Radio operator certificate
GeneralA radio operator certificate is an official document that shows you are allowed to operate an aircraft radio. It is required when transmitting on the aeronautical radio service, and the privileges may be limited by the type of certificate, the language used, and national rules. You should make sure your certificate is valid and suitable for the flight you are conducting. If radio rules are broken, the certificate can be suspended or revoked.
