Ref the Rj's out of KK, we can give you a good rate if we maintain 210kts, but that means not levelling at 4000ft otherwise we will accelerate, If i get cleared to 6000 on initial contact i will always give best rate, saves us time too. If we level at 4 or 5 I generally assume that you are busy and accelerate. Did an ABZ yesterday and was FL75 by abeam the Take off end of 26L and got a lovely short cut. The other thing is we cant accelerate past 250 until Fl80 but once we have got 300kts we can trade speed for height if you need it, just ask.
We'll all be in the regions by April so wont be too long anyway. We only get to know what you want by these boards, it would be great if there was more communication between ATC and Crew. I'm sure if a preci of your standing instructions out off kk was on the board we would read it.
