Forgive me if I am missing something blindingly obvious here!
Most of the previous threads refer to the possibility of entering erroneous figures into THE laptop, and transposing figures from THE laptop to the MCDU.
When I did my 'FOVE' course at Airbus we were taught that both pilots did the performance calculation independently and the results were compared between the TWO laptops. That precluded the possibilty of two incorrect calculations. This is standard SOP in my company.
It could well of course be that on the day, with many distractions that abound on a flight deck just prior to departure when everything comes together in the last few minutes, that caused the error to go un-noticed.
I presume EK use the same laptop system, so is it not SOP's for both pilots to do the performance calculations? If so, then presumably the problem started earlier in the chain.
Without, of course, any knowledge of what happened, the old adage with computers - 'rubbish in = rubbish out' springs to mind!
