FLOW CNTRL - DXB
Grear idea but must be applied to all traffic inbound.
Holding delay can be absorbed by speed control for those accepting EAT enroute. ACARS arrival flow control clearence acceptance process, like DCL and NAT entry CLR.
If not able to accept an arrival EAT via ACARS then expect to go to the back of the que and wait for a spare slot.
Also need an RNAV arrival from arrival fix, I.e. DESDI. and not the S bend radar vectors at non optimum speeds and altitudes
