As if the FL130 / 250Kt restrictions don't drag out the whole approach anyway we have this 185Kt rubbish miles from the threshold.
As said previously it's only applicable when on a managed approach. I'd still ask of the controller to have the restriction removed for a more sensible speed.
I believe I read something about it in a recent crews news in the Operations section. It seem's to fit in nicely with our soon to be new SOP's to cater for the lowest common denominator in CX.
