Which two documents must be current on board to legally operate a U.S.-registered aircraft?

• A. The aircraft's airworthiness certificate and registration
• B. The pilot's medical certificate and government ID
• C. The flight plan and insurance
• D. The maintenance logbook and airworthiness certificate

Answer: (A)

The main idea being tested is which documents are required to be on board a U.S.-registered aircraft to fly legally. The two that must be current and on board are the airworthiness certificate and the aircraft’s registration. The airworthiness certificate confirms the airplane conforms to its approved design and is in a condition for safe operation, and it must be kept on board and readily visible. The registration certificate proves ownership and that the aircraft is properly registered; it also must be current and on board so authorities can verify the aircraft’s identity and registration status. Other items mentioned aren’t required to be on the aircraft for legal operation in the same way. A pilot’s medical certificate is essential for the pilot’s ability to fly, but it’s carried by the pilot rather than required to be on the aircraft at all times. Flight plans and insurance aren’t universally required for domestic flights, and maintenance logbooks live with the aircraft and aren’t required to be carried on board during flight.
