Which acronym stands for First Officer?

• A. FO
• B. FAA
• C. FAR
• D. GPU

Answer: (A)

FO is the acronym used for First Officer. In aviation, the flight crew typically consists of a Captain and a First Officer, with the First Officer serving as the co-pilot who assists with flying, performing checklists, and stepping in for the Captain when needed. In everyday cockpit language, you’ll see or hear “FO” to refer to that crew role, as a concise shorthand in flight plans, logs, and communications. The other options point to different things: FAA is the Federal Aviation Administration, the U.S. regulator; FAR stands for Federal Aviation Regulations, the rules governing flight operations; GPU means Ground Power Unit, a device that provides electrical power on the ground. So FO directly names the First Officer, while the others are unrelated terms.
