UK ATC is the best in Europe, bar none, and by some margin too.
The majority of congestion is caused by poor pilot R/T which causes elongated exchanges. ATC stick to the book, if we all stuck to the book too, congestion would lessen dramatically.
UK airspace has many light aircraft flying around in proximity to ILS's. I believe the procedure of not clearing for descent on the ILS until established on the localiser is to ensure that your path ahead will be clear when the descent starts. Makes sense to me.
I just wish ICAO/NAA would agree that a change of one millibar (or even two) is of no interest to anyone, with todays modern aircraft,
Yeah that's real sensible. 1MB is ok, but is another 1, or maybe 2.... Hey, why not just fly 10 knots fast and 10deg left of assigned heading, sure it hardly matters at all really.
