- 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.Relationship between load factor and stalling speed.

reference speed — The target speed by airline pilots on short finals. This is referred to as VREF + 5, VREF + 10, or VREF + 15 on various stages of the approach. VREF is factored on the stalling speed (1.3 × VSO ) and so varies with aircraft weight. VSO stands for … Aviation dictionary
