DELETING AN APPROACH WAYPOINT
1. Display the appropriate FPL Page.
2. Line Select Key - DEPRESS to position cursor over the
APPROACH waypoint identifier to be deleted.
3. BACK Key - DEPRESS. A DELETE? prompt will appear adja-
cent to the waypoint.
4. ENT Key - DEPRESS.
NOTE: When an APPROACH is modified by adding or deleting way-
points (including waypoints between the “fence” and the Missed
Approach Procedure waypoint), the sequence of waypoints is no
longer identified as an (APPROACH) and the system will not enter
the Approach Mode. An (APPROACH CANCELED) message will
be displayed anytime a waypoint is deleted or added to an
APPROACH procedure on the Active Flight Plan.
NOTE: Anytime a Direct To the MAP is performed and an approach
is either armed or active, an APPROACH CANCELED message will
appear. The approach functions will be disabled and the CDI scaling
will return to the TERMINAL sensitivity of 1NM full scale deflection.
USING A STAR AND AN APPROACH IN THE SAME FLIGHT PLAN
Since both the Arrival (STAR) and Approach procedures allow for
entry of AIRPORT and RUNWAY, the following rules apply.
• Changing the AIRPORT on the ARRIVAL Page, and selecting an
associated STAR, automatically erases the APPROACH procedure.
• Changing the AIRPORT on the APPROACH Page, and selecting an
associated Approach, automatically erases the STAR procedure.
• Changing the RUNWAY on the ARRIVAL Page, and selecting it,
automatically erases the APPROACH procedure.
• Changing the RUNWAY on the APPROACH Page, and selecting it,
has no effect on the STAR procedure unless the STAR is runway
dependent.
If the STAR is runway dependent, the message “SEL RWY FROM
STAR PG” (Select RUNWAY from STAR Page) appears on the
APPROACH Page. The pilot must return to the ARRIVAL Page to
change the RUNWAY for the STAR, before changing the RUNWAY
on the APPROACH Page.
