Aeroflop
Not strange at all my friend. The ACC has been telling OMDB to put 10nm in trail spacing between departures at RANBI for as long as I can remember. Besides 10nm is reasonable seen as we find ourselves having 20+ airplanes on frequency during the morning rush on Central. Not kosher!!!
Maybe it's about time you read the LOA then, which STILL states that the outbound flow is 5 miles and parallel headings OK - without coordination, hence the 3 times daily calls to impose "exceptional" flow control measures on Dubai outbounds.
Of course, the LOA could be re-negotiated to limit Dubai outbounds due to lack of the concerned UAE sector's capacity but that is politically unacceptable and the blame would then shift down the road - also politically unacceptable.
