Area Navigation (RNAV) Explained
RNAV allows an aircraft to fly direct routes between specified geographic coordinate waypoints without overflying terrestrial navigation stations.
Required Navigation Performance (RNP) & Onboard Alerting
RNP is an RNAV specification that mandates On-board Performance Monitoring and Alerting (OPMA). The avionics continuously verify that actual navigation error remains within the defined containment boundary (e.g., RNP 1 = 1 NM).
