stalling speed

The basic stalling speed is the speed below which a clean aircraft of stated weight, with the engines throttled back, can no longer maintain a straight and level flight because the wing is stalling. Factors that affect the basic stalling speed are the weight, load factor, power, and slipstream and changes in the configuration (undercarriage up/down, flaps out/in, external stores, etc.). The stalling angle of an aircraft is fixed but the stalling speed is dependent on these factors.
