Plain English Meaning
Small movements of the controls that raise or lower the nose to keep the airspeed where it should be.
Full Definition
Adjustments made to the airplane's nose-up or nose-down attitude using elevator input to control airspeed during a maneuver.
Context Anchor
Used in the steep spiral, where the airplane is descending and the pilot must keep the airspeed under control while turning around a ground reference point.
Derivation
Pitch' originally referred to the up-and-down rocking of a ship's bow. Aviation borrowed the term for the same motion of an aircraft's nose. A 'correction' is simply a fix applied when something has drifted off target.
Why Pilots Care
Proper airspeed prevents the airplane from stalling or exceeding its speed limits during the high-bank descent.
Intuition Check
Do not read pitch here as sound or steepness of a line. In this context, pitch means the airplane’s nose position: nose up or nose down.
Example Sentence 1
During the steep spiral, the pilot made small pitch corrections to hold the target airspeed as the bank angle varied with the wind.
Example Sentence 2
To hold 80 knots throughout the turn, small pitch corrections were applied as the descent continued.
