Sorry but that video is totally unrealistic to how the situation would develop in real life, that crew clearly is rehearsed and knows exactly what is coming. Having conducted several investigations into engine failures and RTO’s you can’t underestimate just how much of a factor the ‘startle effect’ is. The best instructor I ever had in the sim once told me that you should be deliberately slow in the Sim as when it happens in real life you will go twice as fast with the adrenaline, from all the crew I have interviewed that does seem to be the case. I have seen some amazing lapses, mistakes made in the heat of the moment when under pressure from an unexpected situation, best thing you can do is ‘review’ over and over which is what the BA crew did, things were done wrong but thankfully it was mopped up by each other to a good outcome.
