PA stands for which term?

• A. Passenger
• B. Protective Breathing Equipment
• C. Principal Operations Inspector
• D. Public Address

Answer: (D)

In aviation, PA refers to the Public Address system—the onboard system used to make announcements to passengers and crew. This includes safety briefings, flight information, boarding or service notices, and any urgent instructions during the flight. It’s the standard term for the cabin announcements you hear and make, which is why it’s the correct choice. The other options don’t fit because they refer to people (Passenger), equipment unrelated to communications (Protective Breathing Equipment), or a regulatory role (Principal Operations Inspector), none of which describe a onboard announcement system.
