Hi Norbert

Egon Führung: The Freya-EGON was a secondary radar, which interrogated the transponder in the aircraft. EGON Führung was a method to give navigational assistence to day-fighters, night-fighters and offensive aircraft based on positions obtained from the EGON. For a description of the fighter application please see:

Y Führung: As above, but utilizing a system, which, based on exchange of radio signals between the ground and the aircraft/formation, established the position of the aircraft/formation. It constisted of the Heinrich Peiler and the Hans E-Mess Gerät. Y-Linien refers to the frequency combination used for interrogation and responce.

ZZ Landung: A method to perform an instrument approach at night or in bad weather. It utilized non-directional radio beacons, the radio-compass in the aircraft and an "observer" in the ZZ-Hütte. His job was simply to establish when the aircraft was overhead on it's final approach, inform the pilot who would then bring the engines to idle and land straight ahead. Please see attachment for the set-up at Fligerhorst Grove in central Denmark.


Tornadoflug (Me 262 logbook): A number of Tornado Peilers were deployed throughout the area of operation. When the pilot transmitted, the position of the aircraft would be established by taking bearings from 2 or more Peilers
