Call signs for aeronautical stations; application for an Aircraft Station Licence

If you wish to participate in aeronautical and aeronautical navigation radio, the BNetzA will assign you the callsign with the Aircraft Station Licence on application. In addition, you must notify changes, for example, the holder address or the radio technical equipment.


For communication and navigation, aircraft and balloons use the frequencies of aeronautical and air navigation radio. The Federal Network Agency manages the corresponding frequency ranges. If you want to participate in aeronautical and air navigation radio, you need a call sign for the aeronautical station of your aircraft.

The callsign will be issued to you upon application in the form of an Aircraft Station License by the Federal Network Agency.

You must submit an application when you become the owner of an aircraft with an aeronautical station. An aircraft is, for example, an airplane or a balloon.

If you already have an Aircraft Station License and the following changes occur, you must submit a change application:

  • Changes to the aircraft's radio equipment
  • Changes to your name
  • Changes to your mailing address
  • Changes to your domestic receiving agent


  • You become the owner of an aircraft.
  • You are the owner of an aircraft and your name, address for service has changed or you have made changes to the radio equipment.
  • The domestic receiving agent or agents has changed.
