When the active waypoint is a VOR, and the AUTO magnetic
variation mode is active (see
netic variation for the VOR is utilized rather than the calculated
magnetic variation, so that the KLN 89(B) indication will be identi-
cal to a NAV receiver indication.
4.7.4. SWITCHING FROM THE LEG MODE TO THE OBS MODE
The following mode transition occurs if the KLN 89(B) is in the Leg
mode and the mode is changed to the OBS mode.:
1.
The waypoint that was active in Leg mode prior to the mode
change remains the active waypoint in OBS mode.
2.
The selected course is defined by two different methods depend-
ing on the installation and the status of the unit.
i. If the KLN 89(B) is the displayed navigation source when the
change is made to OBS mode, then the selected course
becomes whatever was set on the external indicator prior to
changing to the OBS mode. This value should normally be the
desired track to the active waypoint if you had the external indica-
tor set to the correct value prior to switching to the OBS mode.
ii. If the KLN 89(B) is not displayed on the external indicator,
then the selected course is chosen such that the deviation from
the selected course remains the same.
3.
If the OBS value chosen by default from rule 2 above is unac-
ceptable, you can always define the desired course by the
methods described in
4.7.5.
EFFECTS OF SWITCHING FROM OBS MODE TO LEG
MODE
The following mode transition occurs if the KLN 89(B) is in the OBS
mode with a TO indication and the mode is switched to the Leg
mode:
1.
The waypoint that was active while in the OBS mode remains the
active waypoint when the Leg mode is activated. The system
does not attempt to orient itself on a leg of the active flight plan
unless the TO/FROM indicator is indicating FROM. In the FROM
case, the KLN 89(B) will reorient on the active flight plan.
2.
The selected course (Obs) that was active in the OBS mode
prior to switching to Leg mode becomes the desired track (Dtk) in
