Transcription of V-speeds
1 V-speeds A series of designators used by the FAA and listed in 14 CFR 1 to describe certain flight conditions. VA Design maneuvering speed VB Design speed for maximum gust intensity VC Design cruising speed VD Design diving speed VDF/MDF Demonstrated flight diving speed VF Design flap speed VFC/MFC Maximum speed for stability characteristics VFE Maximum flaps 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 with the critical engine inoperative VMO/MMO Maximum operating limit speed VMU Minimum unstick speed VNE Never-exceed speed VNO Maximum structural cruising speed VR Rotation speed VS Stalling speed or minimum steady flight speed at which the aircraft is controllable VS O Stalling speed or minimum steady flight speed in the landing configuration VS1 Stalling speed or minimum
2 Steady flight speed obtained in a specific configuration VTOSS Take-off safety speed for Category A rotorcraft VX Speed for best angle of climb VY Speed for best rate of climb V1 Take-off decision speed (formerly denoted as critical engine failure speed).
