Hi Alex,

once more thank for the help, I have managed to complete two flights, one using TO and one D-TO with 31 assumed temp and in both the cases it went well and according to what TOPCAT has foreseen (not easy to say that the remaining runway was exactly the one predicted but I was definitely not on the other threshold) so for these two cases no issues at all, I can also say the rest of the flight was smooth and without any issue (I use it coupled with MCE) so pretty happy with it!
For the D-TO 1 or 2 try to use the saved file I have attached to my previous conversation, if you will experience my same issue you will you will not be able to lift off before the opposite threshold, also when accelerating the feel is something is missing, just to see if is something on my system or not in the end...

Thanks again!
