the basics (or if you already have some GPS experience), you may want to try out some of AirMap's many advanced features. That brings us to Section Four, Land Mode Operation, which also includes its own onepage quick reference. After we introduce the Land Mode menus and submenus, the rest of the section contains AirMap's more advanced command functions. Your AirMap is ready to use right out of the box, but you can fine tune and customize its operation with dozens of options. We describe how to use them in Section 5, System Setup and GPS Setup Options. This section covers both Aviation Mode and Land Mode options. Finally, in Section 6, we go into more detail on one of AirMap's most remarkable capabilities Searching. We'll introduce a couple of search examples in both the Aviation and Land mode sections, but there are so many map and aeronautical items you can search for, we had to give this function its own section in the manual! For example, we mentioned telephone numbers earlier. Your AirMap can function as a virtual Yellow Pages, and well show you how in Section 6. Now, if you're into the fine details, glance over the next segment on specifications to see just how much GPS power you hold in your hand. It's important to us (and our power users), but, if you don't care how many waypoints AirMap can store or how long the batteries last, skip ahead to important information on how AirMap works, on page 5.

Full Map page display option
The aircraft symbol centered in the lower third of the screen is your present position. It points in the direction you're traveling. The default setting is off, but you can display a solid line extending from the plane's tail to mark your plot trail, or path you've taken. (Remember, a flashing question mark on your plane symbol or flashing text displays means AirMap has not yet calculated a position.) The map zoom range is the distance across the screen. This number shows in the lower left corner of the screen. In the first example below left, the range is 4,000 nautical miles from the left edge of the map to the right edge of the map. In the right image, the range is 30 nm.
Far left, Map Page opening screen, Full Map display option. Center, zoomed to 100 nautical miles and right, zoomed to 30 nautical miles. (Note that the four data boxes or text boxes appearing in the bottom of these images are on by default. They can be individually turned off or you can customize the display to show a different type of information in each box.)
The Zoom In and Zoom Out keys zoom the map to enlarge or reduce its coverage area and the amount of mapping detail shown. There are 40 available map zoom ranges, from 0.02 nautical miles to 4,000 nautical miles. AirMap's high resolution screen makes it possible to display aeronautical chart features that look like the "real thing." If you're familiar with sectional charts, you will instantly recognize items such as obstacles, VORs, special airspaces, paved and unpaved airports and more. As you zoom in closer, you'll see Class B airports appear at a fairly wide zoom. Zoom in closer and Class C and D airports appear, as well as restricted airspaces. At closer zooms still you can even see Class C airspace borders around airports. If you're using only the factory-loaded background map, the maximum zoom range for showing additional land map detail is 6 nautical miles. You can continue to zoom in closer, but the map will simply be enlarged without revealing more map content (except for a few major city streets.) Load your own high-detail custom map made with MapCreate, and you can zoom in to 0.02 nautical miles with massive amounts of accurate map detail.

We've done everything we could with AirMap to make it a powerful navigation tool, but also to keep it simple to use. Sometimes describing all of the options AirMap contains can make it sound hard to use, but it's really not! The following page contains a 12-step quick reference for the most basic aviation GPS operations. If for some reason you don't want to carry the manual with you as you practice with the AirMap, you might consider photocopying this quick reference page and tucking it into your pocket or flight bag.
Start outdoors, with a clear view of open sky. Imagine you're flying to a nearby airport to practice landings. (If you're practicing on foot or by car, substitute a restaurant for an airport. Pick one a few blocks away. While learning, navigation in too small an area constantly triggers alarms. 1. Insert the MMC and batteries. Mount AirMap on the yoke. Connect to electric power and the active antenna. (See install details on page 11.) 2. Turn on the AirMap: press and release PWR key. Press EXIT to clear each of the warning and copyright message screens. 3. Opening screen displays map of North America at the 3,000 nautical mile zoom range. Rotate through three main Page screens by pressing PAGES key, then or key. Switch pages to display Satellite Status Page, then press EXIT to clear the Pages Menu. 4. Wait while unit locates satellites and calculates current position. Process is visible on Satellite Page. This takes an average of 1 minute or less with sky unobstructed by terrain or structures. When the unit acquires position, a tone sounds and a position acquired message appears. 5.

Runway guidance selection message.
Runway extensions are meant to serve as visual references to help you orient the plane as you approach an airport for a landing. The extension appears as a fan-shape, with its tip pointing directly to the touchdown zone or threshold of the runway you're approaching. This allows you to navigate toward the wider end of the fan, so once you turn down the extension you can easily judge how far you've got to touch-down. To turn off an airport extension, press MENU| to CLEAR RUNWAY EXT|ENT|EXIT. Runway Approach Guidance feature The AirMap also uses the Runway Extension command to extend a localizer-type display to the landing runway; we call it the Runway Approach Guidance feature. After selecting a runway extension (see instructions at the bottom of the previous page) the unit will ask "Do you 51
want to setup Runway Guidance?" (See the previous image.) If you want the AirMap to navigate a localizer-type approach, select YES and press ENT. (Select NO if you want to continue your own navigation with a regular runway extension.) When you select Runway Guidance, the unit will display a localizertype fan and create a route automatically for guidance down the runway's extended centerline. Once selected, however, you are no longer navigating your earlier route, because the AirMap assumes you are on radar vectors or your own vectors to intercept final. The HSI and all other CDI displays will now be set to the inbound runway course and will give guidance to left or right of centerline via the CDI display. However, the hollow (white) bearing arrow will continue to point to the runway touchdown zone (TDZ). The automatic route will be created and set to track inbound on the extended runway's centerline from any distance from the airport. If you desire, you can navigate to the notch of the fan for an approximate five mile final approach. Just press (FIND), select CURRENT ROUTE and select the LOC waypoint in the route. If you plan a short approach and want to bypass the use of runway centerline guidance, and navigate directly to the runway threshold, you (FIND), select CURRENT ROUTE and select the TDZ waypoint can press in the route. When the Runway Approach Guidance feature is working, after passing the TDZ the route sequences to the runway center, and then the airport center. After landing and turning the AirMap off, this temporary route is automatically deleted.
For an even more complete runway guidance display, turn on the "Markers" (outer marker) subcategory in the Aviation category. See the Map Categories Drawn topic for more information. Services The Services screen shows you all of the published services available at the selected airport. You can press or to scroll through the listed items, in case the list runs past the bottom of the screen.

Trails

A trail, or plot trail, is a string of position points plotted by AirMap as you travel. It's a travel history, a record of the path you have taken. Trails are useful for repeating a journey along the same track. They are particularly handy when you are trying to retrace your trip and go back the way you came. AirMap lets you save up to 100 trails in its memory. Since you can copy these trails to MMCs in the form of GPS Data Files (*.usr format), the only true limit on the number of trails you can record is the number of MMCs you can carry in your pockets. (For various trail options, see the Trail Options entry in Sec. 5.) Create and Save a Trail AirMap is set at the factory to automatically create and record a trail while the unit is turned on. It will continue recording the trail until the length reaches the maximum trail point setting (default is 2,000, but the unit can record a single trail up to 9,999 points long). When the point limit is reached, AirMap begins recording the trail over itself. 76
To preserve a trail from point A to point B, you must "turn off" the trail by making it inactive before heading to point C or even back to point A. When a trail is set inactive, AirMap automatically creates and begins recording a new trail. Delete a Trail To erase or delete a trail: Press MENU|MENU| to MY TRAILS|ENT| to trail name|ENT| to DELETE TRAIL|ENT| to YES|ENT. Edit a Trail Name To edit a trail name: press MENU|MENU| to MY TRAILS|ENT| to trail name|ENT|ENT. Press or to change the first character, then press to the next character and repeat until the name is correct. Press EXIT|EXIT|EXIT|EXIT to return to the previous page display.
Transferring GPS Data Files Between AirMap and a Computer
To copy GPS Data Files from AirMap's memory to an MMC, see the entry in this section on Save GPS Data Files to an MMC. To copy GPS Data Files from an MMC into AirMap's memory, see the entry in this section on Load GPS Data Files From an MMC. To copy GPS Data Files from an MMC to your computer, see the instruction manual that came with your MapCreate 6 mapping software or your MMC card reader.
Transferring and Loading Custom Maps From Computer to AirMap
Custom maps work only from the MMC card or SD card. When a card containing a Custom Map File is loaded into the unit, AirMap automatically loads the map into memory when the unit is turned on. Instructions for copying Custom Map Files to an MMC are contained in the instruction manual for your MMC card reader and MapCreate 6 software. For instructions on inserting an MMC into AirMap, see Sec. 2, Installation/Accessories.

Utilities

Utilities are useful tools for traveling or for outdoor activities. NOTE: AirMap also includes a set of Aviation-only utilities. These are discussed in Sec. 3, Aviation Utilities. 77

Waypoints

A waypoint is simply an electronic "address," based on the latitude and longitude of a position on the earth. A waypoint represents a location, spot, or destination that can be stored in memory, then be recalled and used later on for navigation purposes. Simply think of it as an electronic address. You can create a waypoint at the cursor position on the map, or at your current position while you are navigating. Create a Waypoint These techniques use the Quick Save method, the fastest and easiest way to create a waypoint.

Create Waypoint on Map

1. Use the arrow keys to move the cursor to the place where you want to make a waypoint. 2. Press ENT|ENT. The waypoint is saved and automatically given a name with a sequential number, such as "waypoint 001." The waypoint symbol and number appear on the map.
Create Waypoint at Current Position While you are traveling, press ENT|ENT. The waypoint is saved and
automatically given a name with a sequential number, such as "waypoint 002." The waypoint symbol and number appear on the map. 78
Create a Man Overboard Waypoint This unit has a man overboard feature that shows navigation data to the location where the feature was activated. To activate it, press the ZOUT and ZIN keys at the same time. Your position at the time these keys are pressed is used as the man overboard position. The unit automatically begins navigating to the MOB waypoint. For further details, see the subject Navigating Back to a Man Overboard Waypoint earlier in this section.
Create a Waypoint by Average Position
This feature sets a waypoint at the current position after taking several position readings and averaging them. This boosts waypoint position accuracy by helping to eliminate errors caused by atmospheric conditions and other factors. 1. Press ENT| to AVERAGE POSITION|ENT|(cursor jumps to highlight CREATE)|ENT. 2. Wait while the unit takes points to average for the position. (The greater the number of points, the greater the accuracy.) When the desired number of points accumulates, press ENT to create and save the waypoint. 3. The Edit Waypoint menu appears. You can simply save the waypoint by pressing EXIT|EXIT or you can edit the waypoint.

Section 5: System & GPS Setup Options

Alarms

This unit has several GPS alarms. You can set an arrival alarm to flash a warning message and sound a tone when you cross a preset distance from a waypoint. For example, if you have the arrival alarm set to 0.1 mile, then the alarm will flash a message when you come within 0.1 mile of the recalled waypoint. The off course alarm warns you when your track drifts too far to the right or left of the course line to the waypoint. For example, if the alarm is set to 0.1 mile, then the alarm flashes a message if you drift 0.1 of a mile or more to the right or left of the line to the waypoint. The anchor alarm is triggered when you drift outside of a preset radius. Again, using the 0.1 mile as an example, if you're anchored and your boat moves more than 0.1 of a mile, the alarm will flash a message and sound a tone. You can use the Alarm Menu to adjust distance settings or to turn alarms off or on. NOTE: The AirMap also includes several Aviation Alarms, which are only available when the unit is in Air Mode. For detailed descriptions of the Aviation Alarms, see the following entry.
Alarms command, left; Alarm menu, right.
To change alarm settings: 1. Press MENU|MENU| to ALARMS|ENT. 81
2. Scroll or to select the desired category, then press ENT to turn the alarm on or off. 3. To change the alarm range, press to DISTANCE|ENT. Press or to change the first character, then press to the next character and repeat until the distance is correct. Then press ENT. 4. To return to the last page displayed, press EXIT|EXIT. IMPORTANT ALARM NOTES: Anchor Alarm The anchor alarm may be triggered even when you're sitting still. This typically happens when using small (less than 0.05 mile) anchor alarm ranges. Arrival Alarm - If you set the arrival alarm's distance to a small number and you run a route (see the Navigate Routes segment), this unit may not show navigation data to the next waypoint, once you arrive at the first one, since you may not be able to come close enough to the first waypoint to trip the arrival alarm.

At left, Setup Loran TD option on the Coordinate System Menu. At right, Configure Loran TD menu.
Map Fix Map Fix is used with charts or maps. This system asks for a reference position in latitude/longitude, which you take from a marked location on the map. It then shows the present position as distance on the map from that reference point. For example, if it shows a distance of UP 4.00" and LEFT 0.50", you then measure up four inches and to the left a half-inch from the reference point on the map to find your location. To configure a map fix: To use this format, you need to follow these steps in order. First, take your map of the area and determine a reference latitude/longitude. (Note: in order for this system to work, the latitude/longitude lines must be parallel with the edge of the map. USGS maps are parallel, others may not be. Also, this works better with smaller scale maps.) The reference position can be anywhere on the map, but the closer it is to your location, the smaller the numbers will be that you'll have to deal with. Once you've decided on a reference position, you can save it as a waypoint. See the waypoint section for information on saving a waypoint. Save the reference position as a waypoint. Exit from the waypoint screens. Now press MENU|MENU| to GPS SETUP|ENT| to COORDINATE SYSTEM|ENT| to SETUP MAP FIX|ENT. The following left screen appears, and MAP SCALE is highlighted. Press ENT and enter the map's scale. This is generally at the bottom of the paper map. It's shown as a ratio, for example 1:24000. Press EXIT and the unit returns to the Configure Map Fix screen. 87
Configure a map fix so AirMap can find your position on a printed chart, sectional or topographical map.
Press to SELECT ORIGIN|ENT|ENT (MY WAYPOINTS) if you saved the reference point as a waypoint. Select the waypoint that you saved the reference point under and press ENT. The unit displays a waypoint information screen with the command SET AS ORIGIN selected; press ENT and the unit returns to the Configure Map Fix menu. Finally, press EXIT to erase this menu. Now press to COORDINATE SYSTEM|ENT, select MAP FIX from the list and press ENT. All position information now shows as a distance from the reference point you chose.

To set Lat/Lon Grid: Press MENU| to MAP DATA|ENT. Press to LAT/LON GRID LINES. With the option highlighted, press ENT to check it (turn on) and uncheck it (turn off).

With the option highlighted, press ENT to check it (turn on) and uncheck it (turn off). After the option is set, press EXIT to return to the page display.

Map Datum Selection

Maps and charts are based on a survey of the area that's covered by the map or chart. These surveys are called "Datums." Maps that are created using different datums will show the same latitude/longitude in slightly different locations. All datums are named. The GPS system is based on the WGS-84 datum, which covers the entire world. Other datums may also cover the entire world, or just a small portion of it. By default, your position shows using the WGS-84 datum. However, it can show your position using one of 191 different datums. To change the datum: 1. Press MENU|MENU| to GPS SETUP|ENT| to DATUM SELECTION|ENT. 2. Scroll or to select the desired datum, then press ENT. 3. To return to the last page displayed, press EXIT|EXIT.

By default, many receivers show 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 traveling 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, AirMap defaults to a track-up 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. Another option is course-up mode, which keeps the map at the same orientation as the initial bearing to the waypoint. When either the track-up or course-up mode is on, an "N" shows on the map screen to help you see which direction is north.

Navionics Charts

Your unit can display Navionics electronic charts on MMCs. Both the GOLD and CLASSIC format charts are accepted. They work just like a MapCreate custom map on an MMC. WARNING: You should never format the MMC containing your Navionics chart. Formatting the MMC will permanently erase the chart from the card. To display a Navionics chart: 1. Install the Navionics MMC in the memory card compartment and turn on the unit. (For full card install instructions, see Sec. 2.) 2. From the Map Page, press MENU| to MAP DATA|ENT| to NAVIONICS MAP CHOICE|ENT. Use or to select the Map Name, then press ENT|EXIT|EXIT.
