Basic GPS Operation
Chapter 3
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 or kilometers/hour) 123kt
Estimated Time Enroute (hours:minutes) 1:23
Crosstrack Correction 1.21 ∆ ∆
NOTE: Magnetic desired track may only be selected when
KLN 89(B) is in the Leg navigation mode. When the KLN 89(B) 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 inner knob
counterclockwise to position the cur-
sor over this field (figure 4-125), 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 89(B) installations there are three common map
orientation 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. In addition, if the KLN 89(B) is interfaced with a source of
heading in a compatible format then a heading up presentation may
also be selected. 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.
