A/C stands for what?

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

Answer: (D)

In aviation shorthand, A/C is commonly used to mean the aircraft itself. This shorthand pops up in dispatch notes, flight plans, and ATC or maintenance communications when referring to the plane involved. So the best answer is “Aircraft,” because that is the standard aviation meaning for A/C in operational contexts. The other options don’t fit typical aviation usage: air conditioning refers to the environmental system, not the aircraft being discussed; an air controller is a person (air traffic controller) rather than the aircraft; and an aircraft carrier is a naval term, not relevant to plain aviation shorthand.
