The idiotic ppl brigade already swim in your waters .... And have done , virtually incident free , for quite some years . It's called an "IMC" rating and is basically the same as an EIR I guess .
You sure about that nigelh? I thought the IR(R) is broadly similar to the UK IMC rating? As far as I can tell the IR(R) enables those so desiring to:
flight in IMC outside controlled airspace, (in Class G) and IFR flight in Class D or E controlled airspace with appropriate permission
So like I said. Keep this outside of Class 'A' airspace thanks.
