410, sorry I was thinking you were talking about a hold to the north.
I am not sure if the aircraft holding would be able to limit their flightpath between DUB and SHJ, they are pretty close. It will take a few people around a table with PANSOPS etc to work on this one. You also have to take into account military airspace and Rulers palaces that are not allowed to be overflown!
With regards Heathrow having the jumbled target problem sorted; if I remember correctly from a couple of visits to LATCC, the APP controllers vector them out the hold and the ACC guys used to drop the next couple down and hand them off. That right Nimmer?? Here we have the additional problem of our system not differentiating between the aircraft under my control and those of another sector. I see every single thing flying from commercial traffic even overflying, military, vfr trainers, choppers and the occasional boat out of Jebel Ali or Port Rashid too. Plenty of targets, all the same colour....
The second frequency for Dubai ground is operating now giving clearances, staff permitting.
