Essentially what is apparent from this thread is that the ATM procedures/ airspace structure and the EK fuel policy are not compatible with regard to “commit to destination” in DXB. As Ferris says and as many of us have experienced the time airborne from leaving DESDI/BUBIN is indeterminable by ACC and the pilots.
Until a solution comes down from on high we all have to do our best to mitigate the dangers. EK captains should use their experience and authority to carry additional fuel at the times they need it (peak arrival periods) so that they have at least 20 minutes contingency. Dubai approach controllers could help out a lot by providing number in sequence or better still approximate track miles to touch down on first contact.
Blue Sky and other ATC folks thanks for taking the time to post. Dialogue like this is the only way that end-users can understand the restrictions that each work within and can only be to the benefit of all.
Ferris, please don’t lump M5.5 in with us professionals he is an armchair “expert” who likes to pronounce on matters he has very little knowledge of and then does so without much tact.
