V Speeds Flashcards
Hammer Home All of the V Speeds
Vso
Stall speed in landing configuration: the calibrated power-off stalling speed or the minimum steady flight speed at which the airplane is controllable in the landing configuration.
Vs1
Stall speed clean, or in a specified configuration; the calibrated power-off stalling speed or the minimum steady flight speed at which the airplane is controllable in a specified configuration
Vy
Best rate of climb speed; the calibrated airspeed at which the airplane will obtain the maximum increase in altitude per unit of time. (Normally decreases slightly with altitude)
Vx
Best angle of climb speed; the calibrated airspeed at which the airplane will obtain the highest altitude in a given horizontal distance. (Normally increases with altitude)
V(LE)
Maximum landing gear extension speed; the maximum calibrated airspeed at which the airplane can be safely flown with the landing gear extended.
V(LO)
Maximum landing gear operating speed; the maximum calibrated airspeed at which the landing gear can be safely extended or retracted.
Va
Maneuvering Speed: the calibrated design maneuvering airspeed. This is the maximum airspeed at which the load limit can be imposed (either by turbulence, gusts or the full deflection of the control surfaces) without causing structural damage.
V(FE)
Maximum flap extension speed; the highest calibrated airspeed permissible with the wing flaps in a prescribed extended position
V(NO)
Normal operating speed (also maximum structural cruising speed); the maximum calibrated airspeed for normal operation. The speed above which exceeding the limit load factor may cause permanent deformation of the airplane structure.
V(NE)
Never exceed speed: the calibrated airspeed which should never be exceeded. If flight is attempted above this speed, structural damage or structural failure may result.
