Hello Regis,
great work (again), but I have three comments:
1. Please delete the CTR Sarrebruck from your file. The complete CTR including the part on french territory is in the german airspace file
2. Same for the Zweibrucken CTR and Karlsruhe CTR
3. Please declare a CTR as a CTR and not as class C or D. Instead of " AC D " use " AC CTR "
It is in fact no difference if a CTR is defined as class C or D. But class C or D (not CTR) for example in germany is a totally different kind of airspace.
If someone wants to penetrate a CTR, he has to contact the appropriate Tower. But, responsible unit for class C or D (not CTR) airspace is the radar controller.
Happy New Year
