It actually _does_ happen when you disconnect the autopilot, in some
aircraft. The purpose of the autopilot is not to relieve control
pressure, it is to fly the aircraft. In aircraft that use trim for
the autopilot, the aircraft may be stable when you turn the autopilot
off. However, in aircraft that directly manipulate the controls with
the autopilot, the aircraft may suddenly change attitude when the AP
is shut off, if the AP has been compensating for something (such as an
engine failure) while it has been operating. This has caused
accidents.

You have no idea what you're talking about, fjukktard.
