Yes rus I too agree with you but, and there is always a but, not all of our pilot are asking for reasonable requests at reasonable times, and as always asking stupid question like, " what's the a/c type ahead", "What speed would you like".
Of course the company doesn't help matters with their stupid SOP's like not being able to accelerate below 5000ft on departure when told "No speed control" and flying at 278kts in the descent, (not that i do). Try that one in the London TMA!
It matters not what the A/C type ahead is, ATC will co-ordinate the traffic, not us, and you assume standard speed until otherwise told. Little things like that will help ATC alot
It's not difficult to be professional, it's what we are trained to do.
Take it easy.
Puff.
