B777 Alternate Nav
Hey everyone,
hopefully someone knows the answer; I've searched the manuals and can't find it. When you lose both FMC's you still have alternate nav through the CDU's. Providing the adiru is still serviceable its still mnps compliant. But what is the rnav capability, is it still ok for b rnav airspace above FL95…ie rnp 5? What is it certified for?
Cheers.
