Hi
For Morocco you need to file the ATC plan 24 hours prior to planned operation - although we have done it in two or three hours due last minute charter booked with no issues. If there are any issues with your route / schedule you will get a message from the DGCA via AFTN.
We haven't yet. And that was based on private as well as commercial non scheduled.
CAP555 gives you all the references or 2010 Acu-Qwik gives you good references too.
Cheers
Vince
