this is the NAV 4 page anyway, because of its unique graphics.
The left side of the screen displays the distance to go, active way-
point identifier, and mode annunciation (either Leg, or the OBS
selected course), just like it usually would, but the fourth line is a
cyclic field for which you may select:
Magnetic Desired Track (degrees)
DTK123
Groundspeed (knots)
123kt
Estimated Time Enroute (hours:minutes)
1:23
Crosstrack Correction (nautical miles)
1.23
→
NOTE: Magnetic desired track may only be selected when KLN 35A
is in the Leg navigation mode. When the KLN 35A is in the OBS
mode, the “desired track” is the same as the OBS selected course
displayed on line 3.
To change the data displayed in this
cyclic field, simply turn on the cursor
(
B
), rotate the right outer knob
counterclockwise to position the cur-
sor over this field (figure 3-121), and
press the
E
button to choose the desired information.
Now we move on to the map display area on the right side of the
screen. In all KLN 35A installations there are three common map ori-
entation formats that may be selected on the NAV 4 page: a True
North up display, a desired track up display, or an actual track up dis-
play. When the North up display is selected, viewing the NAV 4 page
is like looking at a navigation chart with North at the top. When the
desired track up display is selected the NAV 4 page is like looking at
a chart that is turned so that your course line is always pointing up.
When the actual track up display is selected, viewing the NAV 4 page
is like looking at a chart that is turned so that the direction the aircraft
is tracking over the ground is pointing up. In a no-wind condition,
actual track is identical to the aircraft’s heading.
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.
