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.
