Required Navigation Performance (RNP) defines the level of accuracy and reliability an aircraft must maintain along a specific flight path. Based on GNSS data and onboard instruments, RNP ensures that the aircraft remains within a precisely defined navigation corridor. The lower the RNP value, the higher the accuracy, allowing for more precise approaches, especially in areas with challenging terrain or obstacles. RNP standards enhance the safety and efficiency of modern flight operations while complementing GNSS-based navigation systems.
