Definition
The throttle control pushed all the way forward to the stop, commanding the engine to produce its maximum available power for the current conditions.
Plain English
Throttle pushed completely forward to ask the engine for everything it can give right now.
Context Anchor
Used during takeoff, climb, recovery from low energy, and situations where the pilot needs maximum available power.
Derivation
Throttle comes from an old word connected with the throat or narrowing a passage. In an engine, the throttle controls how much air and fuel can flow in, so “full throttle” means that control is fully opened for maximum available power.
Why Pilots Care
Applying full throttle at the correct moment prevents irreversible deceleration or sink rate while avoiding over-boost or engine damage in critical phases of flight.
Intuition Check
Do not assume full throttle means the airplane will immediately speed up or climb. It only means the pilot has commanded maximum available engine power; the airplane’s actual response depends on speed, pitch, drag, weight, and air density.
Example Sentence 1
Sensing the sink rate increasing on short final, the pilot lowered the nose and applied full throttle to arrest the descent.
Example Sentence 2
When the aircraft began to sink on short final, the instructor directed full throttle to restore climb performance.
