Some of the Approach controllers at DXB regularly use the 3 dimensional / vertical avoidance of Wake from the preceding Super, which is very good.
There is of course another option, as used by other busy airports. To use both sides of downwind.
Some time ago, when DXB arrivals were being significantly effected by some nasty CBs, lots of RT asking for wx avoiding tracks etc, it was very busy.
Yet on the opposite side there was no weather. We asked for a Left Hand Downwind for 30L, ATC said why? No wx says us. ATC grabbed it with both hands and switched the flow. RT dropped by 50%.
If the Supers flew the opposite downwind orientation from the rest would it ease the problem a bit?
Obviously there would need to be SID considerations but worth a look?
