Additionally, for flights to/from France, the French Authorities require the frontier crossing point (the UK/France FIR boundary position) to be included in Item 15 (Route) of the FPL.
Hmm. I can't find any support for this in
France AIP ENR 1.10 nor does CAP 694 cite any regulatory document. Has anyone had a FPL rejected by French AIS for failure to comply?
