I assume that's a wind up if not, you really haven't got a clue have you?
The reason we think it's a crap idea is it removes flexibility.
Speed control is a major tool used for inbound aircraft. Only a non ATCO would fail to understand that.
Maybe you are a failed ATCO? What was the probelm - inability to be flexible or lack of ability to be able to think for yourself and come up with solutions in an ever changing and fluid environment??
Can you suggest how to merge 3 or 4 streams of aircraft into one orderly line without the use of speed in UK airspace?
These are aircraft that when the streaming commences are in excess of 100 miles from the hold... how the hell is 270Kts or any speed set down by some numpty in an office going to work and how can it be more green if aircraft have to fly for longer?
The speed is just a suggestion, but here's a better suggestion - ignore it.
Blindly following it will reduce controller's capacity and thus drive up delays.
It will also cause unnecessary holding because A/C that could have been high speed to get a no delay approach will often end up arriving at the same time as aircraft approaching the hold facility from other sectors.
270Kts is a stab in the dark speed thought up by someone who has not got a clue about the fact that different types of aircraft have different econ characteristics.
