Definition
The point on a wing or airfoil where the total lift force is considered to act. Its position shifts forward or aft along the chord as angle of attack changes, and its location relative to the center of gravity affects the aircraft's pitching tendency.
Plain English
Lift is spread across the whole wing, but you can think of it as one upward push acting at a single point. That point is the center of lift. Where it sits on the wing changes as the wing's angle to the air changes.
Context Anchor
Seen in aerodynamics and icing discussions, especially when a diagram shows how ice changes the airflow and shifts where lift acts on the airfoil.
Derivation
From the everyday word 'center,' meaning the middle or balance point, and 'lift,' the upward aerodynamic force. Together: the balance point of the lifting force.
Why Pilots Care
Icing can shift the center of lift, altering stability and increasing stall risk if not recognized.
Analogy
Imagine balancing a ruler on one finger. The ruler's weight is spread along its length, but it balances at one point. The center of lift is that same idea — the single point where the wing's total lift effectively acts.
Grounding Statement
Picture the wing as having one main upward push point; ice can change the wing shape and move that push point.
Intuition Check
Do not assume center of lift means the physical middle of the wing. It means the effective point where the wing’s lifting force acts.
Example Sentence 1
Ice accumulation on the leading edge disrupted airflow over the wing and shifted the center of lift, contributing to the unusual pitch behavior the crew reported.
Example Sentence 2
The pilot monitors angle of attack because it directly influences the location of the center of lift.
