AFZ / AZF
AFZ and AZF both refer to the highest-level German radio communication certificate required for certain types of flying within German airspace. These acronyms are used interchangeably:
- AFZ – Allgemeines Funksprechzeugnis
- AZF – Allgemeines Flugfunkzeugnis
The abbreviation may differ depending on the document source (e.g. EASA vs. LBA), but they denote the same qualification.
Purpose
The AFZ/AZF is mandatory for pilots who:
- Operate flights under Instrument Flight Rules (IFR), or
- Fly in controlled airspace with English-language ATC, or
- Intend to use English phraseology in international or German airspace.
Content & Exam
The AZF/AFZ exam covers:
- Advanced radiotelephony procedures
- Phraseology for IFR operations
- Emergency communication
- Route clearances, departure and arrival instructions
- Holding patterns and approach procedures
- Use of English phraseology in controlled airspace
The exam includes:
- A theory section (multiple choice and written questions)
- A practical exam with simulated ATC interactions, often in both English and German
Comparison to Other Certificates
| Certificate | Scope | Language | Use |
|---|---|---|---|
| BFZ/BZF | National certificate for VFR flights in uncontrolled airspace | German | Basic private flying |
| EFZ/EZF | Extended VFR certificate for controlled airspace | German | VFR in controlled airspace |
| AFZ/AZF | Full radiotelephony certificate | German + English | VFR and IFR in all airspace |
Validity
The AFZ/AZF certificate does not expire. However, language proficiency, especially in English, must be revalidated according to ICAO language level requirements (usually every 4 to 6 years, depending on the level achieved).
In Practice
Holding an AFZ means a pilot is fully certified for all radiotelephony communication required in German and international airspace, including complex IFR scenarios and multilingual operations.
