I can understand the higer power thing. After all they will never admit their shortcomings publically but at least they accomodate them and plan for them.
I often wonder why ATC can't up the movements especially with the things to come in the near future. As everyone knows it is only going to get worse.
Something to plan for which will never happen in the middle east is where all the agencies can coordinate the flow into DXB. When Bahrain tells you go 310 kts and then the UAE tells you 250kts when you check in and Dubai puts you in a hold better talking would be a good thing. You will never get the arabs to agree on anything but it is worth a try for better flow.
