So inferring from englishal's conclusions, the pilots most likely to have an accident are;
Qualified vanilla PPLs, flying VFR - and they're probably not going to die during a forced landing.
And you're much safer off under IFR - so quite possibly IMC, and also safer flying SEP & having done aeros.
So ideally we would keep the IMC and make it a worldwide qualification, and also bring back aeros & spinning to the PPL syallbus.
Or have I got it totally backwards?
