Just for clarification, the fellow I refer to was an American airline pilot. I ran into him last year while bumming a jump seat and having no personal need for it, I promptly forgot the critical details. The conversation was specific though and I recall him showing me pictures as well as the licenses and logbook entries. I believe that it has to do with the wording of the FAA regs which define a gyrocopter as a rotorcraft or something like that.
It will probably take some careful reading of the CAA regs to determine if the same is possible there. I doubt you'll get much help from the blokes at the CAA - do your own research. Are there any lawyers on the forum who might want to take this on?
