Which abbreviation stands for First Officer?

• A. FAA
• B. FO
• C. FAK
• D. FAR

Answer: (B)

FO is the common shorthand for First Officer, the flight deck co-pilot who assists the Captain. In crew rosters, flight decks, and training materials you’ll see FO used to identify the second-in-command on a aircraft. The other abbreviations refer to something else: FAA is the Federal Aviation Administration, the U.S. aviation regulator; FAR stands for Federal Aviation Regulations, the rules governing flight; FAK isn’t a standard aviation abbreviation for a pilot role. Recognizing FO as First Officer helps you quickly understand who’s in the second-in-command position on a flight and how the Captain and FO share duties, with roles like Pilot Flying and Pilot Monitoring as needed.
