vorticity (meteorology). Turning of the atmosphere. Vorticity may be embedded in the total air-flow and not readily identified by a flow pattern. See absolute vorticity, negative vorticity, positive vorticity, and relative vorticity. VOT (VOR test signal). A ground facility which emits a test signal to check VOR receiver accuracy. Some VOTs are available to the user while airborne, and others are limited to ground use only. 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 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 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 — the stalling speed or the minimum steady flight speed at which the airplane is controllable. VS0 — the stalling speed or the minimum steady flight speed in the landing configuration. VS1 — the stalling speed or the minimum steady flight speed obtained in a specific configuration. VTOSS — takeoff safety speed for Category A rotorcraft. VX — speed for best angle of climb. VY — speed for best rate of climb. V1 — takeoff decision speed (formerly denoted as critical engine failure speed). V2 — takeoff safety speed. V2min — minimum takeoff safety speed. VSWR (voltage standing-wave ratio). A measure of reflected energy in an electrical transmission line such as a waveguide or a coaxial cable. VSWR is the ratio of a voltage maximum to an adjacent voltage minimum. |
