Its becoming clear. I can use my group A permit a/c to do the NPPL SEP course and flying test. Must be at a licensed airfield.
So a minimum (will depend how good you are) of 3 hrs flying, a nav test, flying test and one general exam, as long as you have 32 hrs in 3 axis microlights. Nice
Lots of "A" schools have no real feel for whats needed, they want to sell you loads of hrs on a hired a/c, plus exams. Suppose its not in their interest to take an experienced 3 axis PPL (M) and make it easy to attain a NPPL SEP. I am cool with that.
