3.2.5 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.
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 and the key on the GMC is disabled. A flashing yellow mode annunciation and
annunciator light indicate loss of sensor or navigation data required to compute
commands. When such a loss occurs, the system automatically begins to roll the wings
level (enters Roll Hold Mode) or maintain the pitch angle (enters Pitch Hold Mode),
depending on the affected axis. The flashing annunciation stops when the affected
mode key is pressed or another mode for the axis is selected. If after 10 seconds 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.
