Has anyone every noted how inaccurate these figures are using either the simulator or real life? The amount of factors being factored in have, IMHO, made the figures ridiculously conservative.
This is compounded by the fact that in the sim in practically every non normal scenario reverse is reduced to idle by 70 knots and manual braking inevitably comes in and the aircraft is allowed to roll on a bit once the aircrew realise they have in fact, 1,000s of metres of runway left to stop in.
Forget the fact that 90% of Airbus pilots aren't aware of the logic of Autobrake Medium and how it affects us on a practical basis.
We seemed to have moved from accuracy to avoidance of liability.
