RNP (Required Navigation Performance)

Required Navigation Performance (RNP) is a level of precision in aircraft navigation that specifies how accurately a plane must stay on its designated route. Using advanced onboard systems and GPS, RNP ensures the aircraft follows a predetermined path with high accuracy, improving safety and efficiency, especially in challenging or confined airspace. It allows for more precise routing, reduced separation between aircraft, and access to airports in difficult terrain. In essence, RNP enables aircraft to navigate more reliably and safely by meeting specific performance standards, supporting modern all-weather and complex airspace operations.
