ILS
Spending an additional 2 minutes in the hold is better than having to divert.
What prevents an aircraft from being cleared beacon outbound for the procedure provided it remains at least 1000ft above the missed approach altitude until such time as the preceeding has landed.
Timing will be of the essence to ensure the lander has vacated the main before the second ac commences the base turn.
Politics or not, the ILS will be very useful this winter.
