They may not be assessed to IR minima, but I bet you after 40 years of holding an IMCr a person could fly a stabilised ILS down to minima! Actually flying an ILS to minima, is, should I be so bold as to say, easy in calm non convective conditions, if the approach is stabilised early on - which it should be anyway. This means knowing your aeroplane, the power settings etc..
Still interested to know if ICAO IR holders will be given credit towards the EIR?
