Sorry, I don't have (or know) a concise explanation of the relationship
between the RNAV requirements and RNP requirements. I was just pointing out
a recent change. Here are some references.

Ror RNAV 1 and 2 then, can you explain what the 1 and 2 mean, and any
relation to RNP 1 and 2?

Was I dreaming? Or did I once hear that RNP 1 and 2 stars/sids had
been published in the USA? I see type A and B, but these are RNAV,
and so must have no RNP requirement whatsoever, and can be flown by
any /G aircraft. Anyone provide some info?
