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.

these are, by definition, no longer emerging risks, any more than aviation risks are now. This report examines emerging risks in a more analytical way in order to take practical steps to deal with them and create value for the (re)insurance industry. It places emerging risks in three categories: technical, crystalizing and aggravating.
