Apologies, don't want to continue off topic, but the"Stow the boards" etc. was this instructor's suggested sequence to ensure that there would never be a repeat of past errors - viz. attempted go-around with the speed brakes deployed and/or auto throttles retarding (Uncommanded by crew) It happened, and with Murphy ever present, book or no book, I know which sequence I would prefer!
And isn't this a typical example of an instructor convincing his students that his theories are best and by inference to disregard the manufacturer's recommendations. Has this instructor conducted measured and verifiable tests of his theory? No wonder one hears the oft repeated complaint by students that lack of standardisation between instructors is most annoying.
