Yes it has been done to death but I am the first to mention it is(HASELL) actually contained in two of the UK best selling flying traing manuals so what does that tell you? It tells me that instructors never bother reading the very books they telll their students to go and read!
Bugle learned to fly at Cranfield in the 60s when Birch & Bramson was the ONLY text book in the UK so I do not understand why he poses the question -who started this nonsense?
The CAA examiner I mentioned in the seminar reacted in the same way with the same question. It proves to me that this is an indsustry where the right hand doesnt know what the left hand is doing and people have forgotten the main objective of producing the safest possible pilot. Ego before student isnt best practice even on forums
