NAVIGATION MODE (GPS)
NOTE: The navigation receiver must have an active GPS course for the flight
director to enter Navigation Mode.
NOTE: When intercepting a flight plan leg, the flight director gives com-
mands to capture the active leg at approximately a 45° angle to the track
between the waypoints defining the active leg. The flight director does not
give commands fly to the starting waypoint of the active leg.
Pressing the NAV Key selects Navigation Mode. Navigation Mode acquires and
tracks the navigation source. The flight director follows GPS roll steering commands
when GPS is the navigation source. Navigation Mode can also be used to fly non-
precision GPS approaches where vertical guidance is not required.
If the Course Deviation Indicator (CDI) shows greater than one dot when the NAV
Key is pressed, the selected mode is armed. If the CDI is less than one dot, Navigation
Mode is automatically captured when the NAV Key is pressed. The armed annunciation
appears in white to the left of the active roll mode.
If Navigation Mode is active and either of the following occur, the AFCS
reverts to Roll Hold Mode (wings rolled level):
• Active navigation source manually switched
• Active flight plan is deleted
• GPS reception is lost
