Guys thank you very much for the advice and comments. Some of it positive and some not so.
I know that I can fly a plane physically, but perhaps my mental ability to make rapid mathematical calculations while under pressure would not be so hot.
I think on reflection, I will be better off getting my PPL and IR and stick to being a pleasure pilot (safer for the travelling public too). I know that pleasure is something that I am very good at, and highly qualified in!
I wish you all the best of luck and success as qualifying and qualified commercial pilots.
Dead stick..........
