I have lost count of the jobs where procedural IF - esp ILS was the only way to either get home or get the casualty to hospital.
ISTR the SH force, esp Chinook and Merlin have been doing procedural IF for many many years and I don't think that was about licences - more about professional capability and being allowed into big boys airspace where PARs don't exist.
The RN never had the kit fitted to their Sea Kings hence no Procedural IR - however, I believe Culdrose is finally having an ILS installed.
There will be a few people who will miss the Chivenor ILS/DME when the flight closes and the kit is moved elsewhere (police, AA, AW etc)
