Definition
The specific control input a pilot applies to return an instrument indication to its desired value after a deviation has been detected. In the context of altimeter use during straight-and-level flight, the corrective technique is a small, smooth pitch adjustment using the elevator control, accompanied by a trim change as needed, to restore the assigned altitude.
Plain English
The action you take to fix a deviation once you've spotted it on the instruments — typically a small, smooth control input that brings the airplane back to where it should be.
Context Anchor
Seen in instrument flying when the altimeter shows the aircraft drifting away from the altitude the pilot is trying to hold.
Derivation
From Latin 'corrigere,' meaning 'to make straight' or 'to put right,' and Greek 'tekhnē,' meaning 'skill' or 'method.' Together it captures the idea of a learned skill for putting something back to where it should be.
Why Pilots Care
Instrument flying is a constant cycle of detecting small deviations and correcting them before they grow. A poorly applied correction — too large, too abrupt, or in the wrong direction — usually creates a bigger problem than the original deviation. Smooth, measured corrective technique is the foundation of precise instrument flight.
Intuition Check
Corrective technique does not mean any action that seems to help. It means a deliberate, measured method that fixes the specific error without creating a new one.
Example Sentence 1
When the altimeter showed the aircraft 50 feet low, the pilot applied a gentle corrective technique with slight back pressure on the elevator to return to the assigned altitude.
Example Sentence 2
During the level-off check, the student used the corrective technique of adding slight power to stop a slow altitude loss.
