The emergency Services can still do the instrument approach - it's called the Merimbula RNP approach. If the ambulance can't get in from grid lowest safe
the only alternative is a road transport to Merimbula.
Love these changes that send aviation backwards. Like medical flights in Part 135 now have to apply the performance requirements of Part 121, so now
having to factor the landings at 1.43 and 1.67. Wipes out a huge amount of airfields for the King Air 350 - airfields that have been used for eons.
