Thanks for the replies. Am I not right in thinking that our microlight system in the UK is regulated in that you get a PPL(M) on qualification ? I'm just wondering if I could argue my case with Gatwick on this basis.
I admit I should know more about this area, but my microlight instructing has all been as a part-time instructor, so I show up, obey all the local rules, the ANO and the CFI amongst other things, without delving into the minutiae too deeply. I do also have 140 hours of SEP instructing, many of which were in far more beaten up, less capable C-152s !
I am approaching the 500 hrs multi-crew time required but I would really like to avoid having to duplicate the 240 microlight instruction hours if I can help it, mainly because my day to day flying is in corporate so the hours are built up quite slowly (compared to say, airline flying)
