GPS Receiver User Manual

The heading up mode orients the map with the aircraft’s heading as up.
The heading up orientation is not presented as a choice if heading is not
provided to the KLN 94.
If a heading input is available to the KLN 94 then heading up is usually the
best map orientation to select. Otherwise, actual track up display is usual-
ly preferred for use in flight. However, since the track up display is only
usable when the aircraft is moving two knots or more the North up display
may be a good choice if you are stationary.
CAUTION: When using the actual track up format it is typical for
there to be a slight delay from the time a heading change is made
until the correct map orientation is displayed. Be careful when using
either the desired track up display or the actual track up display to
not think that a heading up display is being used.
To change the map orientation:
1. Select the NAV 4 (map) page if
not already displayed. The easi-
est way to do this is to press
either the map range (R) button
or the map menu (M) button.
2. Press the M button to display
the Map Menu page (figure 3-
132).
3. Rotate the right outer knob
clockwise to position the cursor
over the map orientation (figure
3-133).
4. Select the desired map orienta-
tion by turning the right inner
knob (figure 3-134).
5. Press the R button or M but-
ton to return to the map using the selected orientation.
3.11.4.9. Changing the Map Range Scale
The map range scale is displayed in the bottom left corner of the map.
The number displayed is the distance in nautical miles from the aircraft’s
present position symbol to the top of
the screen. The 10 NM scale is
selected in figure 3-135. Press the
upper portion of theRbutton to
increase the range scale and the
bottom portion to decrease the range
