LTNman - The ILS for 08 should still be CAT III capable. Aircraft operators need to take into account the lighting available when calculating operating minima. So if approach lights are affected by the development then the detail will be published via Notam or AIP and operators will take it into account when CATIII ILS is available and approach lights are downgraded. During the latter stages of a Cat II or CAT III approach the radio altimeter is used so the ground profile at each runway end may already affect operating minima, so it's possible any slight downgrade of approach lights won't affect this minima..
