BUGS/BEARINGS/BOXES
well lets hope thats from 30-50ft max. Coz if its from 4 miles out i would be sceptical about the stble approach criteria being met at eith 500 or 1000ft ( depending on what FR use).
I'd more say that what the person means is actually idle thrust from TOD until finals rather than idle during whole of approach or we'd have more Amsterdam instances ocurring.
