Hi Check Airman,
I am not talking about company policy but legal requirements. In europe, ATC may report only one RVR on a CAT III, which is totally legal. If more RVRs are reported (which is likely) we have our specific company regulations. But generally, only ONE RVR reported by ATC t is sufficient in Europe. Do you have a data source, where I can find the requirement of having a minimum of two RVRs in the US? Thereis/was one, but I can't find the reference.
Thanks!!
