What does A/C stand for in aviation terminology?

• A. Air Conditioning
• B. Aircraft
• C. Air Carrier
• D. Aircraft Carrier

Answer: (B)

In aviation shorthand, A/C is used to denote the Aircraft—the airplane itself. This makes communication when referring to the plane clear in logs, dispatch notes, and briefing rooms, without getting confused with parts or operators. The phrase Air Conditioning points to the cabin climate system, not the aircraft as a whole, so it’s a different concept within the same letters. Air Carrier refers to the airline or operator, and Aircraft Carrier is a naval ship, which wouldn’t fit civil aviation contexts. So the best match for A/C in this setting is Aircraft.
