Plain English Meaning

A motor that runs on electricity from the aircraft's battery and generator/alternator, rather than on hydraulic fluid pressure or engine power. In landing gear, it provides the muscle that physically moves the wheels into and out of their wells.

Full Definition

A motor powered by the airplane's electrical system that converts electrical energy into mechanical motion, used in some retractable landing gear systems to drive the gear up and down through a series of gears, shafts, or screw jacks.

Context Anchor

Seen in landing gear system descriptions when the gear is moved by electrical rather than only by ’s hand or by equipment.
