Backpacker,
It ain't in the ANO.
LASORS is only advice. I repeat, my three-axis instructor has no microlight rating/licence - only a JAR SEP.
He also, of course, has a microlight instructor's rating.
It took the CAA a bit of convincing to put the microlight instructor rating on a JAR SEP - which was in another thread on Pprune - but it IS the law.
Of course, I stand to be corrected if the ANO was ammended in this respect last month,
With kind regards,
XA
