Definition
Engine thrust whose direction can be deliberately redirected by the pilot, rather than acting only along the aircraft's longitudinal axis. This is achieved by rotating or deflecting the engine exhaust (or the engine itself) so that the thrust force can point downward, rearward, or somewhere in between, allowing the aircraft to hover, take off vertically, or perform short takeoffs and landings.
Plain English
The pilot can aim the engine's push in different directions instead of just straight back. By pointing it down, the aircraft can lift straight up; by pointing it back, the aircraft flies forward normally.
Context Anchor
Seen in discussions of thrust, aircraft control, and aircraft designs that can redirect engine force for takeoff, landing, or maneuvering.
Derivation
From 'vector,' a term borrowed from mathematics and physics meaning a quantity with both size and direction. To 'vector' thrust is to give it a chosen direction, not just a magnitude.
Why Pilots Care
It allows an aircraft to use engine power for lift, braking, or tight maneuvering instead of only forward speed.
Analogy
It is like aiming a garden hose. The water has force, but where you point the hose determines which way that force acts.
Grounding Statement
Picture the engine’s push as an arrow: vectored thrust means the arrow can be pointed in a selected direction instead of staying fixed straight back.
Intuition Check
Do not read “vectored” as meaning ATC is giving the aircraft headings. Here it means the thrust itself is being aimed in a particular direction.
Example Sentence 1
The Harrier uses vectored thrust to take off from short runways and to hover over a landing pad.
Example Sentence 2
During takeoff the nozzles rotated downward so vectored thrust lifted the aircraft straight up.
