Established in 2016, the DAC operated as a Federal Advisory Committee (FAC) to provide an open venue for the FAA and key decision-makers supporting the safe introduction of Unmanned Aircraft Systems (UAS) into the National Airspace System (NAS). Operated by RTCA as a utilized FAC from September 2016-May 2018, the DAC sought to identify actions for the FAA on how best to facilitate the resolution of issues affecting the efficiency and safety of integrating UAS into the NAS.
