from my limited experience on flight sim 2002 i found that due the acceleration of larger aircraft a rejected takeoff shouldnt even be considered say 10kts before v1. ?
Nope. V1 is the magic number (slow enough to stop and fast enough to go) number. V1 is calculated based on all weight, weather and distance factors. Taking into account all those factors V1 is the thin red line after which any attempt to stop will result in an overrun. The wording in the ATPL exam is "
must stop before V1" and "
Should continue after V1". FWIW not only is FS2002 (as good as it is) never going to model/replicate the complexities of the interelated conditions but also you don't have enough data to calculate the correct V1...hence a pretty invalid comparison.
ASDR = Accelerator Stop Distance Required. Basically the shortest distance that your a/c requires on the this day on that runway to accelerate to V1 and then stop. If this is greater than the ADSA (distance available) then you need to loose some weight...somehow.
