Hi Alex,

first of all thanks for your tests, for what concern the performance sw I use Topcat, I make my flightplan with PFPX and then I send it to topcat so I rely on it for takeoff settings (flaps, thrust and so on).
Let's say that for the flights I was testing there were the conditions for a D-TO 1 but then remaining rwy was not the one reported by Topcat, I lifted off on the opposite threshold instead, this never happened with the other aircrafts I am using so this is what took me here after reading someone else was having presumably the same issue.
