Mmmmm BOLLOCKS!
1. I dont believe Bristows BH206 trainer is allowed into IMC. It can operate under IFR only (i.e.training) in VMC .... and yes there IS a difference!
2. In Australia you can not go IMC without being IFR (except inadvertantly)... especially 115 nmls out to sea. And to be IFR you MUST be able to remain above LSALT with a powerplant failed. LSALT offshore is 1500' and the B206 will NOT do that even with a "dodgy AFCS"!!!!!
3. Anybody who has any real HELI IFR experience WILL NOT WANT TO FLY S/E IFR (in IMC) in anything other than a REAL twin, ie decent sized engines AFCS with decent OEI performance at the LSALT !
