GE Aviation is designing and deploying the first required navigation performance-authorization required (RNP-AR) to instrument landing system (ILS) flight procedure in China for Air China Southwest. The two merged technologies will provide more efficient routing and improved access for flight operations at Xi Chang Airport in south-central China. RNP paths rely on satellite-based navigation technology, not ground-based navigation aids.
