Plain English Meaning
An airplane with engines that work like a small jet inside, but instead of pushing the airplane with jet exhaust, the engine spins a propeller that pulls the airplane through the air.
Full Definition
An airplane powered by one or more turbine engines that drive propellers through a reduction gearbox. The turbine produces shaft power, which turns the propeller; the propeller, not jet thrust, provides nearly all of the airplane's forward thrust.
Context Anchor
Seen when comparing airplane types and when transitioning to higher-performance single-engine or multiengine airplanes.
