Back in the day, if the Co-ordinator was switched on, he would look long range and assign speeds for the inbounds, (eg. first 3 guys less then 10 miles is ok, high speed and direct, then slow down number 4), and as long as the co-od knew what was up, it all worked out fine. Then we get a retarded memo, that we can't call you guys, and co-ordinate individual aircraft.
the instruction i believe you are refering to was issued by dubai due to the ammount of times dubai app would issue flow instructions eg. holds, speed reductions etc when the a/c were overhead/past the point they wanted the speed/hold to occur. ie uae123 overhead desdi, dubai call me on north to hold him at desdi. managed to get him into a hold just past desdi only for duabi then to say no dont hold him bring him in h090, so canceld hold he had just started and turned him right h090 and handed off to app. see the a/c make a 180deg turn and then a/c calls me tracking to desdi to hold. dubai then call back and say changed mind as they have a depature pending and need him to hold for 2 patterns. 100% true. the memo also only came out 6 mths ago, in my time here before then the only flow we tended to recieved was when it had already gone to %$^# in dubai airspace
Then we get a retarded memo, that we can't call you guys, and co-ordinate individual aircraft.
true you are not supposed to co-ord individual a/c but you can look on the big screen and see whats going on, and change the flow rate to suit. ie we only need 10nm until baw12 then 15nm. or the bunch of 10 coming trough from the west we only need 10nm but hold the 2 from the east till time ..... or tell the twr to hold the 2 pending dep on the ground till time .... while you accept 10nm for the next 10a/c etc etc. pilots happy due less delays in the air and happy as they are useing less fuel instead of holding for 30nm spacing, controllers happy as things run smoother giving 10nm instead of 30nm, mangement happy as you are complying with the memo and just adjusting flow rates not giving instructions for individual a/c. sounds a bit better then
Ah forget it, sounds like work
10 miles with both of them coming thru 320 kts?
we are required to give you all a/c 10nm {or 15nm from the east on rwy 30 }in trail when the second passes the gate and all a/c are to be 250ias from the arrivial gate if they are less then 250ias we must co-ord and let you know. so not sure where the 320ias came from.
no its not a perfect system. yes we are beating our heads against a wall trying to get others ie. app, pilots, management etc to understand our point of view. but its very frustrating to read on here how bad a job uae acc do by slowing/vectoring/holding to give dubai such huge spacing when the reason for all that is due to dubai app and the enormous restrictions they put on in the first place.
