Which term is used to designate the Aircraft abbreviation?

• A. A/C
• B. AO
• C. AED
• D. ATC

Answer: (A)

In aviation writing, A/C is the standard shorthand for Aircraft. It appears on charts, maintenance documents, load sheets, and flight plans to indicate the airplane itself or equipment related to the aircraft. The other terms don’t serve that purpose: AO isn’t a recognized abbreviation for Aircraft, AED usually stands for automated external defibrillator, and ATC means Air Traffic Control, a separate role in airspace management. So A/C is the correct designation because it is the internationally understood abbreviation used to denote the aircraft.
