Press and hold this key to mark present position as a waypoint. (QUIT) Returns the display to a previous page or restores a data fields previous value. (IN and OUT) Allows you to zoom in/out through 23 scales on the Map Page. Also adjusts scale on the Highway and HSI pages. (ROCKER KEYPAD) Controls the movement of the cursor, is used to select options and positions, and to enter data. 2 Example of Cursor highlighting the Mode Field
CURSOR A solid black bar which can be moved up, down, left, and right with the keypad to select individual fields on the display (see above). DEFAULT A system-selected format, built into the operating software or the units memory, that will be followed unless the user chooses a different setting. FIELD The location on a page (see above) where a group of characters or option is entered and displayed. HIGHLIGHT The act of using the cursor to select a field for the purpose of entering data. SCROLL The act of moving through characters or options from a selected field. DATA ENTRY Entering data, such as waypoint names, typically begins and ends with the ENTER/ MARK key. Use the rocker keypad to enter the actual data: UP/DOWN to change the highlighted character, RIGHT to move on to the next character.

The Welcome Page is displayed when the GPS III Pilot is first turned on. During this time the receiver is conducting a self-test. 5

Initialization This usually provides a position fix in one minute. Youll know you have a fix when the unit automatically transitions from the Satellite Page to the Map Page (shown bottom left). Your receiver is now ready to use! To turn the unit off:
1. Press and hold the red power key for one second.
To initialize the GPS III Pilot, designate your approximate location directly on the map display. Use the rocker keypad and IN/OUT zoom keys to position the cursor on the map.
Once the GPS III Pilot has a position fix, it will automatically transition from the Satellite Status Page to the Map Page. 6
Troubleshooting If you have trouble initializing or getting a position fix, check the following: Does the receiver have a clear view of the sky? If there are large buildings or mountains, or if there is heavy tree cover, the receiver may not be receiving enough satellite signals to calculate a fix. Also, if youre using the GPS III Pilot inside the cockpit, make sure the unit is placed so that it has the clearest possible view of the sky. Your GPS will only be able to detect satellites that it can see through your vehicles windshield. Depending on the slope of glass or the overall surface area, it may be necessary to remote mount an antenna inside the cockpit or install an outside antenna. (Contact your local GARMIN dealer and inquire about the GA 26 Remote Antenna, part number 010-1005202, or the GA 56 Low Profile Antenna, part number 010-10040-01.) Have you selected the right area when initializing? Check for the correct approximate position on the Map Page (press PAGE until the Map Page appears; see pages 7 and 10), or reselect your approximate location to restart the initialization. Have you moved more than 500 miles from the last calculated position with the receiver off? Reinitialize the receiver by selecting your approximate position on the map, or select AutoLocate from the Satellite Status Page Options (see page 31).

1. Press the IN zoom key to select a smaller scale and display a smaller geographic area. 2. Press the OUT zoom key to select a larger scale and display a larger geographic area.
The map can be oriented with the top of the page always pointing north (North Up), oriented along your desired course (Course Up), or it can automatically rotate to keep your current direction of travel at the top of the screen (Track Up). Lets try panning around on the map display to see how that process works, and then well find a nearby airport, VOR, NDB or intersection and navigate to it. First we will need to select an appropriate map scale to begin our search. Select a five nautical mile scale by pressing zoom IN or OUT repeatedly.
Use the IN/OUT zoom keys to change the map scale. The current scale appears in the lower-left corner of the map display. 19

Viewing Waypoint Info Working from the Map Page is a simple process that centers around the use of the cursor. Controlled by the rocker keypad, the cursor is an important tool allowing you to pan to other areas on the map display, view waypoint information, create waypoints, specify a GOTO target and create routes. To get a feel for using the Map Page and the cursor, try the following exercise:
1. Using the rocker keypad to move the cursor, try following a highway (or other feature) near your position. Simply press and hold one side of the rocker keypad to move more quickly. Notice how a data field appears above the map, showing the bearing and distance from present position to the cursor, along with the latitude/ longitude of the cursor. 2. Using the rocker keypad, continue moving the cursor in any direction until you find an airport or navaid. Once you find one, place the cursor over that waypoint so that its identifier is highlighted. 3. Press ENTER to view the database information for the selected waypoint. If an airport is selected, use the LEFT/RIGHT keys on the rocker keypad to select between Airport, Runway and Comm information pages.
Use the rocker keypad to pan to other areas on the map display. When panning, an on-screen cursor appears for reference.

1. Highlight Set OBS and Hold and press ENTER. An OBS data field will appear on the HSI display. 2. Select the desired OBS course using the LEFT/RIGHT keys on the rocker keypad and press ENTER. The D-bar on the CDI and the desired course pointer will now provide steering guidance to the selected course.

HSI Page Options

The Set OBS and Hold option allows you to specify an inbound heading to a destination waypoint.
To cancel the OBS course and reset a direct course to the waypoint, press GOTO and ENTER (or re-activate the route).
Use the rocker keypad to select the desired OBS heading. Note the heading at bottom center of HSI display (155 in this example). 41

Page 42

HSI Page Options Release Hold cancels the hold feature enabled when the Set OBS and Hold option was selected. This option returns the GPS III Pilot to automatic sequencing of waypoints along the active route. However, if an OBS course has been selected, that course setting will be retained until cancelled (as described on page 41) or until waypoint passage. To release a waypoint hold and return to automatic sequencing of route waypoints, highlight Release Hold and press ENTER. Big Numbers allows you to select a different page layout, with a smaller compass-type display and two user-selectable, large-character data fields. If Big Numbers is selected, HSI will appear as an option instead. To toggle between HSI and Big Numbers page formats, highlight Big Numbers (or HSI) and press ENTER. Change Fields allows you to choose the data displayed on four user-selectable data fields. There are twenty-nine available data types, including Average (AVG) Speed, Bearing, Distance, ETA at Destination (DEST), Speed, Time to Destination (DEST), Track, and a Trip Odometer. See page 98 for descriptions of data terms. To change a data field:
Big Numbers provides a smaller compass-type display, with a pointer indicating the bearing to your destination.
The Change Fields option allows you to select from a list of available data types. Four different items may be displayed on the HSI Pages userselectable data fields.

Page 43

Capture VNAV Profile is used to center/re-center the VNAV indicator (see illustration to the right) on the HSI display. To utilize this feature, a GOTO or route must be in use and a valid vertical navigation profile must be entered on the vertical navigation setup page (see the following page and page 75). Cancel Capture is used to return the VNAV indicator to the settings originally entered on the vertical navigation setup page (see the following page and page 75). Vertical Navigation
When using the vertical navigation features, a VNAV indicator (moving horizontal bar) will guide you as you descend to the target altitude.

1. Press the IN zoom key to decrease the scale and show a smaller view area. 2. Press the OUT zoom key to increase the scale and show a larger view area.
Your course is represented by the highway center line. Keep the center line in the middle of the display to stay on course.
When using a route, the Highway Page will guide you to each waypoint along the route. 46

Page 47

Many features of the GPS III Pilot are menu driven. Each of the main pages has an options menu, allowing you to custom tailor the corresponding page to your preferences and/or select special features which specifically relate to that page. To display the Highway Page Options, press MENU (with the Highway Page displayed). The following options are available: Sign Posts Off removes the waypoint markers from the highway display. If Sign Posts Off is selected, Sign Posts On will appear as an option instead. To remove (or display) waypoint markers on the highway, highlight Sign Posts Off (or Sign Posts On) and press ENTER. Change Fields allows you to choose the data displayed on four user-selectable data fields. There are twenty-seven available data types, including Average (AVG) Speed, Bearing, Distance, ETA at Destination (DEST), Speed, Time to Destination (DEST), Track, a Trip Odometer and a bearing pointer. See page 98 for descriptions of navigation terms. To change a data field:

Page 48

Waypoint Categories Your GPS III Pilot uses a built-in Jeppesen database to provide position and facility information for thousands of airports, VORs, NDBs and intersections. Each facility in the database is stored as a waypoint, with its own latitude/longitude, identifier (up to six letters and/or numbers) and other pertinent information. Waypoint information is available from the Waypoints selection under the Main Menu. Waypoint information is divided into categories (each represented by a file tab), with different types of information available for each. The following table lists the file tabs and information available under each tab: Airport Runway Comm Identifier, city/state, name, position, elevation, fuel Length, width, orientation, surface, lighting, diagram Frequencies for: ATIS, pre-taxi, clearance, ground, tower, unicom, multicom, approach, departure, arrival, class B, class C, TMA, CTA, TRSA VOR Identifier, city/state, facility name, position, freq., indication of co-located DME or TACAN NDB Identifier, city/state, facility name, position, freq. Int Intersection name, region/country, nearest VOR User Wpt Name, position, user comments, reference waypoint User List Name, symbol, total number of user waypts created To view waypoint information:

1. Press MENU twice to display the main menu. 2. Highlight Waypoints using the rocker keypad and press ENTER. One of the waypoint information pages listed above will be displayed. 3. A series of tabs across the top of the page will indicate the other available pages. Select the desired page using the rocker keypad.
The Main Menus Waypoints option allows you to view database information for airports, runways, comm frequencies, VORs, NDBs, etc.
Select the desired waypoint category by selecting the corresponding file tab at the top of the page. 48

Waypoint Category File Tabs Waypoint Identifier Field Waypoint Symbol Field
Waypoint Information Pages
To select the desired waypoint, by identifier:
1. Highlight the waypoint identifier field using the rocker keypad and press ENTER. 2. Use the rocker keypad to enter the desired identifierUP/DOWN to change each character and RIGHT to move to the next character. 3. As the identifier is entered, the GPS III Pilot will scroll through the database, displaying any waypoints with the same identifier letters you have entered to that point. When the desired waypoint is displayed, press ENTER.
Waypoints are selected by identifier (or name). Enter the desired identifier in the waypoint identifier field, using the rocker keypad.
? NOTE: The GPS III Pilot uses International Civil Aviation Organization (ICAO) identifiers to designate airports. In the United States, the prefix letter for airports is K. This applies to airport identifiers that are letters only. For example, LAX becomes KLAX and JFK becomes KJFK. Airport identifiers that use numbers, such as H34 or 7M5, do not use the K prefix. Some waypoints in the database may have the same identifier. When you have entered a waypoint name that is not unique, a Duplicate Waypoint Page appears, prompting you to select the desired waypoint. A list showing each duplicate by waypoint category and region/country makes it easy to identify the correct one. To select the desired waypoint from a list of duplicates, highlight the desired waypoint and press ENTER.
If more than one waypoint uses the same identifier, the Duplicate Waypoint Page allows you to choose the correct one. 49

Page 50

Waypoint Information Pages The Airport, VOR and NDB information pages also allow you to retrieve the desired waypoint by entering the facility name or the city name. To select the desired waypoint, by facility or city name:

1. Use the rocker keypad to highlight the facility name or city name field. Press ENTER. 2. Use the rocker keypad to enter the desired nameUP/DOWN to change each character and RIGHT to move to the next character. 3. As the name is entered, the GPS III Pilot will scroll through the database, displaying any waypoints with the same letters you have entered to that point. In some instances there may be more than one waypoint with the desired name. (This often occurs when searching by city name.) To view all waypoints with the desired name, continue spelling the name with the rocker keypad. Once the name appears on-screen, continue to press UP/DOWN on the rocker keypad to view all entries for that name. 4. When the desired waypoint is displayed, press ENTER.
