Might we be better occupied in trying to address the early descents we all have to endure on entering the UK airspace? I leave you to do the maths, or guess at the figures, but it seems all of us are burning several hundred kilos of fuel to accommodate ATC and their restrictions. I have flown over London LATCC in every conceivable direction to destinations throughout the UK and I have been brought down anything up to 100 miles early to 'avoid conflicting traffic'. Surely if we are all doing this then we are all in each other's way!
Anyone know the definitive reason this must occur?
