I am not clear why they have so explicitly excluded instrument approaches from the EIR. They recognise that there will be situations when such an approach is necessary, hence the emergency training requirement. Why not go the rest of the way and allow add on training to permit legal instrument approaches?
As I mentioned earlier in the thread, I think there's a clear analogy with the instrument training given to PPLs. We make them do a few hours under the hood, even though there is no intention to permit instrument flight as a privilege of the basic PPL. It's for emergencies, not for regular use.
