If you're operating into class D,E,F,G airspace,then there is a speed limit of 250kts below 10000ft.With modern radar systems we can put the ground speeds on the targets and see roughly whats what.BA will normally ask to keep high speed.Ryanair just do it.
The ones that are tanking around over 250kts are tricky to vector on the ILS.Even though you turn them earlier,they still go through the localiser,as they are too fast.
Helicopters are a whole different thing.Get behind them,which is all the time at ISZ and it's 160 til 4 early.Just the joys of working here.Ain't the pay thats for sure..
