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 PFD.
With the flight director activated, the aircraft can be hand-flown to follow the path shown by the Command Bars.
Maximum commanded pitch (+20°/-15°) and bank (22°) 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
Pressing the FD or AP Key (when the flight director is not active) activates the flight director in default pitch/
roll modes. Pushing the
Go Around Switch or any fight director mode key activates the flight director in the
respective mode(s). The flight director may be turned off by pressing the
FD Key. The FD Key is disabled when
the autopilot is engaged.
COMMAND BARS
Upon activation of the flight director, Command Bars are displayed on the PFD as a single cue. The Command
Bars move together vertically to indicate pitch commands, and bank left or right to indicate roll commands.
If the attitude information sent to the flight director becomes invalid or unavailable, the Command Bars are
removed from the display. The Command Bars do not override the aircraft symbol.
