Which document authorizes radio communications on the aircraft?

• A. OPS Manual
• B. Radio License
• C. Flight Plan
• D. ARC

Answer: (B)

Radio transmissions from an aircraft require a license specifically for the radio station. This authorization is issued by the national communications or aviation authority and covers the aircraft’s radio equipment, including what frequencies may be used, transmission power, and the designated call sign. Without this license, operating the onboard transmitter would be illegal and could lead to penalties, and ATC communications would not be legally protected. Other documents serve different purposes: the operations manual outlines procedures for the operator, not authorization to transmit; a flight plan is just a record of intended route and timing for ATC coordination; and an ARC relates to airworthiness or registration, not the legal permission to use radio equipment.
