Niknak,
The change of an elevation point etc is critical to any aircraft making an IFR approach to an airfield
Someone making an IFR approach to EGHH (which is the airfield Mike referred to) knows that it's Cat1 ILS only otherwise non-precision.
So a one foot elevation change to threshold or ARP makes somewhat less that sweet-FA difference to IFR inbounds in this example.
Maybe if there was less defensiveness and more open dialogue things could actually be improved for everyone - on the ground as well as in the air.
