COJ stands for what?

COJ stands for what?

• A. Captain Onboard Jump Seat
• B. Captain Observer Jumpseat
• C. Commanding Officer Jumpseat
• D. Chief Observer Jumpseat

Answer: (B)

In aviation acronyms, letters map to a role, a function, and a location. COJ breaks into Captain, Observer, Jumpseat, so it stands for Captain Observer Jumpseat. This labeling pattern is common for jumpseat designations, naming who sits there and what seat is involved. That’s why this is the best fit: the word order directly reflects a captain’s role, the observer’s function, and the jumpseat itself, which is how airline terminology typically organizes these designations. The other options use less standard terms (like Onboard, Chief, or Commanding Officer) or don’t align with the typical captain/observer jumpseat wording, so they don’t fit as neatly.
