Flight Director Modes - Garmin G1000 Pilot's Manual

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 10 seconds.
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. 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 10 seconds, if no action is taken, the flashing annunciation stops.
The flight director is automatically disabled if the attitude information required to compute the default flight
director modes becomes invalid or unavailable.
