Definition
The upward aerodynamic force generated by an airplane's wings as air flows over and under them, opposing the weight of the aircraft and supporting it in flight. Wing lift varies with airspeed, angle of attack, wing shape, and air density, and it decreases as the airplane slows during the landing flare until the wings can no longer support the airplane and it settles onto the runway.
Plain English
The upward push the wings produce as air flows past them. It's what holds the airplane up. As the airplane slows down on landing, the wings make less and less of this upward push until the airplane gently touches down.
Context Anchor
Encountered during approach, roundout, flare, and touchdown discussions, where the pilot is managing a gradual loss of lift as the airplane slows near the runway.
Derivation
“Lift” comes from an old English word meaning to raise or make lighter. In aviation, it does not mean the wing is simply being pushed upward; it means the wing is producing an aerodynamic force because of how it moves through the air.
Why Pilots Care
Managing wing lift during the flare and touchdown prevents floating, ballooning, or hard landings.
Grounding Statement
As the airplane slows in the flare, the wings lose lifting force and the airplane settles toward the runway.
Intuition Check
Do not read “wing lift” as the physical wing moving upward. It means the lifting force produced by airflow over the wing.
Example Sentence 1
As the airplane slowed in the flare, wing lift decreased and the main wheels gently touched down on the runway.
Example Sentence 2
If wing lift stays high after initial contact the airplane may float back into the air and require another flare.
