This is nonsense. No-one is trying to promote any commercial interest, but trying to find what (sounds to be) a good technical reference. If it was good enough for SAS and Honeywell, that'll be good enough for me to take a look.
Clearly from reading the thread, finding the book is not proving so easy. Because the author is Swedish and the Swedish websites are mostly Swedish, the normal English language search systems don't help. I googled Olle Åkerlunds and got nothing intelligible to me. Although return #2 from Google might provide some light relief
Åkerlunds
Through PMs I eventually got to the current publisher:
Håkan Örtlund Produktion which does have a Flag that can be clicked to give some English words. The history of the book is that "From takeoff to landing' has been around for some twenty years aiming at operational people and instrument procedure design.
Three years ago, a companion book – From power ON to power OFF – was introduced, dealing with aircraft performance. These two publications have now been updated and combined into a single volume - INSTRUMENT FLIGHT PROCEDURES and AIRCRAFT PERFORMANCE.
Part of the remit of Tech Log is to spread technical knowledge. This is the first book I have heard of on instrument procedure design, and there are only a limited number of books on aircraft performance, so this link is potentially as useful as any of the others to D P Davies, Swanson and the like.
I have no commercial interest or knowledge of the author or publishers.
