Thanks for the replies!
I assume that the direction you takeoff in from DXB and the SID also play a role in choosing the accel height.
If you need to make a 180 after takeoff, then accelerating in the opposite direction would make little sense. so 1000'/3000'.
I have noticed the majority of the SID's have a 220kt restriction at certain waypoints. Most likely to keep the turn radius to a minimum. Is this usually waived or do you have to stay in flaps 1 on a heavy takeoff in the 777 until past those respective waypoints?
