Definition
Applying flight control inputs that are larger, faster, or more aggressive than the situation requires, producing an exaggerated airplane response that the pilot must then correct, often leading to a series of overcorrections in the opposite direction.
Plain English
Pushing, pulling, or moving the controls too much or too quickly, so the airplane reacts more than you wanted and you end up chasing the correction back and forth.
Context Anchor
Seen during takeoff and climb when the pilot is holding runway direction, raising the nose, or correcting for wind after liftoff.
Derivation
Built from 'over-' (too much) and 'control.' The hyphenated form signals the specific meaning of using too much control input, rather than 'overcontrol' as a general idea of dominating something.
Why Pilots Care
Over-control creates pilot-induced oscillations that can lead to loss of directional control, runway excursions, or stall during the most critical phase of flight.
Analogy
It is like steering a car by making big, quick turns of the wheel instead of small corrections; the car starts wandering because each correction is too much.
Intuition Check
Do not assume that stronger corrections mean better control. In this context, good control usually means small, smooth inputs that stop when the airplane is doing what you want.
Example Sentence 1
During the takeoff roll, the student tended to over-control the rudder, causing the nose to swing left and right across the centerline.
Example Sentence 2
Light crosswinds demand gentle inputs; any tendency to over-control the rudder will swing the nose back and forth.
