Aircraft radio was introduced for communication in aviation. This was divided into different classes, including BZF I and BZF II.

What BZF is

The restricted radiotelephony certificate is a radiotelephony certificate for the flight service. There are different classes of this certificate with different authorizations. The first class (BZF I) entitles the holder to use radiotelephony in German and English in accordance with visual flight rules.

There is also the BZF II, which allows radiotelephony within Germany in German according to the visual flight rules.

You can find detailed descriptions of other classes of aircraft radio certificates on the website of the Federal Network Agency.

Why this is relevant for drones

As the BZF I and BFZ II are valid for visual flight, unmanned flying objects, i.e. UAV and UAS, are also included. For users of the VLOS, EVLOS and BVLOS operating modes, the aeronautical radio certificate is not uninteresting, as communication with the USSP will be mandatory from January 2023 as part of the new regulation.

The flight radio certificate is therefore also important for the USSP, as it must communicate with the pilots to ensure the safety of the drones.

Due to the new regulation, it is also advisable to have a radio operator's certificate in addition to a drone driver's license or remote pilot's license when flying drones.

The UAS team at b.r.m. IT & Aerospace has many qualifications and awards. The IT and UAS consultant Markus Rossol is in possession of the BZF I certificate. The license for the restricted radiotelephony certificate I for the aeronautical radio service is issued by the Federal Network Agency for Electricity, Gas, Telecommunications, Post and Railway.
