PBN Operations

RNAV 5 operations are referred to as B-RNAV, Basic RNAV or RNP 5 on some procedural charts, airworthiness and operational material.

Since 1998, Europe has mandated a B-RNAV capability for operations in European en-route airspace.  The B-RNAV (RNAV 5) is mainly deployed in European area but does not apply over the U.S. airspace.
