Flying under IMC

Hi,

i'm based in Germany with a FAA-PPL ASEL.
It's very interesting to read the differences in IFR-Flying in the
States and in Germany. Although the two countries are "ICAO-countries"
they are not
participating in same air work to each other.
Well, i think ...when learning for an IFR-Rating you should know
before what you are allowed to do with it or not after passing it.
I think most "VFR"-Pilots only know about the new ability to fly in
clouds without reference of the ground surface.
It's very interesting for me to know how the real IFR-flight is
working, what problems with ATC you have when flying under IFR, the
change IFR-VFR, and a lot of other things....and that....before
"doing" the Rating.

Thank you all for asking my questions....

Peter
