Paper 75 -- The Impact of Severe Weather on Sector Capacity

It is well-accepted that sector capacity is reduced when severe weather is present in the sector. However, no accepted algorithms for calculating the capacity under severe weather impact have been developed. We have proposed methods to estimate the impact of severe weather on sector capacity. These methods introduced three types of weather impact index: 2D weather coverage, 3D weather avoidance field coverage, and flow-based sector capacity reduction ratio. This paper discusses the correlations between the sector throughput and these three sector weather impact indexes with statistical analysis of the historical data. The statistical correlation between the actual sector throughput and the sector weather impact indexes reveals the current operation of the Air Traffic Management system and suggests the acceptable algorithm for calculating the capacity under severe weather impact.
