In the context of this discussion, “overpowering” refers to any pressure or force
applied to the pitch controls when the autopilot is engaged. A small amount of
pressure or force on the pitch controls can cause the autopilot automatic trim to run to
an out-of-trim condition. Therefore, any application of pressure or force to the controls
should be avoided when the autopilot is engaged.
Overpowering the autopilot during flight will cause the autopilot’s automatic trim to
run, resulting in an out-of-trim condition or cause the trim to hit the stop if the action
is prolonged. In this case, larger than anticipated control forces may be required after
the autopilot is disengaged.
The following steps should be added to the preflight check:
1)
Check for proper autopilot operation and ensure the autopilot can be
overpowered.
2)
Note the forces required to overpower the autopilot servo clutches.
3.1.12 FLIGHT DIRECTOR OPERATION
NOTE:
Refer to the Installation Manual section for AFCS setup information.
The flight director function provides pitch and roll commands to the pilot and
autopilot, which are displayed on the PFD Page. With the flight director active, the
aircraft can be hand-flown to follow the path shown by the Command Bars. The Flight
Director has the following maximum commands: pitch (-15°, +20°) and roll (30°)
angles.
