Configuration. Flaps, landing gear, and other configuring devices can affect an airplane’s stall speed. Extension of flaps and/or landing gear in flight will increase drag. Flap extension will generally increase the lifting ability of the wings, thus reducing ... airplane’s stall speed. The effect of flaps on an airplane’s stall speed can be seen by markings on the airplane’s airspeed indicator, where the lower airspeed limit of the white arc (power-off stall speed with gear…
- Chapter 5: Aerodynamics of Flight › Load Factors › Load Factors and Stalling Speeds
Load Factors and Stalling Speeds Any aircraft, within the limits of its structure, may be stalled at any airspeed. When a sufficiently high AOA is imposed, the smooth flow of air over an airfoil breaks up and separates, producing ... loss of lift, which results in a stall. A study of this effect has revealed that an aircraft’s stalling speed increases in proportion to the square root of the load factor. This means that an aircraft with a normal…

markings: • White arc—commonly referred to as the flap operating range since its lower limit represents the full flap stall speed and its upper limit provides the maximum flap speed. Approaches and landings are usually flown at speeds within ... white arc. Figure 8-8. Single engine airspeed indicator (ASI). • Lower limit of white arc (VS0)—the stalling speed or the minimum steady flight speed in the landing configuration. In small aircraft, this is the power-off stall speed…

turn are also considered. The speed at which the critical angle of the relative wind is exceeded is the stall speed. Stall speeds are listed in the Airplane Flight Manual (AFM) or the pilot’s operating handbook (POH) and pertain ... certain conditions or aircraft configurations, e.g., landing configuration. Other specific operational speeds are calculated based upon the aircraft's stall speed in the landing configuration. Airspeed values specified in the AFM or POH may vary under different circumstances. Factors such…

understand that a stall is the result of exceeding the critical AOA, not of insufficient airspeed. The term “stalling speed” can be misleading, as this speed is often discussed when assuming 1G flight at a particular weight and configuration. Increased ... load factor directly affects stall speed (as well as do other factors such as gross weight, center of gravity, and flap setting). Therefore, it is possible to stall the wing at any airspeed, at any flight attitude…

Abbreviations and symbols. VS means the stalling speed or the minimum steady flight speed at which the airplane is controllable. VS0 means the stalling speed or the minimum steady flight speed in the landing configuration. VS1 means the stalling speed ... minimum steady flight speed obtained in a specific configuration. VSR means reference stall speed. VSRO means reference stall speed in the landing configuration. VSR1 means reference stall speed in a specific configuration. VSW means speed at which onset of natural…
