This is all nice for T/O, but DA also effects our landing distances, and no one has ever been able to tell me why we don't have to correct for DA changes in computing landing distances...

Think about it, if 2 kts fast over the fence adds about 5% to landing roll, and you are at a 6000' MSL strip in August with temps in the high 90's, then you TAS is going to be up there as you cross the fence.

I know most field lengths are more than sufficient to account for any increases in landing roll due to DA, but what about an abnormal situation, we have no way of calculating the new roll out. Unless DX has it buried somewhere, but I doubt it.
