Definition
A small, deliberate push or pull on the control yoke applied to the elevator to correct an unwanted climb or descent and return the aircraft to level flight. The pressure is held just long enough to stop the trend shown on the vertical speed indicator and altimeter, then released or relaxed as the aircraft settles back to the desired altitude.
Plain English
A gentle push or pull on the yoke to fix a small climb or descent and bring the aircraft back to level.
Context Anchor
Seen during instrument straight-and-level flight when the vertical speed indicator shows the airplane is climbing or descending.
Derivation
Corrective comes from the Latin corrigere, meaning to set right or straighten. Elevator pressure refers to the force applied through the yoke that moves the elevator control surface. Together the phrase means a force applied to set the pitch right.
Why Pilots Care
Prevents gradual altitude loss or gain that can lead to disorientation or airspace conflicts.
Intuition Check
“Pressure” here does not mean air pressure, and “elevator” is not a lift in a building. It means hand force on the flight control that moves the airplane’s tail control surface.
Example Sentence 1
When the VSI showed a 100-foot-per-minute climb, the pilot applied light corrective elevator pressure to return to assigned altitude.
Example Sentence 2
Smooth corrective elevator pressure keeps the aircraft in straight-and-level flight without overcontrolling the yoke.
