BZF Hero

Read full description

Getting ready for the BZF? The BZF is the German aviation radio license (BZF I for English, BZF II for German radio telephony). With BZF Hero you practice radio calls the way they really sound: you fly a real route between German airfields and talk to Ground, Tower, FIS and Approach โ€“ by voice, with a push-to-talk button just like in the cockpit. HOW IT WORKS โ€ข Choose departure and destination โ€“ more than 1,000 airfields in Germany with real runways, taxiways, frequencies and reporting points. โ€ข Hold the transmit button and speak your call. The controller answers by voice โ€“ clearances, traffic information, taxi instructions. โ€ข BZF Hero checks every call: callsign, order, mandatory items, readbacks, standard phraseology. LEARN OR TEST YOURSELF โ€ข Learning mode: guided step by step โ€“ with a sample call, an explanation of why it is done that way, and tips after every call. โ€ข Exam mode: no help, with a debrief at the end โ€“ just like the practical exam. โ€ข English or German: practice aviation radio in English (BZF I) or German (BZF II). REALISTIC FROM HOLDING POINT TO PARKING POSITION โ€ข Initial call, taxi, takeoff clearance, leaving the control zone, FIS with transponder and traffic information, approach, traffic circuit, landing and vacating the runway. โ€ข Map in the style of the ICAO chart with airspace, reporting points and traffic circuits; your aircraft flies the route in real time โ€“ or in time-lapse. โ€ข Watch mode: let the pilot do the talking and listen to how a whole flight sounds. WHO IT IS FOR For student pilots preparing for the BZF exam, for pilots who want to brush up their routine, and for anyone who wants to understand aviation radio. TRY IT FOR FREE Your first flight is free. For unlimited flights there is a subscription (weekly, monthly or quarterly). Payment is charged to your Apple ID; the subscription renews automatically unless you cancel it in your Apple ID settings at least 24 hours before the end of the current period. Note: BZF Hero is a practice tool and no substitute for training at a flight school. The maps are not intended for navigation.
