Multiple Choice

When must the radio license be displayed in an aircraft equipped with two-way radio?

The requirement centers on regulatory compliance for international flights. The radio license is the certificate that authorizes the aircraft’s two-way radio, issued by the FCC. When the aircraft is traveling internationally, foreign aviation authorities may request proof that the radio equipment is licensed, so the license should be displayed in the cockpit to satisfy those checks and speeds inspections. For domestic operations, there isn’t a requirement to display the license to authorities; it must be on board and valid, but visibility isn’t mandated. Displaying it all the time, only during maintenance, or only when parked doesn’t align with the international-regulatory purpose of this requirement.
