In common aviation shorthand, A/C stands for which term?

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

Answer: (B)

In aviation shorthand, A/C is used to mean aircraft—the airplane itself. This abbreviation shows up in flight operations, maintenance logs, and dispatch notes where quick, compact references are needed. When someone writes A/C type, A/C tail number, or similar phrases, they’re talking about the aircraft, not other things. Air conditioning is not typically the intended meaning in this context, and the other options—Alternate Carrier and Aircraft Carrier—aren’t standard aviation shorthand for everyday flight operations; the latter refers to a naval ship, not something used in civilian aviation terminology.
