Definition#
Stall speed is the minimum airspeed at which an aircraft can sustain level flight for a given weight, configuration (flaps, gear), and load factor. Below stall speed, the wing exceeds its critical angle of attack and lift decreases sharply.
Why It Matters Operationally#
Stall speed directly determines approach and landing speeds, takeoff rotation speeds, and maneuvering limits. It increases with weight and load factor (bank angle, turbulence).
