Quantification of midair collision risk for established on required navigation performance operations

摘要

Established on Required Navigation Performance (EoR) (RNP) is an operational concept which leverages performance-based navigation (PBN) to eliminate the separation requirement of 1000 feet vertically or 3 nautical miles horizontally. EoR promises many benefits to the National Airspace System (NAS) such as increased navigational performance, reduced pilot and controller work load, and lower track miles flown. Prior work presented the results from human-in-the-loop experimentation designed to assess these operations and the development of collision risk models that leverage these experimental results. This paper focuses on the application of the models recently derived and interpretation of results obtained. The results indicate mid-air collision risk is between 10^-9 and 10^-10 per operation for simultaneous independent EoR operations to dual parallel runways separated by 3600 feet or greater and to triple parallel runways separated by 3900 feet or greater regardless of whether the turns were designed with TF or RF legs.
