PREVENTING AUTOMATIC LEG CHANGES
The Auto Leg change function allows the system to automatically
sequence from waypoint to waypoint on the Active Flight Plan. When
the system is initialized it is in the Automatic Leg Change Mode
unless changed by the pilot. The following procedure inhibits auto-
matic leg changes.
1. NAV Key - DEPRESS to display NAVIGATION Page 1.
2. Line Select Key - DEPRESS to position cursor over -AUTO-.
3. BACK Key - DEPRESS.
Cursor field displays
MAN? to inform the pilot
of the pending change.
(Figure 3-176)
4. ENT Key - DE-PRESS.
The cursor disappears
and -MAN- remains in
the field confirming that
leg changes must be
made manually. NO
AUTO LEG CHG mes-
sage appears on the SYSTEM MESSAGES Page, however the
MSG light does not illuminate.
Returning to Automatic Leg Change Mode
1. NAV Key - DEPRESS to display NAVIGATION Page 1.
2. Line Select Key - DEPRESS to position cursor over -MAN-.
3. BACK Key - DEPRESS. Cursor field displays AUTO? to inform
the pilot of the pending change.
4. ENT Key - DEPRESS. The cursor disappears and -AUTO-
remains in the field confirming return to the Automatic Leg
Change Mode. NO AUTO LEG CHG message on the SYSTEM
MESSAGES Page disappears unless the current TO waypoint is
the last waypoint on the Active Flight Plan.
NOTE: Certain HDG Intercept and Pseudo VORTAC Procedures
automatically put the leg change mode into -MAN-. The pilot must
determine if -MAN- or -AUTO- is appropriate then select the desired
leg change mode.
