Your analysis is very technincal and a bit ott I think for what is required. I would have answered as per gleim on all quetions and even though the wording may not be correct, unlike JAR there is only one answer that could be correct, in my view. If I had gone with 'no correct answer' on all the JAR papers Ive seen I would be still struging with PPL. The fact is ,Pilots dont understand this theory to this level and are only trained(especially in FAA) to understand the practical principles of flight, not theory, as it is just too broad a subject to cover in detail. My view!
