The complexity analysis tool will also be very useful in establishing capacities for dynamically-generated sectors for FAA FlexAirspace. In addition, results of research studies that we will publish in reports, conferences, and journals may also help shape the FAA plan for migrating from today's MAP-based capacities to complexity-based capacities. The most likely Phase 3 activities involve further development of the complexity analysis tool and underlying statistical capabilities to support NASA's continued aeronautics mission. The complexity analysis tool could be used within field trials throughout the NAS where the complexity procedures may be refined and actual benefits may be measured. Mosaic ATM has conducted field trials of this type previously with other automation tools and concepts and is well qualified to complete these Phase 3 objectives with minimal risk. The proposed SBIR has two primary focuses. First, we will deliver a complexity analysis tool to NASA so that NASA researchers can conduct their own complexity-related research. For example, NASA researchers can introduce new complexity factors and see if the factors are supported by the operational data. In addition, researchers involved with HITL experiments can leverage this capability to simplify the arduous post-processing of complexity-related data. Second, we will perform specific research studies to complement NASA's internal projects. Studies we perform using the complexity analysis tool will be directly useful to NASA. The study results will guide subsequent NASA research studies. The technical approach may re-used by NASA or may influence the approaches NASA takes on future projects.
