AUTOMATIC FLIGHT CONTROL SYSTEM
7.3 FLIGHT DIRECTOR MODES
Flight director modes are normally selected independently for the pitch and roll axes. Unless otherwise specified,
all mode keys are alternate action (i.e., press on, press off). In the absence of specific mode selection, the flight
director reverts to the default pitch and/or roll modes(s).
Armed modes are annunciated in white and active in green in the AFCS Status Box. Under normal operation,
when the control for the active flight director mode is pressed, the flight director reverts to the default mode(s) for
the axis(es). Automatic transition from armed to active mode is indicated by the white armed mode annunciation
moving to the green active mode field and flashing for ten seconds.
A flashing yellow mode annunciation indicates either the loss of sensor (AHRS, ADC, IAU) or navigation data
(VOR, LOC, GPS) required to compute commands. When such a loss occurs, the system automatically begins to
roll the wings level or maintain the pitch angle, depending on the affected axis. The flashing annunciation stops
when the affected mode key is pressed or another mode for the axis is selected. After ten seconds, if no action is
taken, the flashing annunciation stops and the flight director enters the default mode for the affected axis.
Figure 7-4 Loss of VOR Signal
If the information required to compute a flight director mode becomes invalid or unavailable, the flight director
automatically reverts to the default mode for that axis. The flight director is automatically disabled if the attitude
information required to compute the default flight director modes becomes invalid or unavailable.
