For most EMS, IFR as it is currently configured is worthless. You simply can't do an IFR approach to an unprepared scene. Nor can you fly an approach to the hospital. I often fly to scenes 5 miles or less from my depaarture point. IFR simply won't work, even if I had an IFR capable aircraft. That isn't the answer. An autopilot, and proper TAWS and TCAS might help, but I have the TAWS, mostly, in the GPS. I don't have a good answer to preventing all the EMS accidents, I do know that IFR is not the answer. It can work for some transfers, but I do mostly scene work, and IFR simply isn't possible.
