Precision-Area Navigation (P-RNAV)

Precision-Area Navigation (P-RNAV)


Universal Avionics' SBAS-Flight Management System (FMS) is a key component in Precision-Area Navigation (P-RNAV) approval. P-RNAV is an aircraft level authorization, consisting of several components, including pilot training, installed equipment and operational approval. An  Airplane Flight Manual Supplement (AFMS) statement demonstrating compliance is also required.

What is Precision-Area Navigation (P-RNAV)?


P-RNAV stands for Precision-Area Navigation as defined by the European Aviation Safety Agency (EASA) / Joint Aviation Authorities (JAA). It defines the minimum performance and function requirements appropriate for Terminal Airspace  Area Navigation (RNAV) operations, and includes navigation data integrity requirements and flight crew procedures necessary to meet the requirements.

European states are progressively introducing P-RNAV procedures across the Terminal Areas of the European Civil Aviation Conference (ECAC), making compliance to the P-RNAV requirements more pressing in order to continue aircraft operations without interruption.

The Benefits of SBAS


P-RNAV offers operators benefits including shorter, more direct routes and more precise navigational accuracy in the terminal and approach airspace. More importantly, not complying with P-RNAV requirements will over time, exclude your aircraft from operating in European airspaces.
