V-Speeds
A term you will have come across is V speed, probably in one of it's many forms. There is V1, Vr, Vso and so on. These speed are different speed for the aircraft you are flying. Below are the different V speeds around, with a small explanation.
V1 - takeoff decision speed V2 - takeoff safety speed V2min - minimum takeoff safety speed Va - design maneuvering speed Vb - design speed for maximum gust intensity Vc - design cruise speed Vd - design dive speed Vdf - demonstration dive speed Vf - design flap speed Vfc - maximum speed for stability characteristics Vfe - maximum flap-extended speed Vh - maximum speed in level flight with maximum continuous power Vle - maximum landing-gear extended speed Vlo - maximum landing-gear operating speed Vlof - lift-off speed Vmc - minimum control speed Vmca - minimum control speed with critical engine out of ground effect Vmcg - minimum control speed with critical engine out during takeoff run Vmo - maximum operating speed Vmu - minimum unstick speed Vne - Never-exceed speed Vno - maximum structural cruise speed Vr - rotation speed Vref - reference speed for final approach, normally 1.3Vso Vs - stall speed Vso - stall speed in landing configuration Vs1 - minimum steady flight speed in specific configuration Vsse - minimum safe single-engine speed Vtoss - takeoff safety speed for Category A rotorcraft Vx - best angle-of-climb speed Vxse - best single-engine angle-of-climb speed Vy - best rate-of-climb speed Vyse - best single-engine rate-of-climb speed |
