P-RNAV and RNP AR / RNP1
Please could You someone describe differences between accuration of P-RNAV and RNP1? What is the main difference? I know that P-Rnav is method and RNP is requirement, but the meaning of accuracy is same. Deviation of flight track no more like 1NM in 95 percent of whole flight. It is same. Thank You,
