Garmin Pilot 3 Manual

							Capture VNAV ProfileÑ is used to center/re-center the VNAV indicator (see illus-
tration 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 navi-
gation setup page (see the following page and page 75).
Cancel CaptureÑ 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
The GPS III PilotÕs vertical navigation feature allows you to create a three-
dimensional profile which guides you from your present position and altitude to a 
final (target) altitude at a specified location. Once the profile is defined, message alerts
and additional data on the HSI Page will keep you informed of your progress.
NOTE: To use the vertical navigation feature, your speed must be greater than 35
knots and you must be navigating to a GOTO destination or using a route.
When using the vertical 
navigation features, a VNAV
indicator (moving horizontal
bar) will guide you as you
descend to the target altitude.
The Main MenuÕs ÔVertical NavÕ
option allows you to define the
target altitude and where it
should occur. The default set-
tings are intended to guide you
to pattern altitudes.

							To create a vertical navigation profile:
1. Select the Main Menu by pressing MENU twice.
2. Select ÔVertical NavÕ using the rocker keypad and press ENTER.
3. With the ÔTarget AltitudeÕ field highlighted, press ENTER. Enter the desired target alti-
tude and press ENTER.
4. With the altitude reference field (immediately to the right of ÔTarget AltitudeÕ) high-
lighted, press ENTER. Select ÔAbove WptÕ or ÔMSLÕ (as desired) and press ENTER.
ÔAbove WptÕ  will use the altitude of a destination airport as stored in the internal
Jeppesen database. ÔMSLÕ lets you set a specific target altitude for any waypoint 
category: airport, VOR, NDB, intersection or user waypoint.
5. With the waypoint distance ÔByÕ field highlighted, press ENTER. Enter an offset dist-
ance from the destination waypoint where the target altitude should be reached. If
the target altitude occurs at the destination waypoint, enter a distance of zero. Press
ENTER when finished.
6. With the offset direction field (immediately to the right of ÔByÕ) highlighted, press
ENTER. Select ÔBeforeÕ or ÔAfterÕ and press ENTER. This setting designates whether
the offset distance defines a point before you reach the destination waypoint or after
you reach the destination waypoint.
7. When using a route, the ÔVNav WaypointÕ field allows you to specify which route
waypoint will be used for the vertical navigation profile. By default, the GPS III Pilot
will select the last waypoint in the route. To select a different waypoint, highlight the
ÔVNAV WaypointÕ field, press ENTER, select the desired waypoint and press ENTER.
8. The default profile utilizes a 400 foot-per-minute descent rate. To change the rate,
highlight the ÔProfileÕ field, press ENTER, enter a new rate and press ENTER again.
9. To enable/disable all vertical navigation messages, highlight the ÔMessageÕ field and
press ENTER. Select ÔOnÕ or ÔOffÕ (as desired) and press ENTER.
Your target altitude can be
defined as height ÔAbove WptÕ
or ÔMSLÕ. ÔAbove WptÕ only
applies to airports. Use ÔMSLÕ
for all other waypoint types.
When using a route, vertical
navigation can apply to any
waypoint along the route by
selecting it as the ÔVNAV
WaypointÕ.

							With the profile set, the HSI Page will guide you through the maneuver. Data fields
on the HSI Page can be configured to indicate the time to beginning of maneuver, glide
ratio and vertical speed to target. A VNAV indicator on the HSI display will guide you
along the proper descent angle. Expect the following to occur when using the vertical
navigation feature:
¥ As you approach the initial descent point, the time to vertical navigation
(ÔTime to VNVÕ) field indicates the time to reach the initial descent point.
¥ At one minute prior to the initial descent point, a message ÔApproaching
VNAV ProfileÕ occurs. The time to vertical navigation (ÔTime to VNVÕ) will
sequence from indicating time to initial descent point to indicating time to
reach target altitude. Finally, the descent angle will lock to prevent changes
in speed from altering the profile.
¥ At 500 feet above the target altitude, an ÔApproaching Target AltitudeÕ mes-
sage is provided. The time to vertical navigation (ÔTime to VNVÕ) figure will
go blank and the VNAV indicator will disappear from the HSI Page.
WARNING: GPS accuracy may be degraded by the U.S. Department of Defense-
imposed Selective Availability (SA) program. With ÔSAÕ on, GPS altitude may be in error
by several hundred feet. Errors of this magnitude may result in fluctuations in the
VNAV indicator on the HSI Page. The GPS III Pilot is a VFR navigation tool and should
not be used to perform instrument approaches.
Within one minute of the 
initial descent point, an
ÔApproaching VNAV ProfileÕ
message will appear.
Once you are within 500 feet
of the target altitude, the
ÔApproaching Target AltitudeÕ
message will appear and the
VNAV indicator will be
removed from the HSI 
display.

							Whenever a destination waypoint(s) has been selected, the GPS III PilotÕs
Highway Page will guide you to your destination with digital readouts and a high-
way display. Along the right side of the page (top, when display is vertical) are four
user-selectable data fields that display current speed, distance and time to next way-
point, and a bearing pointer (defaults). The bearing pointer always points to the des-
tination waypoint (or the next waypoint when using a route) relative to the direction
you are moving (track). If the bearing pointer points straight ahead, you are heading
directly to your destination. If the bearing pointer points any direction other than
up, turn toward the arrow until it points upÑthen continue in that direction.
The graphic heading compass at the top of the page indicates the direction you are
moving (track). Directly below the heading compass, the highway display provides
visual guidance to the destination waypoint and keeps you on your intended course
line. Your course is represented by the center line down the middle of the graphic
highway. As you head toward your destination, the highway perspective will move to
indicate your progress to the waypoint and which direction you should steer to stay on
course. If you are navigating a route, the highway display will show each route way-
point in sequence, with the route course indicated by a black highway. Nearby airports
not in the route will also be displayed. Five available scale settings allow you to zoom
in or out on the highway display for a smaller or larger view. The current scale setting,
ranging from 1X to 16X, appears on the lower right corner of the highway display.
To zoom in or out on the highway display:
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.

							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, iden-
tifier (up to six letters and/or numbers) and other pertinent information. Waypoint
information is available from the ÔWaypointsÕ selection under the Main Menu.
Waypoint information is divided into categories (each represented by a Ôfile tabÕ),
with different types of information available for each. The following table lists the file
tabs and information available under each tab:
Airport Identifier, city/state, name, position, elevation, fuel 
Runway Length, width, orientation, surface, lighting, diagram
Comm 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 ÔWaypointsÕ 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.

							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 identifierÑUP/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.
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 ÔKÕ.
This applies to airport identifiers that are letters only. For example, ÔLAXÕ becomes
ÔKLAXÕ and ÔJFKÕ becomes ÔKJFKÕ. Airport identifiers that use numbers, such as ÔH34Õ
or Ô7M5Õ, do not use the ÔKÕ 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 way-
point 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.
Waypoints are selected by
identifier (or name). Enter the
desired identifier in the way-
point identifier field, using the
rocker keypad.
If more than one waypoint
uses the same identifier, the
Duplicate Waypoint Page
