Sure, I appreciate that but cannot others be suitably modified and used as IR trainers? A JetRanger may be more expensive than a R22 but it's cheaper than a twin!
well I guess its possible, but an operator would have to make a case , get a dispensation (dont know if this would be even possible), spend a whole load of money on adapting it and getting the aadaptions approved, and then find that they can only use it for IR training as it would probably be too heavy to use for VFR charter.
I have done the IR and personally I think flying the an appropiate twin is reasonable (even though the cost is high)
