There is an increasing need to fly Unmanned Aircraft Systems (UAS) in the National Airspace System (NAS) in many national security, defense, science, emergency management, and commerce missions. Due to a lack of automated collision avoidance systems, communication technologies, human systems integration, standardized safety and certification, UAS cannot access the NAS routinely. IAI and its collaborator, The Virginia Tech University, have been awarded a follow-on contract to develop a robust tool that seamlessly enables operation and integration of UAS in the NAS The key innovation is ensuring that our tool will meet future UAS traffic demands, by using a mission profile for identifying operations with a socioeconomic component. A generation system translates the overall demand by specifying the origin, destination, times, and routes of each flight expected for UAS traffic. A data warehouse categorizes this information, allowing easy access to the data over the web. Next, a web-based tool will be created to develop estimates of UAS traffic for a typical “day in the NAS,” varying by season, allowing researchers to compile traffic data for any specific day. Finally the IAI team will enhance The Airspace Concept Evaluation System (ACES) to simulate low-altitude and short-range UAS flights and the Transportation System Analysis Model (TSAM) platform to conduct socio-economic analysis of UAS applications, allowing further modeling of UAS missions based on user requirements.
