I know this might be a bit ofa tangent...
Here in the US we have SFAR73 - a regulation specifically designed for the R22 and R44 (to try and lower the bodycount)
One of the many stipulations is that no-one may touch the controls unless they have recieved 'awareness training' from a CFI (low-g, mast bumping, low rrpm etc..) and recieved an endorsement. Also no solo before 20hrs.
Are there any similar regs in UK/AUS/NZ/BURKINA FASO etc etc...?
