Currently doing a flight from Christchurch to Sydney and at cruise altitude, went over to the PRG page to check things out and look what i see,T/D is LATER than my ETA in YSSY!!Please explain!http://forums.avsim.net/user_files/37496.jpg

Hi Clayton, This is a known issue. There have been several posts about this issue a while back. It seems there are different opinions regarding the required accuracy of the T/D estimation. I, as you I assume, don't find it realistic that the estimation of T/D can vary as much as aprox. 30 minutes as I have seen it do in certain cases. I think it all boils down to an issue with the estimation of the distance to the T/D point. I agree with you, logical sense would indicate that the T/D sould never be later than the arrival at the destination airport... Why that one was never caught, I don't know. I think the thread ended with a plea for a real world NG driver to pitch in and explain what should be expected regarding the T/D estimation. Hopefully this issue will be adressed in SU2.With kind regardsBoaz

thanksi have also noticed, on this flight, that my flight is taken some what longer, for example i have the flightsim on a separate computer and the i have both computers with the same time, but when i fly the 737 my FS computer gets slower and slower, how can this be,i am about to land in SYD but i am already 15mins behind schedule, i can't understand why.
