Which acronym stands for the device that provides electrical power on the ground?
Correct Answer:
GPU
Explanation:
The device that provides electrical power for an aircraft while it’s on the ground is called a Ground Power Unit, abbreviated as GPU. It supplies the aircraft with the necessary electrical power—often 400 Hz AC or DC power—so systems like lights, avionics, air conditioning, and preflight equipment can run without starting the engines or the APU. GPUs are used during preflight checks, maintenance, and boarding to keep everything powered safely on the ramp. The other terms shown aren’t devices that power the aircraft on the ground: FAA is the Federal Aviation Administration, the regulatory body; FLT is shorthand for flight; FAK isn’t a standard aviation power device. So GPU is the correct match for the ground power source.
