Right now it is said the capacity is 31 per hour, and that's squeezing it, given the radar capabilities (hardware and software).
Perhaps some of the "tower flowers" or approach folks can elaborate better.
Frankly, seeing as the current trend is an increasing number of both A380s and a320/737s, BOTH of which increase the spacing requirements on final from Dubai's historical preponderance of heavy following heavy, I would be very surprised if runway capacity doesn't DECREASE.
Rumours are also now circulating about a coming long term (I think it was 9 MONTHS) runway closure for resurfacing, which will mean single runway ops, with the attendant decrease in capacity, for quite a while.
Doesn't help a bunch on the Tardi where 10 miles in trail is the rule.
In fact the standard spacing through TARDI (and RIKET) according to the letter of agreement between Dubai and UAE ACC is 5 miles, constant or increasing. THE LOA says the same for RANBI and DARAX but this is increased to 10 miles by the ACC as a non-standard requirement and renewed at each watch handover. Worse is the new flow imposed by Muscat recently during peak hours, which is 20 miles between subsequent RIKET departures and 7 MINUTES between TARDIs!
