V S: Stall speed: the speed at which the airplane exhibits those qualities accepted as defining the stall. [26]: 8 V S0: The stall speed or minimum steady flight speed in landing configuration.

The Ruppert Archaeopteryx has a certified stall speed of 30–39 kilometres per hour (19–24 mph). [3] The Vought XF5U can fly as slow as 32 kilometres per hour (20 mph). [4] The Tapanee Pegazair-100 stall speed is 45 kilometres per hour (28 mph). The Zenith STOL CH 701 and ICP Savannah both have stall speeds of 48 kilometres per hour (30 mph).

Wing loading is a useful measure of the stalling speed of an aircraft. Wings generate lift owing to the motion of air around the wing. Larger wings move more air, so an aircraft with a large wing area relative to its mass (i.e., low wing loading) will have a lower stalling speed.
The minimum such speed is the stall speed, or V SO. The indicated airspeed at which a fixed-wing aircraft stalls varies with the weight of the aircraft but does not vary significantly with altitude. At speeds close to the stall speed the aircraft's wings are at a high angle of attack. At higher altitudes, the air density is lower than at sea level.
Table II-5-1-2 Aircraft approach categories do not change during day-to-day operation. To change an aircraft's category, an aircraft must be re-certified with a different maximum landing mass. [1]: II-5-1-3 Pilots may not use a lower category than the one certified, but may choose to use a higher category for higher speed approaches. [2]
