Plain English Meaning

Using the throttle to choose how much engine power the airplane is producing. More power generally lets the airplane climb or speed up; less power lets it descend or slow down.

Full Definition

The pilot's use of the throttle (and propeller control, where fitted) to set engine output, which in turn governs airspeed and rate of climb or descent depending on how it is combined with pitch.

Context Anchor

Used in attitude flying when the pilot coordinates throttle changes with the airplane’s nose and wing position to control speed, climb, descent, or level flight.
