Propeller slipstream reduces the stall speed by energizing the flow over the wings. [26]: 61 Speed definitions vary and include: 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. [27]
Stall speed or minimum steady flight speed for which the aircraft is still controllable. [7] [8] [9] V S 0: Stall speed or minimum flight speed in landing configuration. [7] [8] [9] V S 1: Stall speed or minimum steady flight speed for which the aircraft is still controllable in a specific configuration. [7] [8] V S R: Reference stall speed. [7 ...
V A is the design maneuvering speed and is a calibrated airspeed.Maneuvering speed cannot be slower than and need not be greater than V c. [4]If is chosen by the manufacturer to be exactly the aircraft will stall in a nose-up pitching maneuver before the structure is subjected to its limiting aerodynamic load.
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.
Threshold speed is calculated as 1.3 times stall speed V s0 or 1.23 times stall speed V s1g in the landing configuration at maximum certificated landing mass. [1]: Table II-5-1-2 Aircraft approach categories do not change during day-to-day operation.
An aircraft in cruise flight is typically speed stable. If speed increases, drag increases, which will reduce the speed back to equilibrium for its configuration and thrust setting. If speed decreases, drag decreases, and the aircraft will accelerate back to its equilibrium speed where thrust equals drag.
The airspeed at which the aircraft stalls varies with the weight of the aircraft, the load factor, the center of gravity of the aircraft and other factors. However, the aircraft normally stalls at the same critical angle of attack, unless icing conditions prevail. The critical or stalling angle of attack is typically around 15° - 18° for many ...
