OVERPOWERING AUTOPILOT SERVOS
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 are 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.
