You obviously have no experience in low vis requirements,IFR flight plans and chinese Ops.
You are right - I have little experience with low vis and chinese ops. I understand both the pilots and equipment must be rated and current; And realise (just) that flight plans do not seem to distinguish between the various categories of ILS capability.
Genuinely curious: how can they then ensure that flights from from the 10 airports to BCIA be Cat2+ capable other apply restriction on a per-airline basis?
