Airbus EFB T.O Performance
Hi guys, is anyone here familiar with the concept the Airbus fly smart EFB uses in calculating takeoff performance? In particular I'd like to ask about the stop margin figures. When we are runway length limited, we often get stop margins in the region of a couple of meters, the lowest I've seen is 2m.
It does bring some uneasiness when we see that simply because it's too close for general comfort. Does the calculation take into account stopways (if there is for that runway), or does it always assume a balanced field? Do you guys try to increase the stop margin when presented with figures like this or do you take it as it is?
