Each critical care team consists of a very skilled pilot, co-pilot, pre-hospital care doctor and critical care paramedic. All are very experienced and skilled in their field. You can learn more about our crew here.

We have two AW169 helicopters. The helicopters are powered by two Pratt and Whitney engines. They also have full single-engine capability allowing them to fly and land with one engine if necessary. The AW169 flies at around 170mph. You can learn more about our helicopters and rapid response vehicles in the ‘Our Impact’ section of our website.

We work in partnership with the East of England Ambulance Service NHS Trust (EEAST) who, according to clinical need, dispatch the EHAAT team from the Critical Care Desk (CCD) based in the EEAST Emergency Operation Centre at Broomfield Hospital. The CCD is manned by a critical care paramedic and a trained dispatcher to ensure appropriate tasking. Once they have completed the pre-flight checks in the helicopter or checked the route and secured themselves in the RRV, the team leaves within minutes of the emergency call being received at the airbase.

Our helicopters and RRVs carry blood products on board. The ability to give a pre-hospital transfusion at the scene of an incident could be a life-saving intervention for patients suffering significant bleeding and blood loss. This early transfusion will significantly reduce the time lost in having to take a patient to a hospital to receive blood. We carry packed red blood cells of blood group O Negative, meaning they can be used on any patient, along with lyoplas, a freeze-dried plasma. The packed red blood cells are supplied daily and replenished as required from The Princess Alexandra Hospital in Harlow and delivered to EHAAT’s airbases at Earls Colne and North Weald by riders from Essex Voluntary Blood Service (EVBS).

The total cost per mission is in the region of £2,800, and the fuel for flying each helicopter on average per hour costs £280.

Without access to National Lottery funding and with only limited support from Government, we rely upon the generosity and goodwill of the people and businesses of Essex and Hertfordshire who make donations and fundraise in order to keep both emergency helicopters flying.
