Which acronym refers to the Ground Power Unit?

• A. Flight
• B. GPU
• C. FAA
• D. FAM

Answer: (B)

The main idea here is recognizing what the acronym GPU stands for in aviation operations. A GPU, or Ground Power Unit, is an external source of electrical power used to power an aircraft on the ground without running its engines or onboard systems. That makes it the term that matches “Ground Power Unit.” The other options don’t refer to this device: Flight isn’t a power-supply acronym; FAA stands for the Federal Aviation Administration, the regulatory body; FAM typically refers to a Flight Attendant Manual or similar, not a power unit. So GPU is the correct acronym because it specifically denotes the Ground Power Unit used to provide ground power to aircraft.
