AeroRadio Pro
The ultimate free training portal for aviation radiotelephony
Welcome! If you hold a foreign license or prefer English communications, here is how the German radiotelephony system works and how to use this trainer:
• The "German Language Requirement" Riddle:Germany has hundreds of uncontrolled VFR airfields where radio communication is strictly mandatory in German. A pure English certificate (BZF-E) legalizes international flights but bans you from landing at these local fields. To solve this, you have two options depending on your current background:
• Option A: BZF II (German VFR Only)
Are you an international instrument pilot who already holds a valid AZF or ICAO English IFR rating? Then you do NOT need the BZF I. To legally land at local German airfields, you just need to pass a quick delta-exam for the BZF II (pure German VFR), as your English privileges are already covered by your IFR rating.
• Option B: BZF I (The Mixed Full-Certificate)
If you start from scratch and want full privileges for both German airfields and international cross-country flights worldwide (including Europe), the BZF I is your choice. (Keep in mind: BZF is strictly for VFR/Visual Flight Rules only. For IFR, you absolutely need the AZF!) The exam forces you to perform local departures in German, while the return/inbound flight is conducted in English. Keep the briefing board in German; it matches the official ATC grading parameters.
• AZF (Pure International IFR):
Simulates professional Instrument Flight Rules. Conducted 100% in English from startup to touchdown according to worldwide ICAO standards.
