Guy and Tower thanks for that. The 380 seems to hit Vapp around at around 1000' if flap full is taken at 1500' and speed is reduced from 160kts at 5nm. Pretty much the same as the 330/340. I guess as tower says it all depends on what speed is actually flown and when it is actually reduced.
Was given descend to 10000' at 2000fpm and 230kts at 120 miles the other night. Only cost 1500kgs of extra fuel to what the predicted for the approach. It would be nice if DXB was given a bit more upper airspace if it would help with the extremely early descents.
