Non pilot HEMS
Homonculus, in most UK H.E.M.S units, H.E.M.S Crew members/paramedics are a tad more than "amateur map readers/radio changers", they are an integral part of the flight crew involved in not only navigation, but pre landing/take off checks, assisting the Pilot with ILS information and comms with various ground units/control rooms. In my experience, having a paramedic seated in the front does not delay getting the crew to patient at all, as once shut down, we make our way as a crew together to the patient. That said, I completely disagree with allowing non-pilots to fly the a/c.
