Naverus RNP Availability Forecast Service (NRAFS)
Operators using RNP procedures are required to obtain a forecast of RNP availability for intended airports of operation. The Naverus RNP Availability Forecast Service (NRAFS) meets this requirement by providing worldwide RNP availability forecasting -- specific to an operator’s aircraft -- as a means to prevent the dispatch of aircraft when satellite availability of RNP may be degraded. The delivery of NRAFS can be customized to the operator’s requirements, providing seamless integration into existing dispatch systems.
