Effects of Lateral Offsets on the Lateral Collision Risk of the NOPAC Route

摘要

This paper investigates the effect of lateral offsets on the lateral collision risk for the existing NOPAC routes. As a typical case, lateral offsets of 2NM to the right for the aircraft on the predetermined flight levels are assumed for calculating the lateral collision risk. Traffic under consideration is based on the passing frequency values observed in the current NOPAC routes. The results indicate that the estimated lateral collision risk for the assumed scenario is not greater than that for the system without offsets.
