Conflict Resolution Algorithms for Super Density Operations Impacted by Off-Nominal Events

In this paper we present an approach for resolving conflicts in Super Density Operations (SDO) impacted by off-nominal events. We describe a dynamic routing algorithm in conjunction with a dynamic stochastic route blockage model to predict and efficiently resolve trajectory conflicts in SDO airspace. The proposed algorithms define new flight trajectories that avoid conflicts with off nominal events caused by irregular aircraft behavior or unexpected weather conditions. The paper describes a mathematical model and a set of algorithms implemented in a prototype simulation system. This prototype was used to conduct a series of simulation studies whose results are described and analyzed.
