mm_flynn - to this day I have no idea how one could file
and fly out of LFAT to somewhere north in the UK at FL250, without initially ending up OCAS and having to hunt around for an IFR clearance.
If one did this in the UK, the tower would get you a provisional airways join, or (if doing a farm strip departure) one would get it from London Info.
But on an LFAT departure to the north, one is leaving the area where Paris Control could give you a clearance (and leaving it at say 150kt
) and since London Control cannot be (
AFAIK) contacted directly by any method, that leaves only London Info, and being held down OCAS until this is sorted.
It may be better to depart LFAT and initially climb along the coast, until Paris Control have you sorted?
A tricky one...
