A fixed-wing aircraft can be made to stall in any pitch attitude or bank angle or at any airspeed but deliberate stalling is commonly practiced by reducing the speed to the unaccelerated stall speed, at a safe altitude. Unaccelerated (1g) stall speed varies on different fixed-wing aircraft and is represented by colour codes on the airspeed ...
The steepness of the high flow part of a constant speed line is due to the effects of compressibility. The position of the other end of the line is located by blade or passage flow separation. There is a well-defined, low-flow boundary marked on the map as a stall or surge line, at which blade stall occurs due to positive incidence separation.
Steady flight, unaccelerated flight, or equilibrium flight is a special case in flight dynamics where the aircraft's linear and angular velocity are constant in a body-fixed reference frame. [1] Basic aircraft maneuvers such as level flight, climbs and descents, and coordinated turns can be modeled as steady flight maneuvers. [ 2 ]
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 S R 0: Reference stall speed in landing configuration. [7] V S R 1: Reference stall speed in a specific configuration. [7] V SW: Speed at which the stall warning will occur. [7] V TOSS
Coffin corner (also known as the aerodynamic ceiling [1] or Q corner) is the region of flight where a fast but subsonic fixed-wing aircraft's stall speed is near the critical Mach number, at a given gross weight and G-force loading. In this region of flight, it is very difficult to keep an airplane in stable flight.
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).
Spin — an aggravated stall and autorotation For fixed-wing aircraft , autorotation is the tendency of an aircraft in or near a stall to roll spontaneously to the right or left, leading to a spin (a state of continuous autorotation).
The falling leaf is often used as a training maneuver, teaching the pilot to control the plane during a stall and helping beginners to overcome the fear that happens when a plane stalls unexpectedly. It is generally performed from a low-speed, straight, level stall, to avoid the buffeting, departure from the normal flightpath, and flat spin ...
