[Avionics Today 10-14-2014] Garmin and Jeppesen have introduced the RNP AR NavData Service, a tool for pilots using Required Navigation Performance – Authorization Required (RNP AR) procedures. The new service automates data validation processes that are required for business, general and commercial aviation RNP AR flights.

Approved by the FAA, the RNP AR NavData Service automates the data accuracy checks required by FAA Advisory Circular (AC) 90-101A for operators flying RNP AR procedures. Previously, these data accuracy checks were performed manually, which consists of checking 20 parameters on every leg of an RNP AR procedure.

RNP AR procedures provide improved access to select airports in terrain or traffic-challenged conditions. Understanding multiple variables that take aircraft, equipment, and aircrew performance into account supports the evaluation and deployment of previously unattainable flight paths. This process opens access to airports and runways not previously served by instrument approaches and/or the relatively low minima typically offered by RNP AR approach procedures.
