I don't think anyone was suggesting teaching anything other than the way Mr. Boeing says it should be taught.
John Farley just pointed out that you had made an error, an error that is probably not significant in line flying, as any error will be on the "safe" side.
Comments such as
I will post a copy of your note on the pilot's bulletin board, among other jokes...
Incidentally, I recommend you also read "Handling the big jets" by the late D.P. Davies, ARB Editions, London.
are ill thought out
John Farley is incidentally a very well respected pilot, suggest you do a search on Google for "John Farley harrier" and have a look at the results
