Integrating UAS into the National Airspace System (NAS)

The Department of Defense (DoD) is the largest operator of aircraft in the world; this includes having the most experience in Unmanned Aircraft Systems UAS operations. Outside of the Federal Aviation Administration (FAA), DoD is the largest regulator of pilots and aircraft, as well as manager of airspace. “There are three foundational requirements needed for any aircraft (manned or unmanned) to integrate routinely into the National Airspace System (NAS): airworthiness, pilot/operator qualification and regulatory compliance” (USAF, 2012, Slides 4- 10). UAS airworthiness criteria is a critical requirement for gaining NAS access.
Currently, Automatic Dependent Surveillance Broadcast (ADS-B) is available in General Aviation (GA) and military manned aircraft. Research is being done to determine if an Autonomous ADS-B system is a viable technology to be used in UASs (USAF, Slide 19). This system would be used as a sense and avoid tool to help the UAS navigate through airspace and getting traffic reports from other aircraft occupying the same space (manned or unmanned). In addition to ADS-B, the Traffic Alert and Collision Avoidance System (TCAS-II) system may also be a viable option for traffic management and Detection and Avoidance (DAA).

Starting in September of 2011, NASA has been working on a plan to integrate UASs into the NAS. This project aims to reduce the difficulties and technical barriers of introducing UASs into the airspace shared with manned aircraft. The project will conduct system-level tests to address specific safety and operational challenges and concerns of NAS access for UASs. The data gathered from these tests will be provided to customers such as the FAA and RTCA Special Committee 203 (formerly the Radio Technical Commission for Aeronautics) (NASA, 2011). In addition to testing for operational and safety challenges, the project will focus on five specific areas of UAS integration: Separation Assurance, Communications, Human Systems Integration, Certification and Integrated Tests and Evaluation.
