Definition
An emergency maneuver flown when an aircraft encounters a sudden, severe change in wind speed or direction that threatens safe flight, particularly during takeoff or approach. The pilot applies maximum available thrust, establishes the recommended pitch attitude (typically toward the manufacturer's escape pitch target), retracts speedbrakes if extended, and maintains the existing aircraft configuration (does not change flap or gear position) until safely clear of the shear.
Plain English
A specific set of actions a pilot performs to fly out of a dangerous wind change. Push the throttles up, raise the nose to the recommended angle, leave the flaps and gear where they are, and climb away until the aircraft is clear of the bad air.
Context Anchor
Seen in wind shear training, cockpit warnings, takeoff briefings, and approach or landing procedures.
Derivation
“Wind” means moving air. “Shear” comes from an old word meaning “to cut.” In aviation, wind shear means wind that changes sharply over a short distance, almost like one layer of air is cutting across another. “Escape” means getting out of danger, which fits the pilot’s immediate action here.
Why Pilots Care
Wind shear can cause rapid loss of airspeed and altitude near the ground, and following the correct escape procedure is often the difference between recovery and an accident.
Grounding Statement
A wind shear escape is the pilot’s immediate climb-away response when the air suddenly stops helping the aircraft stay safely on its planned path.
Intuition Check
Do not think of “escape” as simply flying away when convenient. In this term, it means an immediate, practiced recovery maneuver started as soon as dangerous wind shear is detected or suspected.
Example Sentence 1
When the predictive wind shear warning sounded on short final, the captain called 'Go around, wind shear escape,' advanced the thrust levers to the firewall, and pitched up to the flight director's escape guidance.
Example Sentence 2
During the approach, the crew executed the wind shear escape when airspeed began to decay rapidly in the shear layer.
