EXIT key when you're finished. 28 Fill With Gray When the AirMap is first turned on, all water is filled with gray to distinguish it from land, which is clear. (See below) To make the land fill with gray and water remain clear, press the down arrow key until the "Fill With Gray" menu is highlighted, then press the left arrow key. Press the EXIT key to return to the mapping screen. FILL WITH GRAY - WATER FILL WITH GRAY - LAND Normally, you'll want to fill water with gray when you're using the GPS receiver on land and fill land with gray when you're using it on the water. PLOTTER OPTIONS Plot Trail The line extending from your present position is called a plot trail. This unit lets you customize the plot trail with the following menu items. All of the items on the Plotter Options menu affect the plot trail. Plot Trail Flashing Since there can be many lines on the mapping display, it's helpful at to make the plot trail flash. This usually makes it easier to see. The default for plot trail flashing is on. To turn it off, highlight the "Plot Trail Flashing" label on the "Plotter Options" menu, then press the left arrow key. Press the EXIT key to return to the map. Repeat the above steps to turn the flashing on. 29 Set Visible Plot Trails The plot trail can be turned off, if desired. To turn it off, press the up or down arrow key until the "Set Visible Plot Trails" menu is highlighted. Now press the right arrow key. The screen at right appears. Use the up or down arrow keys to select the desired plot trail, then press the left or right arrow key. Press the EXIT key to return to the Plotter Options menu. Clear Current Plot Trail To erase the plot trail extending from your present position, highlight the "Clear Current Plot Trail" menu, then press the right arrow key. A message box appears, asking you if you really want to erase the plot trail. Follow the directions on this message box. The unit returns to the mapping screen after the message box clears. Save Current Plot Trail You can save up to two plot trails in memory. The receiver saves these trails even if power is removed from the unit. To save your current plot trail, highlight the "Save Current Plot Trail" menu using the arrow keys. Now press the right arrow key. The screen at right appears. You can save the plot trail as #1 or #2. Highlight the desired plot trail number, then press the right arrow key. A message box appears asking you if you really want to save the trail. Follow the instructions in this box. The mapping screen appears after the message box clears. Your plot trail is now stored in memory. To view your saved plot trail, see the "Set Visible Plot Trails" section. Set Plotter Update Criteria The plotter places a dot on your trail as you move. It determines when to place a dot depending on two things: time and distance. By default, it places a dot every three seconds. 30 To change the update, highlight the "Set Plotter Update Criteria" menu item, then press the right arrow key. The screen at right appears. To change the update to distance, press the right arrow key while the "Plot Update Criteria" menu is highlighted. Change the plotter update time by highlighting the "Plot Update Rate" menu, then press the left or right arrow keys until the desired time appears. The distance update is changed in the same manner. Highlight the "Update Distance" menu, then press the left or right arrow keys until the desired distance appears. When you have everything on this menu adjusted to the desired settings, press the EXIT key to erase the menu. ICONS The AirMap has fifteen symbols or "icons" available. These icons can be placed anywhere on the mapping screens. These can be used to mark fishing spots, boat ramps, rest stops, airports, or whatever. You can place an icon at your present position, or at the cursor location. Place Icon - Present Position To place an icon at your present position, simply press the ENT key. The screen shown at right appears. Use the arrow keys to highlight the desired icon. Now press the ENT key. The mapping screen appears with the icon you selected placed at your position when you first pressed the ENT key, not your present position. MAP - BEFORE PLACING ICON 31 MAP - AFTER PLACING ICON Place Icon - Cursor Location To place an icon at cursor's location, first use the arrow keys to move the cursor to the position that you want to place the icon. Next, press the ENT key. Now select the desired icon using the arrow keys. When it's selected, press the ENT key. The mapping screen reappears with the icon at the cursor's location. Press the EXIT key to erase the cursor. MOVE CURSOR TO LOCATION PRESS ENT, SELECT ICON, PRESS ENT PRESS EXIT TO ERASE CURSOR Erase Icons To erase an icon from the screen, first press the MENU key, then select the "Icon Options" menu as shown at right. There are three methods used to erase icons from the screen. You can delete all of the icons, regardless of their position on the display, delete all of the icons of a certain type, or selectively erase individual icons. You can also simply turn the icons off by highlighting the "ICON SYMBOLS" menu, then pressing the left arrow key. This doesn't erase the icons, it simply "hides" them from the map. To erase all of the icons, highlight the "Delete All Icons" menu, then press the right arrow key. A message appears, asking you if you want to delete all icons. Press the left arrow key to erase them. The unit returns to the mapping screen with all icons deleted. To remove only icons of a certain type, highlight the "Delete Icons By Type" label. Press the right arrow key. The icon selection menu appears. Use the arrow keys to highlight the icon style that you wish to erase. Press the ENT key when you're ready to erase the icons. A message appears, asking you if you want to delete the icons of that type. Press the left arrow key to erase them. The unit returns to the mapping screen with all icons of the type you selected erased. 32 To remove only certain icons, highlight the "Delete Icons From Map" label. Press the right arrow key. The unit returns to the mapping screen with the cursor centered on your present position. Use the arrow keys to move the cursor to the icon on the map that you wish to erase. Press the ENT key when you're ready to erase the icon. A message appears, asking you if you want to delete that icon. Press the left arrow key to erase it. If you wish to delete another icon, move the cursor over it and press the ENT key. When you're finished, press the EXIT key to erase the cursor. WINDOWS The windows feature gives you over 45 different displays that you can arrange in 15 different groups. This lets you customize the unit to your own situations. To use the windows feature, press the PAGES key, then press the up or down arrow keys to highlight the "GROUP A" label as shown at right. The windows have 15 different pre-programmed groups: A through N. Group "A" is visible in the background when you switch to the windows groups. To view each group, simply press the right or left arrow key while the mode menu is showing. Each group shows in the background as you press the arrow keys. When you see the group you want to use, press the EXIT key to erase the mode menu. REPROGRAM WINDOWS GROUPS All of the 15 windows groups can be customized. The changes you make to the groups will remain in memory, even if all power is removed from the unit. You can, however, return the groups to the factory settings from the "Preset Groups" menu. To customize a group, first switch to a windows group. It doesn't have to be the group you want to customize. Next, press the MENU key, then highlight the "Reprogram Groups" menu and press the right arrow key. A screen similar to the one shown at right appears. The group selection menu is at the top of the screen. Using the left or right arrow keys, choose the group you want to change. When 33 REPROGRAMMING A GROUP 1. 2. 3. SELECTED "REPROGRAM GROUPS" FROM MAIN MENU. PRESSED THE UP ARROW KEY TO REPROGRAM GROUP "F". THE WINDOW SELECTION SCREEN APPEARS. PRESS THE RIGHT ARROW KEY UNTIL THE DESIRED WINDOW APPEARS. THIS IS THE FIRST WINDOW THAT WE WANT TO USE. PRESS THE UP ARROW KEY TO SELECT IT. 4. 5. 6. AFTER TWO MESSAGES APPEAR AND ERASE THEMSELVES, YOU'RE RETURNED TO THE WINDOW SELECTION MENU. REPEAT STEPS 2 AND 3. WE CHOSE THIS WINDOW AS THE SECOND ONE FOR THIS GROUP. REPEAT STEPS 2 AND 3 AGAIN. THE LAST WINDOW CHOSEN. 7. 8. See the back of this manual for a complete listing of all window groups. THIS MESSAGE APPEARS AFTER THE LAST WINDOW IS SELECTED FOR THE GROUP. IT AUTOMATICALLY ERASES. THE FINISHED GROUP. THIS IS THE NEW GROUP "F". 34 the desired group letter is showing in the box (and in the background), press the up arrow key to change it. A screen similar to the one at right appears. The first window appears on this screen. A description of the window appears in a box on this screen, also. If you wish to use it, simply press the up arrow key. The unit flashes a message on the screen, telling you it's adding the new window to the group. When it's finished, it returns to the window selection menu. You can now press the right or left arrow keys to select the next window in the group. When you're filled the group with windows, the unit automatically saves your reprogrammed group. You can reprogram all groups, if desired. If you're finished selecting windows before filling the group with windows, press the EXIT key. If you fill the group with windows, the unit will automatically leave the menu after the last window is selected. To return all groups to the factory defaults, see the "Preset Groups" in the "System Setup" section. Note: The digital boxes on the navigation and map #3 screens can also be reprogrammed. Follow the same steps show above to program the navigation and map screens. (The menu label is called "Reprogram Boxes" for the navigation and map screens.) Special Windows Although most of the windows used in the AirMap are self-explanatory, there are several windows that have special features or can be used in unique ways. The following section describes these windows. Satellite Information Screen (Group O) This screen shows technical information about the status of the GPS receiver. The receiver has five channels. Data for each channel is shown on the display. The channels are numbered one through 5 on the left side of the screen. Every satellite in the constellation has a number assigned to it, called the PRN. This number shows to the right of the channel. The TRK column shows a "T" if the channel is track35 ing the satellite, or a "S" if the receiver is searching for it. ELV is the elevation of the satellite above the horizon; AZM is the azimuth, or direction of the satellite from your location. SNR is the signal-to-noise ratio. The higher the SNR, the better. If you look at row one in the satellite info screen at right, channel 1 is tracking satellite number 28. The satellite's elevation is 25 degrees above the horizon and it's azimuth is 44 degrees. It's SNR is 44, which is good. The FIX numbers in the lower left corner of the screen show the quality of fix. If the FIX is 9, then it's the best you can get. A FIX of 1 is the worst. The DOPS display beneath the fix quality show you the "Dilution of Precision" for the horizontal (HDOP), geometric (GDOP), position (PDOP), time (TDOP), and vertical (VDOP). The GDOP is a combination of HDOP, VDOP , and TDOP. The smaller the DOP's value, the better. The receiver selects satellites based on the GDOP value, therefore, it always tries to use satellites that have good DOP values. These depend on the azimuth and elevation of the satellite, and any ground based obstructions. The circular plot in the lower right corner of the screen shows a graphical view of the satellites that are in view. Each satellite is shown on the circular chart relative to your position. The point in the center of the chart is directly overhead. The small inner ring represents 45° above the horizon and the large ring represents the horizon. North is at the top of the screen. You can use this to see which satellites are obstructed by obstacles in your immediate area if you hold the unit facing north. The GPS receiver is tracking satellites that are surrounded by a black box. If the satellite number is not surrounded by a box, then the receiver hasn't locked onto that satellite and it isn't being used to solve the position. 36 Dual Mapping The windows feature gives you the capability to have more than one map on the display at one time. For example, group "A" shown at right has two half-screen maps, side-by-side. Both of these maps are completely independent of each other. In other words, you can zoom in or out, set options, and other functions on one map, without affecting the other. When you press the MENU, ZOOM IN or OUT, or ENT keys, a message appears asking you which display you want to affect. On the screen shown at right, the menu key was pressed. The unit wants to know which map you want to change. Press the left arrow key for the left map, the right arrow key for the right map. The main menu then appears. CLOCK Whenever a clock is showing on a display, new items appear in the list when you press the MENU key. These items let you set the clock's time, set alarms, and change the unit of measure. The clock and timers can be used on windows, mapping, or the navigation mode. 37 Clock Set If the time shown on the clock display is not your local time, change it using the "Clock Set" function. To do this, press the MENU key, then press the up or down arrow keys until the "Clock Set" label is highlighted. Press the right arrow key. The screen at right appears. Using the right and left arrow keys, highlight the first number in the time that you want to change. Now press the up or down arrow keys until the desired number shows. Continue until the time shown in the display is correct, then press the ENT key. The unit returns to the navigation, mapping, or windows display with the new time showing. Clock Hours Normally, the time shows in the twelve hour format (a.m./P.M..). To change it to 24-hour format, press the MENU key, then select the "CLK HRS" label. Now press the right arrow key to change it to 24, then press the EXIT key. Clock Alarm You can set an alarm (that works just like an alarm clock), by using the "Clock Alarm" menu. To set this alarm, press the MENU key, then highlight the "Clk Alm Set" label. Press the right arrow key. A screen similar to the one at right appears. Using the right and left arrow keys, move the black box to the first number in the time that you want to set. Now press the up or down arrow keys until the desired number shows. Continue until the time shown in the display is correct, then press the ENT key. The unit returns to the navigation, mapping, or windows display. To turn the alarm on, press the MENU key, then select the "CLK ALM" menu. Press the right arrow key. The alarm is now activated. When the alarm goes off, an audible tone sounds along with a flashing message on the screen. Press the EXIT key to turn the alarm off. Note: The AirMap must be on in order for the alarms to work. In other 38 words, if you set the alarm to go off at 7:00 a.m., then the AirMap will have to be on at 7:00 a.m., also. TIMERS The AirMap has two timers built in. One is a countdown timer and the other is a count-up timer. The countdown timer counts down from the time you put in to zero. The count-up timer starts at zero and counts up to the time you entered. To set either timer, first switch to a screen that is showing the timer that you want to use. Next, press the MENU key, then highlight the desired timer set menu. In this example, we're setting the countdown timer. Now press the right arrow key. A screen similar to the one below appears. Using the right and left arrow keys, move the black box to the first number in the time that you want to set. (The time is in hours, minutes, and seconds) Now press the up or down arrow keys until the desired number shows. Continue until the time shown in the display is correct, then press the ENT key. In this example, the down timer is set for 10 minutes. The unit returns to the navigation, mapping, or windows display. To start the timer, press the MENU key, then move the black box to the "Dn Timer STOP/ GO" label. Press the right arrow key to start the timer. The timer continues counting until you stop it. If you turn the up timer's alarm on (press the right arrow key when the black box is on the (Up ALM...Off/On label), it will sound a tone when it reaches the time you entered in the up timer set menu. Press the EXIT key to silence the alarm. You can reset either alarm to the time you originally set by pressing the MENU key, then moving the black box to either the "Up Timer Reset" or "DN Timer Reset" label, then press the right arrow key. 39 REPROGRAM BOXES The digital boxes on the MAP 3 and both NAV screens can be reprogrammed. The changes you make to the screen will remain in memory, even if all power is removed from the unit. You can, however, return the boxes to the factory settings from the "Preset Groups" item in the "System Setup" menu. To customize a screen, first switch to the screen that you want to customize. Map 3 is used as the example on the next page. Next, press the MENU key, then press the up or down arrow key until the "Reprogram Boxes" menu is highlighted. Press the right arrow key. The screen shown as number two at the top of the next page appears. The first window appears on this screen. A description of the window appears in a box on this screen, also. If you wish to use it, simply press the up arrow key. The unit flashes a message on the screen, telling you it's adding the new window to the group. When it's finished, it returns to the box selection menu. You can now press the right or left arrow keys to select the next box in the group. When you're filled the group with boxes, the unit will automatically save your reprogrammed group. If you're finished selecting boxes before filling the group, press the EXIT key. If you fill the group with boxes, the unit will automatically leave the menu after the last box is selected. To return the group to its factory default, see the "Preset Groups" in the "System Setup" section. 40 REPROGRAMMING BOXES 1. 2. 3. SELECT "REPROGRAM BOXES" FROM MAIN MENU. THE BOX SELECTION SCREEN APPEARS. PRESS THE RIGHT ARROW KEY UNTIL THE DESIRED BOX APPEARS. THIS IS THE FIRST WINDOW THAT WE WANT TO USE. PRESS THE UP ARROW KEY TO SELECT IT. 4. 5. 6. THE FIRST BOX IS PLACED AT THE TOP. AFTER MESSAGES ERASE THEMSELVES, YOU'RE RETURNED TO THE BOX SELECTION SCREEN SHOWN IN STEP 2. WE CHOSE THIS WINDOW AS THE SECOND ONE FOR THIS GROUP. REPEAT STEPS 2 AND 3 AGAIN. "vOLTS" IS THE LAST BOX CHOSEN FOR THIS SCREEN. 7. 8. See the back of this manual for a complete listing of all box options. THIS MESSAGE APPEARS AFTER THE LAST BOX IS SELECTED . IT AUTOMATICALLY ERASES. THE FINISHED SCREEN. 41 DATABASES Thanks to the Jeppesen database and the AirMap's ability to save locations in memory, (waypoints) you can navigate to virtually any location. The AirMap can store up to 250 waypoints. You can store your present position, the cursor's location, or enter latitude/longitude positions as waypoint locations. The Jeppesen database contains airport, VOR, and NDB locations, plus pertinent airport data such as com frequencies, runway information, and services (fuel availability, repairs, oxygen, etc.) You can also create routes composed of airports, VORs, NDBs, or your own waypoints in any combination. Aviation Database To use the database, first press the WPT key. The screen shown at right appears. This is the User Waypoint screen. You'll use this screen to store and recall your own locations. Now press the up arrow key. This moves the black box to the "TYPE" label at the top of the screen. Pressing the right arrow key repeatedly switches to each of the database screens in the order shown below. AIRPORT VOR NDB INTERSECTION 42 To find a particular airport, VOR, NDB, or intersection, first switch to the appropriate database. In this example, we'll use the airport database. Suppose we're planning a trip to Fort Smith Regional airport in Fort Smith, Arkansas. There are three ways to find this airport in the AirMap's database. You can find it by searching through the airport identifiers (ID), airport name, or city. In this example, we know the airport identifier is FSM, so we'll move the black box to the "ID" label by pressing the down arrow key once. Select the first letter in the identifier by pressing the up or down arrow keys until the letter "F" appears in the "ID" field. When it does, press the right arrow key once. This moves the selector to the second number in the identifier field. Again, press the up or down arrow keys until the letter "S" appears. Finally, press the right arrow key one more time, moving the selector to the last number in the "ID" field, then press up or down arrow keys until the letter "M" appears. The screen should look like the one at right. You can find an airport by using the airport name (name) or city fields the same as the ID field. Simply move the black box to the desired label, then use the arrow keys to select the name. After you've found the airport, press the EXIT key. The screen shown at right appears. At the bottom of the screen is the airport's elevation, which in this case is 469 feet. Beneath this is the airport's position, and at the very bottom of this screen in the distance and bearing from your present position to the airport. 43 Communication Frequencies To view the communication frequencies used at the selected airport, press the down arrow key, move the black box to the "COMM FREQUENCIES" label and press the right arrow key. The screen shown below appears. This is the communication frequencies screen. In this example, all applicable com frequencies for Fort Smith Regional airport are shown. Also, this airport has more frequencies that can be shown on one page. Press the left or right arrow keys to view the rest of the radio information. When you're finished with this screen, press the EXIT key. The AirMap returns to the previous database screen. Runways To view the runway information, press the down arrow key on the airport database screen shown at the top of this page until the black box is on the "RUNWAYS" label, then press the right arrow key. A screen similar to the one at right appears. The "runways" label is highlighted. Press the right arrow key to select it. The screen shown below appears. The active runways available at the time of your database are shown on the left side of the screen. Data for each runway is shown on the right side of the screen. In the example screen shown above, runway 7 - 25 has a hard surface, is 8000 feet long and 150 feet wide. It also has lights which are activated on 118.30 mHz. To view the data for the other runway, press either the right or left arrow key. The screen shown at the top of the next page appears. Now information for runway 1 - 19 is shown on the right side of the screen. 44 If the airport has more than two runways, simply keep pressing the right or left arrow keys until the desired runway appears. When you're finished with this screen, press the EXIT key to return to the airport database screen. Runway Extensions This unit can draw an extension onto a runway to make it easier to line up to the runway on final approach. To use the extension, you must first navigate to an airport. (See the Navigation section for more details.) In this example, we're navigating to Halliburton field in Duncan, Oklahoma. Next, select "Runways/Extensions" from the "Airports" database as shown at right. The screen shown below appears. Now highlight "Runway Extensions" on this menu and press the right arrow key. Use the left or right arrow keys to select the desired runway. In this example, we're using runway 17. Press the ENT key when the desired runway appears. A line is drawn on the screen extending from the airport in line with the selected runway. To turn the extension off, repeat the above steps, but press the EXIT key on the above menu. 45 Services To view the services available at the airport, press the down arrow key on the AIRPORTS main menu shown at the top of the previous page until the black box is on the "SERVICES" label, then press the right arrow key. The screen at right shows. After viewing the information, press the EXIT key to return to the airport database screen. Other Aviation Databases To view VOR, NDB, or intersection data, simply switch to the desired database, then use the arrow keys to view it. They work identically to the airport database. Note: The VOR database as shown at right has a space to the right of the frequency box. If the VOR has DME, the letters "DME" appear in this box. If not, the box is left blank. USER DATABASE The AirMap gives you the capability of creating your own database of locations, called "waypoints". These locations are stored in the "User WPTs" section of the database. You can save your present position, cursor position, or enter a latitude/longitude and save it as a waypoint. Saving Your Present Position as a Waypoint (Quick Save Method) To save your present position, simply press the WPT key twice. The AirMap puts your current position into the first available waypoint number on the list. A message appears on the display telling you the waypoint number it just used. This also momentarily places you in the database menu as shown at right. Anytime a database menu is showing, simply press the WPT key once and the unit will store your present position in the waypoint list. 46
