Thanks, I am aware of what RNP is. Just wondering what they mean by mentioning both RNP 12.6 and RNP 20 in the same sentence.
My believing was that RNP and MNPS are to different concepts. And, being MNPS approved, you have sufficient equipment to operate within 12,6 nm of either side of the airway/OTS centre line. In other words, RNP 12,6.
Therefore I am wondering, where comes the 20 nm figure from?
