How TETRA enables mission success
With over 1000 missions carried out by the Devon Air Ambulance Trust, 100s of patients are assisted by the trust's Helicopter Evacuation & Medical Support (HEMS) and critical cars.
Devon’s geography can make getting the right emergency treatment to patients complicated especially in such rural areas where it could simply take too long to reach a patient by a land ambulance. There are also times when a medical team need to be delivered to a scene quickly and then transported with the patient to the best hospital for their ongoing care. None of this would be possible without effective communications.
We caught up with the Operations Manager for the DAAT to find out how they use Chelton’s TETRA services to communicate with each other and other public safety officials and how the critical communications enable mission success.

Using our inherent knowledge and foothold in military air traffic management, Chelton’s RDSFleet has been meticulously designed to work within the complex navel environment using the same features and regulations as air traffic control on land. This hybrid of traffic control is the first of its kind in the world and has been selected for use on the Queen Elizabeth Class aircraft carrier fleet – the world’s most advanced aircraft carrier.  With advanced safety net processing, the RDSFleet takes Air Traffic Safety to a whole new level; providing controllers with an assortment of alerts on Short Term Conflicts, Minimum Safe Altitude and Area Proximity.
Only the best for the best, why was Chelton chosen to supply ATC to the Queen Elizabeth Class Aircraft Carrier?
Displays separated at birth
By far the most prominent characteristic of the RDSFleet is that it has an identical working environment to shore-based stations already using the system. Of course the capabilities differ on and off shore but the displays will remain the same.
Now that I’m here, where am I?
Naval officers wake up in a different part of the world every morning, so it’s important they have the correct airspace on display. The RDSFleet enables the same capability as shore-based systems; the worldwide Digital Aeronautical Flight Information File (DAFIF) data is re-issued and maintained on a monthly basis by the MOD ensuring air traffic controllers, wherever they are, have the latest global mapping data in front of them.
Arrivals and Departures
The RDSFleet is highly adaptable to these different needs and can be configured to support various take-off and landing options including Catapult Assisted Take-Off But Arrested Recovery (CATOBAR), short take-off and vertical landing (STOVL) and Helicopter Platforms.
A T C, easy as 1 2 3
Traditionally, ship-to-shore and ground-to-air communications have been through separate systems but now Air Traffic Controllers can talk to anyone, anywhere through the same system. An identical display and user experience will also reduce the training requirements.
Great Scott!
With the unpredictability of the ocean, you may imagine that equipment can suffer in this environment. Not the RDSFleet. The RDS1600 alone has recorded an impressive 84 million operational hours without a single interruption in service – that’s 95 centuries! In the year 11,521, when flying cars will be a reality not a dream, Chelton will last the test of time with its Air Traffic Control System.
