Ah yes, but this is a single-pilot aircraft and, I am sure, anyone who has done both will agree with me that single-pilot IFR ops, especially in a wheeezing piston-twin, are more challenging than multi-crew, small biz-jet ops and require higher-levels of self management (stands by for barrage). Ideally, this class of aircraft requires instructors with either a) experience of both kinds of ops or b) single pilot experience with kind of aircraft - which is a bit thin on the ground at the moment.
However, I sure commercial operators will be operating multi-crew so, as the legislation stands, trainee crew could be in the sim with an instructor without multi-crew experience.
I'm sure CAE have this in mind when recruiting trainers and, just because the minimum requirements are such, it doesn't mean that is what they are looking for or prepared to accept in instructor candidates.
I think you are correct though, perhaps the legislation needs a bit of a tweak.
