Otherwise you will be getting 20 departures over DARAX all at one time, because the LIDO computer said so.
Don't want to rain on your parade pos-rate...BUT because EK don't seem to grasp the fundamentals of procedural control, there is a 5 minute flow restriction on DARAX departures...that means your number 20 is going to be sitting on the tarmac for an hour before he gets airborne.
So I guess that yes indeed you guys DO need a liaison, to learn stuff like that.
The reason that you get away earlier is through the hard work and professionalism of the UAE controllers helping out the Dubai guys.
Someone has already pointed out, Dubai tower start up loads hoping that there will be a relaxing of Flow restrictions. Sometimes it just won't happen no matter how much they want it.
The guy doing the DARAX rush is also the guy doing the Eastbound departures AND the inbound MAXMO stuff...oh yeah, and the BUBIN stack and low level overflyers, RAK and FUJ ins and outs. But apart from that, he basically sits on his a$$ and does crosswords
The EK boys definitely should come on down to Ab Dab and see what goes on, they will be made more than welcome, especially at the busy times of the shifts.
