just out of curiosity, what kind of rejection (not accepted FPL) message did you get from IFPS system?
RS: Traffic via SARRI Z818 SARRI LADAT Z818 LADAT is on forbidden route ref: EUROED58A ED AIP (ENR 3.3.Z*) Z818 MANEM SARRI and - then I canīt read any more as my flightplanning/verification system does not have the space to show the complete message. That message still comes up.
The real issue for me is, Eurocontrol throws all these regulations at us and does not give us either the required answer nor tools to deal with the "!!!!" THEY created. The route catalogue for example is nice an dandy, but almost exclusively for routes between big airports. And because we fly to and from small airports and not generate enough revenue for EC, they just treat us.... badly.
