Yes, I can mate. (A2 and bar!) I can't right now as I will have to draw a diagram (4 colours naturally!) and I don't have the technical ability to include it in this post. Besides, Im off to San Fran in a few minutes. I you e-mail me your snail mail address, I will pop it in the post when I get back on Sunday.
A good book on the subject, and seemingly written for befuudled A2 candidates is 'Aircraft Flight' by Barnard and Philpot ISBN-582-00338-5
Cheers, Dan.
PS Can the Tutor get to San Fran? (VMC of course)
