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.
A flashing yellow mode annunciation and annunciator light indicate loss of sensor
(ADC) or navigation data (VOR, LOC, GPS, VNAV) 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.
