Yes - I am aware of that, but
The stall margin is reduced by less than 10%. Second immediate move : lower the nose, keep the speed.
- herein lies the dilemma. You don't give any clue as to what you are 'quailfied on' (or indeed 'if'), but would you suggest doing that at 200AGL/400/600 etc? It is not that simple! Lower the nose and increase speed by up to 10% you say. I wonder where they would have 'landed' doing it that way? What they did worked out. It would be nice to have a little more than that from a qualified source. Indeed on 10 and 9 April you called for the same. Do you now have the answer? M Mouse suggests that BA 'trials' prove there would have been a better way (9 April).
reducing from landing flaps to approach flaps is a normal move in case of thrust problems.
- is a new one to me. Can you substantiate that SOP for any carrier, and perhaps amplify 'thrust problems'? Also I am uncertain what "a N-1 go-around" is and I am also used to a 2.5% 'approach' gradient.
