What is B-RNAV in relation to a GPS receiver?
Basic RNAV defines European RNAV operations which satisfy required track keeping accuracy of +-5 nautical miles for at least 95% of the flight time. The term “basic” can be considered to equate to the expression RNP 5 (Required Navigation Performance) which is a statement of the navigation performance accuracy necessary for operation in a defined airspace. Thus N-RNAV = RNP 5 RNAV. Most GPS receivers produced today satisfy this requirement for receiver accuracy. Most older GPS units have software modifications or service bulletins available to bring the GPS unit up to this specification.
