Severe en route weather is one of the major challenges for both Federal Aviation Administration (FAA) airspace managers and for airline and other airspace users. Uncertainty associated with changing weather patterns and severity, coupled with uncertainty in how airlines and other aircraft operators will react to the changing weather creates a significant challenge for traffic managers (TMs). TMs must decide, with limited information, how best to handle likely imbalances between available airspace capacity that will change over time due to dynamic weather conditions and air traffic demand for that airspace which also is changing over time as different aircraft operators seek to best meet their respective business needs. A planned enhancement to the traffic management automation system, the Collaborative Airspace Congestion Resolution (CACR) capability allows TMs to effectively and efficiently manage airspace congestion in a tactical time frame (0-2 hours). CACR has four key components: it predicts sector demand and its associated uncertainty; it predicts sector capacity including the impact of weather; it identifies the problem; and, it generates congestion resolution plans. The purpose of the analysis was to determine the benefits of using the CACR capability.
