A new air ambulance which can operate at night has arrived ready for action.

The MD902 Explorer, an updated version of the charity's existing chopper, will be based at Redhill, in Surrey.

It will be ready for night flying for the Kent, Surrey and Sussex Air Ambulance in late summer.

In preparation for working 24 hours the specialist doctor and paramedic crews have already begun to deliver a medical service using an emergency response car through the night.

Adrian Bell, chief executive of the Kent, Surrey & Sussex Air Ambulance, said: ‘We believe that there is a real and identifiable need for the skills of a specialist medical team during the night as well as through the day.

“To this end, we have replaced one of our helicopters with a new version capable of night operations.

"While we are waiting for the necessary regulatory processes to be completed we have started operating by car during the hours of darkness.

“This has been a very useful exercise in helping us to prepare for a 24-hour operation and has allowed us to learn more about the technicalities and logistics of operating at night without the incumbencies of aviation issues.”

The Kent, Surrey & Sussex Air Ambulance has helicopters based at Marden and Redhill.

The helicopter at Marden will continue to operate during daylight hours and is expected to be replaced with a night flying capable aircraft within the next 18 months.
