1972 Flight 28 Dec. 946 The one distinct and inherent advantage possessed by the Hawker Siddeley aeroplane..is the ability to vector its thrust. The possibilities of VIFF (vectoring in forward flight) have been under examination for some time.

1981 F. K. Mason Harrier viii. 118 Initial investigations demonstrated that VIFF considerably enhanced the aircraft's potential in air combat.

B. v. intransitive.
