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 or navigation data required
to compute commands.
