heres an exaple of my displaced threshold now to paint the picture above and the taxiway A at the end of the post


taxiway A joins the runway at 90 degrees to the tarmac but theres a displaced threshold of 245 feet before the runway starts


now in the file i have taxiway A finish in the centre (width wise) of the runway at the joining point to runway 15 and runway 15 start at the same point


now i can taxi my planes on to the runway and use the cto and away they go but using the pos command they just sit saying already there. Should they not taxi forward by the displaced ammount on the runway so there sat ready at the displaced threshold? or have i got the wrong end of the stick here with the file?


as always looking forward to your advice

I'm not entirely sure I understand your question, but I can tell you that displaced thresholds have nothing to do with takeoffs or positioning. Aircraft are allowed to use the displaced threshold area for the takeoff roll. Displaced thresholds only affect the point at which aircraft touch down when landing.
