ILS 119.5 - I speak fluent German, so that wouldn't be an issue.
From what I have learnt so far, the training is conducted in English and it seems as though their only requirement for a certain competency in German lies in the fact that certain (smaller) operational areas within Germany do use German as R/T.
I'm guessing this would only involve VFR operations in quiet locations. Please correct me if I'm mistaken!
I was just curious as to whether anyone here has been down the German route; it's interesting to get opinions from a variety of sources.
Thanks,
ILS RWY27L
