Barry this will happen occasionally when an a/c fitted with
servo tabs is not in flight. the control surfaces on these a/c
is operated by a small servotab operated by the cockpit
controls. This servotab is located on the trailing edge of the
flight control and uses the slipstream to operate the control
surface. In other words, the pilots do not control the surfaces
directly, they merely operate the servotabs which in turn use
the slipstream to move the control surfaces themselves.
