Over here in the sandpit, we seem to have this problem mainly in the enroute phase of flight.
Usually when someone doesn't get the level of their choice.
And no, to all you pilots out there, we haven't chopped you off at a level for controller amusement.
When it's busy asking who is the traffic stopping me getting the level of my choice, what is his destination, can I speed up or slow down etc etc isn't going to help the situation.
I understand that you all would like to get your planned levels, but when several aircraft from the same company depart with minimum runway spacing, going into procedural airspace, I'm here to tell you, you will NOT get the same level!
So either give a bit of thought to your departure times, or liase amongst yourselves to decide who wants what, BEFORE you enter our patch. (lets not forget there are other users apart from yourselves).
Muscat is between the rock and the hard place. UAE at one end, Tehran, Karachi and Bombay at the other.
As someone said previously, the conflicting traffic in some cases is not within a bulls roar of where you are now....he will be in 40 minutes though.
Right, off to work!
