  2. Stall (fluid dynamics) - Wikipedia

    en.wikipedia.org/wiki/Stall_(fluid_dynamics)

    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]

  3. V speeds - Wikipedia

    en.wikipedia.org/wiki/V_speeds

    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

  4. Maneuvering speed - Wikipedia

    en.wikipedia.org/wiki/Maneuvering_speed

    In aviation, the maneuvering speed of an aircraft is an airspeed limitation at which the full deflection of the controls can be made at without risking structural damage. [1] The maneuvering speed of an aircraft is shown on a cockpit placard and in the aircraft's flight manual but is not commonly shown on the aircraft's airspeed indicator. In ...

  5. Coffin corner (aerodynamics) - Wikipedia

    en.wikipedia.org/wiki/Coffin_corner_(aerodynamics)

    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, making it very difficult to keep an airplane in stable flight. Because the stall speed is the minimum speed required to maintain level flight, any reduction ...

  6. Falling leaf - Wikipedia

    en.wikipedia.org/wiki/Falling_leaf

    A falling leaf is performed by first cutting the throttle and possibly deploying the speed brakes, if available, allowing the aircraft's speed to drop to the point where the relative wind can no longer hold the plane aloft, called the "stall speed." As the speed drops, the pilot holds the plane as level as possible in both the longitudinal ...

  7. Van's Aircraft RV-9 - Wikipedia

    en.wikipedia.org/wiki/Van's_Aircraft_RV-9

    The RV-9 was designed from the start as a two-place, side-by-side, touring aircraft and as such it forgoes the aerobatic capabilities and the lighter handling for more stability and economy. As such the design horsepower is 118–160 and the prototype was flown with a Lycoming O-235 powerplant of 118 hp (88 kW) as a proof-of-concept for the ...

  8. Flight control modes - Wikipedia

    en.wikipedia.org/wiki/Flight_control_modes

    Two aircraft manufacturers produce commercial passenger aircraft with primary flight computers that can perform under different flight control modes. The most well-known is the system of normal, alternate, direct laws and mechanical alternate control laws of the Airbus A320-A380. [3]
