A third party may be allowed to use FAA radio communications when the information pertains to ___.

• A. ATC clearances
• B. the safety of aircraft operations
• C. field conditions
• D. taxiing aircraft in nonmovement areas

Answer: (B)

The thing being tested is when someone outside the flight crew is allowed to use FAA radio communications. A third party may use the radio only when the information relates to the safety of aircraft operations. That means if an observer notices a hazard or condition that could affect flight safety—such as a runway obstruction, debris, or hazardous weather—they may pass that information to the control facility so pilots can take appropriate action. This emphasis on safety of flight keeps the frequency clear for essential, risk-reducing communications.

ATC clearances and routine taxi instructions are responsibilities of authorized personnel, so those transmissions aren’t something a third party should issue. Field conditions are part of safety of operations, but the general rule is safety of aircraft operations covers information that could impact safe flight, including such conditions.
