Definition
The phenomenon in jet aircraft where small movements of the flight controls produce larger or quicker airplane responses than a pilot transitioning from propeller airplanes is accustomed to, particularly at higher airspeeds and altitudes. It results from the jet's higher cruise speeds, cleaner aerodynamics, and the absence of propeller slipstream effects, all of which make the airplane respond more readily to control inputs.
Plain English
The jet reacts more to a given stick or yoke movement than a propeller airplane does, so the same input that felt normal before now produces a bigger, faster response.
Context Anchor
Encountered when transitioning to jet airplanes, especially when learning how control feel and aircraft response change at jet speeds.
Derivation
Sensitivity comes from a Latin root meaning “to feel.” In this aviation use, it is about how strongly the airplane seems to “feel” and respond to a pilot’s control input.
Why Pilots Care
Requires pilots to use smaller, smoother control inputs to prevent overcontrolling the aircraft.
Analogy
It is like switching from a car with heavy, slow steering to a sports car with quick, light steering. The same hand movement that felt normal before now turns the car much more sharply.
Intuition Check
Increased control sensitivity does not mean the controls are fragile or unsafe. It means the airplane responds more strongly to small control movements, so the pilot must make smaller inputs.
Example Sentence 1
During his first jet simulator session, the pilot noticed the increased control sensitivity and learned to fly the airplane with fingertip pressure rather than the firm inputs he used in the King Air.
Example Sentence 2
During high-speed cruise, the increased control sensitivity demanded precise handling to maintain smooth flight.
