When I did twin convex I was comfortable and (possibly even) proficient after 3hrs, but the law requires min 6 hrs, so we played for the other 3 (night, IF and instrument work) to keep CAA happy. Conversely when I did the Albat conversion after having twin time I did 7 hrs dual before I was comfortable and before the instructor would "let me loose". Law requires just 1hr. bottom line is you are in charge of your destiny. Take responcibility for your actions. I always ask instructor if he would let his wife or family fly with me. If he even blinks we go on. unfortunately some milk the system. I have been billed for 2hrs I did not fly as instructor said CAA would not accept a log book with less than 1 hr for complex convex. Must be min 3 hrs. I was naive and left it, but I should have taken him on. I blame CAA for the situation. They are creating an evironemnt where it more about minimuns and covering your arse as school/instructor than safety. Catch 22, but my opinion is that they have dropped the ball here a long time ago.
Back to LSA
LSA has reduced medical requirements which is possibly why it is so popular in USA. Limits on performance (can only almost kill you mentality) and only 1 pax (reduced liability). IMHO THE BIG ISSUE with PPL is that you can drive ANYTHING with a PPL and convex. ANYTHING - If you can afford it you can drive a 747, 737, BBJ, King Air, Lear Jet with a PPL after initial PPL and convex - not sure you get insurance, but if you can afford a 747 you possibly don't need it. Obviously it an extreme situation, but legally once you have a conversion onto that aerie you can fly it with many unsuspecting pax on board. When was last time you asked PPL how many hrs he had on type or total hrs before going for a flip. Some take it as insult and usually they are the dangerous ones.
I thus think there is a place for the "smaller" aerie license (LSA or 3axis - but both my be overkill), for the fun round the patch flyer. I fly high performance pistons and agree that for that purpose LSA is not acceptable in isolation, but there is some merrit in building LSA hrs and then converting to PPL. Again instructor needs to judge when you are compitent and maybe they need to go back to designated instructors. if you want to "take a shortcut" you need to do it with CAA designated examiner. Else you have to comply with the minimums? I don't think CAA has the capacity or ability to do this, but ti would be nice.
I also think if you have PPL you should be allowed to fly LSA/3axis with a simple convex. If I understand the recreational pilot's license this will not be possible and I will need RPL, PPL, MPL & MGPL and remain current on all of them?
I see no point in having 3 axis microlight and LSA. Confusion rules KO!
