In Germany, ADFs are required for IFR training aircraft. This is
different from the UK, as Peter posted.

DMEs are required for IFR flying. No substitution by GPS. Yes, I
know...

Related question then...

Some German airports (with class F) appear only to have GPS approaches,
which, according to the plates, require some sort of qualification. Is
there a practical way for a foreign pilot not based in Germany to get that
qualification?
