True but you need a pretty high level of flying skill. I have never met a 300 hr PPL that could fly at a high enough standard to realistically commence the FI course. Even the CPL's almost always need some additional dual to polish their stick and rudder skills before I can start teaching them how to teach.
Even if I had never used my FI course, I still would have considered it money well spent as it moved me to a whole new level of flying knowledge and skill. It made me a better pilot in every way.
Agree 110%.
It looks quite likely that either a BTO or RTO option will be introduced as an alternative to full ATO status for RFs. This is good news for GA and therefore part-time instructors. It's sad that EASA are having to spend so much money unpicking something which should never have been in the first place.
