Hi SS41.
Aerodrome controller may depart 3 aircraft bound for tonvo/laldo and 3 aircraft for tardi every 10 minutes.
OMSJ, OMRK, OMDM and OMDB are to be considered as one airport for the purposes of flow control.
The reason is staff shortage in Muscat.
Taxi flow = keeping aircraft on stand so as not to choke the holding point with traffic that can't depart. Also remember the published taxi time of 15 mins. Not brilliant on an airfield the size of Dxb and it's kind of pointless publishing this anyway as records are not published as to delays incurred measured against this. Anyways, in theory you should be airborne 15 mins after push (or requested push to be more accurate) so that is our aim regarding taxi.
Departure Radar seem to be given different goal posts to aim for regarding distance between aircraft through the gates (normally varying between 10 and 20 miles) depending on traffic loading.
Point of interest (or not), this type of departure flow was referred to as an A.D.I (Average Departure Interval) in the U.K and was very rarely used due to its inaccuracy. Much more common (and I mean MUCH), was the use of M.D.I (Minimum Departure Interval), which specified a minimum amount of time between each a/c departing on that route... Much more accurate for predicting traffic flow but also far more restrictive for the tower controller.
I stand to be corrected on any of the above
Hope it helps, CR

@choclit runway
Thanks. But still not very clear about the "Muscat flow control in place" thing. What extra steps should I take as a pilot. Am I expected to take on some more fuel?
Is all this explained in some publication?

Hi again,
You need do nothing, save sit on stand and take the delay I'm afraid. It's just a measure the centre puts in place to stop us launching too much traffic through their airspace and we will adjust our departure rate at Dubai accordingly. This is simply to prevent controller overload!
The reason we keep you on stand if neccessary is so that you won't need the extra fuel for potentially sitting at the holding point for 40 minutes while we are launching traffic at this slower rate.
No published restrictions because they are so subjective, based on the traffic of the day.
During peak periods it can be frustrating for you, us and the paying punters but think of the poor guy or gal working all the traffic through their airspace without let up. As always SAFE, ORDERLY, and Expeditious comes at the end!
Cheers

Watcha Gonzo,
Agreed! Just a heads-up I guess?
Cheers, hope this has answered your question SS. I do remember reading an AIC on the subject, I think it's number 1 200? should narrow it down enough for you to find it.
