V1 Decision speed; below V1 take-off is abandoned if the critical engine fails, aircraft can stop safely within remaining runway; above V1 take-off can be continued safely
V2 Minimum take-off safety speed
VA Design manoeuvring speed
VC Design cruise speed
VD Design diving speed
VMO Maximum (permitted) operating speed; re: MMO
VNE Never exceed speed
VR Rotation speed, speed at which pilot raises nose of aircraft during take-off
VS Stalling speed
VAR Variation
variable geometry Aircraft capable of changing wing-sweep in flight
variable pitch Propellor which can change pitch of its blades in flight
VASI Visual approach slope indicator

VDU Video display unit
also:  Visual display unit
vertrep Vertical replenishment
VFR Visual flight rules
VG Variable geometry
VHF Very high frequency
VHSIC Very high speed integrated circuits
VIP Very important person
