Pprune Radar,
When was the last time you worked in front of a Radar screen and noticed that the Airbus turns considerably earlier than any other type of acft?
That it is the issue here and not fly by as such.
Of course I know that a waypoint can't be overflown on the spot in every circumstance, but it still makes a difference when it is 10NM before (Airbus) or 2NM before (Boeing).
And BTW I'm not claiming to carry the ultimate wisdom re ATC (must be a NATS thing...).
Spuds (non-NATS and non-UK ATCO, yes, ATC is being done elsewhere too...)
