B-RNAV (Basic Area Navigation)

Also known as “RNAV-5”, it refers to an aircraft’s Area Navigation (RNAV) ability for continental en-route operations. An LOA is not universally required, but is highly recommended. The LOA that authorized users for B-RNAV (and P-RNAV) labelled B034, has been decommissioned as of February 2020, for Part 91 -US registered aircraft.
