To answer the original Q: Firstly - why were you recommended to read this book? The CX interview perhaps, or just out of general interest?
Davies' book is a good read, but I found it to be like an old ATPL book. It says a little about a lot - most of it old news now, and covered by FCTMs and loads of other good books out there. Skimmed through it for the CX interview, but learned very little new from it. I also bought "FLYING the big jets" by mistake, which was a eeeehrm....rather dull and uninteresting book best suited for laymen I guess.
I recommend J.P Ternvigs book "Aerodynamics for airline pilots" (Sold through SAS/Oxford Aviation Academy I believe). Captain Ternvig specialises in air combat and medium/heavy jet aerodynamics. This is the ultimate read on the subject, and much more in-depth and interesting
