2.8.7.9 Waypoint Annunciation
P5-66 Waypoint Annunciate
The Waypoint annunciator functions as follows:
•
When the aircraft is within 10 to 20 seconds of reaching a turning point for a course change, the
waypoint annunciator flashes.
•
When the aircraft is in a turn, the waypoint annunciator illuminates continuously and remains
illuminated until the turn is completed.
•
When the turn is complete and deviation information is being provided relative to the next leg, the
waypoint annunciator will extinguish.
If an external annunciator is used for waypoint annunciation, it is recommended that the waypoint
annunciator be labeled “WPT” in white text.
2.8.7.10 Terminal Mode Annunciation
P5-67 Terminal Mode Annc
The Terminal Mode Annc output is grounded when navigating within 30 nmi of the departure or arrival
airport, or on a SID or STAR.
If an external annunciator is used for terminal mode annunciation, it is recommended that the terminal
mode annunciator be labeled “TERM” in green text.
