Definition
The speed at which a pilot returns the aircraft to a desired flight parameter (such as altitude, heading, or airspeed) after a deviation has been detected. It describes how aggressively the correction is applied, not the size of the correction itself.
Plain English
How quickly you bring the airplane back to where it should be after it has drifted off. A fast rate of correction means a firm, quick fix; a slow rate means a gentle, gradual one.
Context Anchor
Seen when using the Vertical Speed Indicator to correct an altitude deviation during instrument flying.
Why Pilots Care
On instruments, an over-aggressive rate of correction causes overshooting and chasing the needles, while too slow a rate lets deviations grow. Matching the rate of correction to the size of the deviation is a core instrument flying skill.
Analogy
If you are driving slightly out of your lane, you do not yank the wheel; you make a smooth correction at the right rate. Altitude corrections work the same way.
Intuition Check
Do not read “rate of correction” as whether the correction is right or wrong. Here, “rate” means how fast the correction is being made.
Example Sentence 1
When the VSI showed a 200-foot deviation, the pilot used a small rate of correction to ease back to altitude rather than pitching up sharply.
Example Sentence 2
A faster rate of correction on the VSI helps the pilot anticipate when the aircraft will reach the desired climb rate.
