Correct, it only currently applies to microlights.
Where would they come from? Probably people like me who are coming up to retirement in a few years and want to put something back into aviation to help the new blood coming in. I don't want to be a career instructor, neither do I want to build hours. I am looking for a way to keep flying while I can still pass the medical and if I can help some others along the way, all the better.
That is why I am doing a microlight AFI course in a couple of weeks, and if the rules ever do change so I can become a rotary AFI without all the CPL hassle I will do that as well.
