Area navigation (dashed line) vs. navaid-based navigation (solid line). Area navigation (RNAV) is a method of instrument flight rules (IFR) navigation that allows an aircraft to choose any course within a network of navigation beacons, rather than navigate directly to and from the beacons.This can conserve flight distance, reduce congestion, and allow flights into airports without beacons.rea navigation (RNAV) is a method of instrument flight rules (IFR) navigation that allows an aircraft to choose any course within a network of navigation beacons, rather than navigate directly to and from the beacons.
