Angle of Attack (AoA)

Formal Definition

The angle between the chord line of an airfoil and the direction of the oncoming air (relative wind).

A critical safety metric; exceeding the 'Critical Angle of Attack' results in an aerodynamic stall, regardless of airspeed.

"The pilot monitored the AoA indicator to ensure the aircraft remained above the stall margin during the slow-flight maneuver."

Confused with 'Pitch Angle'; Pitch is relative to the horizon, AoA is relative to the wind.

Airfoil Aerodynamic Stall Chord Line

AoA is the angle between the chord line and what?

Can a plane stall at high speed?
