however I am not convinced for the "average" pilot you are ready to start aeros at the end of your PPL or even during your PPL. Why? Well the PPL for most is fairly challenging and you are unlikely to end it being fully comfortable and confident with the aircraft throughout its flight envelope.
I doubt that many people significantly expand their knowledge of the aeroplane's flight envelope once they have a PPL. I certainly didn't - and that was one of the main reasons that I wanted to try aeros
