Helicopters and Towplanes

Need assistance in finding a FAA or other reference to "best practices" for
helicopter autorotation practice at active airports.

Recently a helicopter practicing an emergency practice autorotation descent
over the middle of an airport in Florida had a mid-air collision with a
towplane during aerotow takeoff at 100' agl. Towpilot seriously injured but
will recover. Helicopter instructor and student walked away. Both aircraft
totalled. Glider pilot released and landed safely.

Seeking guidelines from the helicopter community that may prevent this from
occurring again.
