Oh dear Finals.
My point was not that the pilots of scheduled/charter airlines (most of whom I think u will find ARE flying IFR
) should not look out of the window, rather that it should not be the prime method of ensuring that there are no lumps of metal in front/below/above of them. Not a wholly unreasonable view?
RAS to IFR is a minefield of liability to ATCOs and ATS providers. CAS D (or A)is there for a reason. We wish to provide a safe operating environment. If that means, unfortunately, a GA a/c can't have exactly what he/she wants: so be it. It is in the interests of safety.
We do try our best.
