I just bought a copy of "Ace" edition 2 - still on the first chapter and it is already driving me nuts! It consistemtly refers to the "camber" of an aerofoil as the "chamber" and makes some very dubious statements about the differences between high and low aspect ratio wings.
There are lots of other places where it has me scratching my head thinking "is that right?". As a result the book is near useless other than as a prompt to go and look things up elsewhere - you certainly can't trust the answers it gives unless you already know that they are correct.
