- 'V-speeds' Shorthand notation of significant speeds within an aircraft's flight envelope (see table).
- variable geometry Capable of grossly changing shape in flight, especially by varying sweep of wings.
- variable pitch Propeller with its blades held in rotary bearings in the hub, so that pitch (of all blades in unison) can be altered in flight. See constant speed; compare ground- and flight-adjustable pitch.
- VDU Video (or visual) display unit.
- vectored Capable of being pointed in different directions.
- vertrep Vertical replenishment.
- VFR Visual flight rules.
- VHF Very high frequency.
- VLF Very low frequency (area-coverage navaid).
- VMS Vehicle management system.
- VOR VHF omnidirectional range (network of VHF radio beacons each providing to/from bearing).
- vortex generators Small blades attached to wing and tail surfaces to energise local airflow and improve control.
- vortillon Short-chord fence (particularly on MD-80 series) ahead of and below leading-edge.
- VSI Vertical speed (climb/descent) indicator.
- V/STOL Verical/short take-off and landing.
