Having completed five hours of aeros training back in 19mumble-mumble as part of a CAP509 course, sadly in a C152 Aerobat instead of a proper aeroplane, and subsequently taken a break from that kind of thing for a few years, I have been flying a Yak52 in various unusual attitudes regularly for the past five years.
I presume my rating will be granted no questions asked as a result.
Out of interest, does anyone know if a Yak52 is an "EASA" type or not? I assume it is as it has a CAA Permit (as opposed to LAA).
