There is a majority (but not universal) feeling that the ATC advisory "180 kts to 5nm"/4-degree approach was a possible contributory factor.
I am sure that ATC did not impose this as a whim, in fact a couple of people have indicated that it is a common call for noise abatement reasons.
Well, where does that policy come from ?
Is it an airport operating requirement ? Is it just something that they would prefer ?
