AUTOMATIC FLIGHT CONTROL SYSTEM
7.2 FLIGHT DIRECTOR OPERATION
The flight director function provides pitch and roll commands to the AFCS and displays them on the PFDs.
With the flight director active, the aircraft can be hand-flown to follow the path shown by the Command Bars.
Maximum commanded pitch (-15°, +25°) and roll (25°) angles, vertical acceleration, and roll rate are limited to
values established during AFCS certification. The flight director also provides commands to the autopilot.
ACTIVATING THE FLIGHT DIRECTOR
An initial press of a key listed in Table 7-1 (when the flight director is not active) activates the pilot-side flight
director in the listed modes. The flight director may be turned off and the Command Bars removed from the
displays by pressing the
FD
Key again. The
FD
Key is disabled when the autopilot is engaged.
