VELOCIDADES

 

V 1 the maximum speed in the takeoff at which the pilot must take the first action (e.g. apply brakes, reduce thrust, deploy speed brakes) to stop the aircraft within the accelerate-stop distance. V 1 also means the minimum speed in the takeoff, following a failure of the critical engine at V EF , at which the pilot can continue the takeoff and achieve the required height above the takeoff surface within the takeoff distance.

V 2 takeoff safety speed

V 2min minimum takeoff safety speed

V A design maneuvering speed

V B design speed for maximum gust intensity

V C design crusing speed

V D design diving speed

V DF /M DF demonstrated flight diving speed

V EF speed at which the critical engine is assumed to fail during takeoff

V F design flap speed

V FC M FC Maximum speed for stability characteristics. A speed that may not be less than a speed midway between maximum operating limit speed (V MO /M MO ) and demonstrated flight diving speed.

V FE maximum flap extended speed

V H maximum speed in level flight with maximum continuous power

V LE maximum landing gear extended speed

V LO maximum landing gear operating speed

V LOF lift-off speed

V MC minimum control speed with the critical engine inoperative

V MO M MO maximum operating limit speed

V MU minimum unstick speed

V NE never-exceed speed

V NO maximum structural crusing speed

V R rotation speed

V S stalling speed or the minimum steady flight speed at which the airplane is controllable

V S1 stalling speed or the minimum steady flight speed obtained in a specific configuration

V SO stalling speed or the minimum steady flight speed in the landing configuration

V TOSS takeoff safety speed for Category A rotorcraft

V X speed for best angle of climb - the speed at which an aircraft will gain the most altitude in the shortest distance

V Y speed for the best rate of climb - the speed at which an aircraft will gain the most altitude in the least amount of time
