I guess the original quote by vish (assuming that DP was confused on definitions) is D P's way to lead up to the need to limit 'incidence' (AoA) by means of stick pushers? On its own it made no sense, since 'incidence' (AoA) is a 'valuable parameter' in any stall, is it not?
I don't think its fair to say DP was confused by definitions. Throughout the book he uses the word 'incidence' to describe what most of us understand as the AoA. If one would read the 'language comparison' page (1 page before intro) and the 'glossary of terms' (pg 4) before reading the meat of the book, things would be much clearer. The 3rd edition was written in 1971, and with him being (or was) a certification pilot for the UK CAA (if i understood that right), i guess it is fair to say he used the proper terms that were known 'back in the days'.
But to be honest, i would of liked a '4th' edition myself that would make use of 'modern' terms when i read this book.
