This was a handy function, because the helicopter have to routinely land in confined inner city places. It replaced a SA 365N Dauphin, registered G-HEMS, in October 2000.

While the MD 902 Explorer is usually a quieter model aircraft than its predecessor, many noise complaints are nevertheless filed relating to HEMS.

The helicopter commonly cruises at 130 knots, at an altitude of 1,500 ft. A frequent fuel load, about 400 kg, will allow for one particular hour””s flying time.
