| RNP stands for Required Navigation Performance. It is a method of aircraft navigation that utilizes modern flight computers, Global Positioning System (GPS) technology and innovative new procedures to enable aircraft to precisely fly predetermined paths. RNP ensures accurate navigation performance through continual monitoring, providing alerts if position becomes uncertain (a feature not available with RNAV) Over the last ten years, RNP has been refined for use in airport approach and departure procedures. RNP paths can be designed to reduce flight distances and lower thrust settings, resulting in millions of dollars in fuel savings for an airline as well as noise and emissions reductions that benefit airport neighbors and the environment. Additionally, the accuracy and all-weather capability of RNP can enormously enhance flight safety. The integration of technology, procedures and third parties required for RNP operational approval is a significant undertaking, similar to approval for Category III approaches. Deployment of RNP equipment and training efforts are typically followed by a phased implementation to give regulators confidence in the operator’s capabilities. |
