A little bit of a problem there.
In the case of a SAR aircraft working with mountain rescue, lifeboat or aux coastguard Marine FM band is used on Zero or the LandSAR calling channel.
In all other cases, Airwave (TETRA. Like Nodnett.) is expected to be the method for Air/Ground comms.
Murphy's Law, Airwave section, para one
states that when the terrain in particular makes it really important then there won't be coverage.
Para two states that when enough emergency service personnel turn up to substantial rural incident scenes they overload the cell and the system isn't available.
Para three states that aircrew don't enjoy punching long numbers and checking talk-groups during the approach to challenging unsurveyed landing sites.
