Unmanned Aircraft Systems (UAS) can perform important missions in national security and defense, emergency management and in scientific and commercial applications. Currently UAS cannot routinely access the National Airspace System (NAS) due to a lack of automated separation assurance integrated with collision avoidance systems, robust communication technologies, robust human systems integration and standardized safety and certification. Technologies and procedures for enabling seamless operation and integration of UAS in the NAS will be useful in the future when tens of thousands of military UAS deployed abroad are brought back. To address this, IAI and its collaborator Virginia Tech University, have been awarded a contract entitled “UAS Demand Generation and Airspace Performance Impact Prediction.” The key innovation is developing a technology with three parts, to generate credible future demand for UAS vehicles. The first is a mission profile system for identifying and specifying civilian UAS trips given their missions. It is an activity-based modeling system that translates inchoate mission profile information into overall demand between city pairs and counties for UAS aircraft. The second part is a demand generation system that translates the overall demand into specific flight data sets, specifying origin, destination, scheduled departure and arrival times and type of aircraft. The final part is a data warehouse that will store flight data sets, and which can be accessed by aviation researchers worldwide for conducting custom studies of UAS impact on the NAS.
