Garmin Pilot 3 Manual

							The GPS III PilotÕs Main Menu provides access to the waypoint, route, track log,
trip planning and setup features of the receiver. The Main Menu can be accessed at any
time using the MENU key.
To display the Main Menu, press the MENU key twice.
The 7 menu options are divided into categories by function: waypoints/routes/
track log, trip computer, vertical navigation/E6B and system setups.
To select an option from the Main Menu, highlight the desired item and
press ENTER.
The following menu options are available:
WaypointsÑ allows you to review database information and create/edit/delete
user waypoints. See pages 48-52 and pages 55-59.
RoutesÑ allows you to create, edit, activate or delete routes. See pages 66-70.
Track LogÑ lets you specify whether or not to record a track log (an electronic 
Ôbreadcrumb trailÕ recording of your path) and defines how it is recorded. This
submenu page also provides an indicator of the percentage of track memory used
and options to clear the track memory or start a TracBack route. See pages 64-65
for TracBack information.
Press MENU twice to display
the Main Menu.
Select the desired menu option
by highlighting it with the
rocker keypad and pressing
ENTER.

							Track Log Settings
Record Modelets you select one of three track recording options:
ÔOff Õ Ð No track log will be recorded.
NOTE: Selecting ÔOff Õ will prevent you from using the TracBack feature.
ÔFillÕ Ð A track log will be recorded until the track memory is full.
ÔWrapÕ (default) Ð A track log will be continuously recorded by wrapping through
available memory and replacing the oldest track data with new data.
Intervaldefines the frequency with which the track plot is recorded. Three interval
settings are available:
ÔTimeÕ Ð Records track log based on a user-defined time interval.
ÔResolutionÕ (default) Ð Records track log based upon a user-defined variance from
your course over ground. The resolution option is recommended for the most
efficient use of memory and TracBack performance. The distance value (entered in
the ÔInterval ValueÕ field) is the maximum left/right deviation allowed from the last
defined ground track before recording a new point.
ÔDistanceÕ Ð Records track log based on a user-defined distance between points.
Interval Valuedefines the distance or time interval used to record the track log.
Clear Logallows you to clear the track log data currently stored in memory.
To delete the track log data, highlight ÔDelete TrackÕ and press ENTER.
TracBackconverts the track log data in memory into an inverted route and begins
navigation along the route. See pages 64-65.
ÔFillÕ will record track log data
until memory is full, then pro-
vide a ÔTrack Memory FullÕ
message.
To utilize the TracBack fea-
ture, you should clear the
track log before leaving the
departure airport.

Vertical NavÑ allows you to define a vertical navigation profile used to descend
(or climb) to a target altitude at a specified location. See pages 43-45.
E6BÑ provides calculation features for density altitude, true airspeed and winds
aloft. The winds aloft function will calculate wind direction, speed and the head/tail
wind component.

1. Select the ÔDensity AltitudeÕ file tab using the rocker keypad.
2. Highlight the ÔIndicated AltitudeÕ field and press ENTER. Enter the altitude from your
altimeter and press ENTER. 
3. Highlight the ÔCalibrated AirspeedÕ field and press ENTER. Enter the airspeed from
your airspeed indicator and press ENTER.
4. Highlight the ÔPressureÕ field and press ENTER. Enter the current altimeter setting
(barometric pressure) and press ENTER.
ÔTrip ComputerÕ provides
readouts for the trip odometer,
trip timer, average speed and
maximum speed. Options are
provided to reset these figures.
Density altitude and true air-
speed may be calculated by
entering values for indicated
altitude, calibrated airspeed,
barometric pressure and total
air temperature.

2. Highlight the ÔHeadingÕ field and press ENTER. Enter the current aircraft heading and
press ENTER. 
3. Highlight the ÔTrue AirspeedÕ field and press ENTER. Enter the current true airspeed 
and press ENTER. (If the true airspeed was previously determined on the ÔDensity
AltitudeÕ page, the calculated figure will automatically appear here as the default.)
4. The ÔHead (Tail) WindÕ, ÔWind FromÕ and ÔWind SpeedÕ figures will appear at the bottom
of the page.
SetupÑ provides a group of pages to perform various system setup functions,
including selection of position format, units of measure, setting various alarms, con-
figuring the display and backlighting. Each available page is denoted by a Ôfile tabÕ
which identifies the function of that page. 
To select a Setup option, highlight the file tab for the desired function.
The information is automatically displayed when the file tab is highlighted.
The ÔWindsÕ option allows you
to calculate the current head-
wind or tailwind component.
The ÔSetupÕ option uses file
tabs for quick selection/review
of unit settings.

							Units Settings
Distance & Speedlets you select the desired units of measure for distance and speed
readouts in ÔNauticalÕ, ÔStatuteÕ or ÔMetricÕ terms.
Headinglets you select the reference used in calculating heading information. You can
select from ÔAuto Mag VarÕ, ÔTrueÕ, ÔGridÕ and ÔUser Mag VarÕ. ÔAuto Mag VarÕ provides
magnetic north heading references which are automatically determined from your current
position. ÔTrueÕ provides headings based upon a true north reference. ÔGridÕ provides
headings based on a grid north reference (and is used in conjunction with the grid posi-
tion formats described on page 84). ÔUser Mag VarÕ allows you to specify the magnetic
variation at your current position and provides magnetic north heading references based
upon the variation you enter.
Altitudelets you select altitude readouts in ÔFeetÕ or ÔMetersÕ.
Vertical Speedlets you select a vertical speed in ÔFeet/MinuteÕ or ÔMeters/MinuteÕ.
Pressurelets you select altimeter settings (barometric pressure) in ÔInchesÕ or ÔMillibarsÕ.
Temperaturelets you select temperature readouts in degrees ÔFahrenheitÕ or ÔCelsiusÕ.
To select a units setting:
1. Highlight the desired field and press ENTER to display the available options.
2. Select the desired option and press ENTER.
3. If ÔUser Mag VarÕ is selected in the ÔHeadingÕ field, highlight the heading reference field (immed-
iately to the right) and press ENTER. Enter the magnetic variation at your current position using 
the rocker keypad and press ENTER.
WARNING: If ÔUser Mag VarÕ is selected, you must periodically update the magnetic varia-
tion as your position changes. Using this setting, the GPS III Pilot will not automatically cal-
culate and update the magnetic variation at your present position. Failure to update this set-
ting may result in substantial differences between the information displayed on your GPS III
Pilot and external references, such as a magnetic compass.
Select nautical, statute or
metric units of measure from
the ÔUnitsÕ settings.
The ÔUser MagÕ option allows
you to define the magnetic
variation for your area. ÔAuto
Mag VarÕ is the preferred set-
ting in most cases.

Local Time Zoneis used to define the current local time. UTC date and time are calcu-
lated directly from the satellitesÕ signals and cannot be edited. If you prefer to use local
time, you may designate an offset, either ÔBehind UTCÕ or ÔAhead of UTCÕ. The offset is
the difference, in hours and minutes, between local time and UTC time.
To enter the local time zone:
1. Highlight the ÔLocal Time ZoneÕ field and press ENTER.
2. Select the desired offset amount (in hours and minutes) using the rocker keypad and press ENTER.

provided by the satellites received.
Datedisplays the current date based on the settings made above and information 
provided by the satellites received.
Enter an offset amount to
adjust the time display to
your local area. In the United
States, all offset amounts will
be ÔBehind UTCÕ.
If youÕre unsure of the exact
offset select a ÔLocalÕ time for-
mat, then enter offset values
until you arrive at the correct
local time.
