OK, 737, I guess you must be right - I don't understand enough about the subject. I always thought that Annex 14 set out the SARPs in order for an aerodrome to gain certification and to offer itself to aircraft operators. The operation of aircraft seemed to my simple mind to be governed by other regulations and, as you claim to be in Europe, I took a guess that you would be operating under JAR-OPS Part 1 (or whatever the current applicable legal text is). Of course, if you can demonstrate that this is not the case, and can operate the flight under a different code, you might have a range of other options available. I guess I can only aspire to understand such complex things.
