The OEM's role
Such is the complexity of the new generation of helicopters that for all but the largest company the provision of a 'post TR course' upgrade is impossible. There are also operational aspects of the training that are beyond most OEM instructors because rightly or wrongly they are not paired with the customer's pilots because they have the right experience. You are just as likely to draw a guy who has only ever operated a twin turbine in an unrelated role and hasn't a clue about the job you do.
There is therefore a conundrum that means that 9 times out of 10 the customer's pilots are taught the basics and only the basics. The wicked thing is that the guy teaching them has also only received an education on the basics. Ergo - the blind leading the blind. 99% of OEM instructors that I have met have never operated in a world where Cat A ops are mandated but that does not prevent them from being tasked to teach them. Many have only passing notion of multi-crew ops and do not teach it well.
Just to make matters worse the authorities will allow complex types to be used for TR conversions without ever using a Level D Simulator. The pilots are then qualified on type despite never having observed ANY system failure in the way it would be seen for real.
It should be the case that helicopters that have sophisticated automation are designated as COMPLEX TYPES and training in the aircraft forbidden. I believe the Australian CAA were considering such a move.
