Altho AngelFlight is the "umbrella" organization, there are 5 geographic
areas in the US. I live out west and am a member of AngelFlightWest. Each
section has its own minimum requirements for Command Pilot (the PIC).
But I believe the legal issues are pretty much the same (liability
and patient ability). Check out the AFW website for details if you're
not able to get to you local AF website.
