Geoffers; with service level agreements now mostly agreed, maturing air desks in most regional control rooms and 'airwaves' comms providing instant flexibility, the UK charity hems world is moving out of its parochial 'turf wars' age into a responsive era of regional support.
For example the East Midlands Ambulance Service and surrounding Ambulance Services can call upon local air ambulances funded by the people of many different nearby counties, to fly to incidents anywhere in the entire area those Services cover. In a large scale incident anywhere in the Midlands, up to 7 HEMS helicopters could be on scene within 30 minutes, if required. All coordinated temporarily from the airdesk of the nearest controlling Ambulance Service.
