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] The zero-thrust stall speed at the most extended landing flap setting. [26]: 8 V S1: The stall speed or minimum steady flight speed obtained in a ...
When the stall speed is reached, the plane will lose lift and begin to fall. Due to the low speed and high angle of attack (the angle of the wings to the relative wind), the aircraft loses its boundary layer, making the control surfaces barely responsive to pilot inputs. Therefore, the controls are usually pushed to their maximum limit to get ...
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 ...
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.
The British Auster WW2 reconnaissance aircraft had a placarded stall speed of 24 knots (44 km/h; 28 mph), [5] but that was merely the speed at which its control surfaces lost authority. As reported in many personal accounts by the pilots in their memoirs, the speed at which the aircraft would actually stall was 24 miles per hour (39 km/h).
Though school hours in California might range from about 7 a.m. to 4 p.m., Olsen said drivers should still be cautious when passing by a school zone because after-school programs can last until 6 p.m.

An increase in weight increases the stall speed of the aircraft. Therefore, the landing approach speed increases as the aircraft's weight increases. The kinetic energy ( 1 / 2 mV 2) that has to be dissipated to stop an aircraft is a function of the mass of the aircraft and the square of its speed at touchdown. The kinetic energy ...
