; (G) the best methods to ensure the safe operation of civil unmanned aircraft systems and public unmanned aircraft systems simultaneously in the national airspace system; and (H) incorporation of the plan into the annual NextGen Implementation Plan document (or any successor document) of the Federal Aviation Administration. (3) Deadline The plan required under paragraph (1) shall provide for the safe integration of civil unmanned aircraft systems into the national airspace system as soon as practicable, but not later than September 30, 2015. (4) Report to Congress Not later than February 14, 2013, the Secretary shall submit to Congress a copy of the plan required under paragraph (1). (5) Roadmap Not later than February 14, 2013, the Secretary shall approve and make available in print and on the Administration’s internet website a 5-year roadmap for the introduction of civil unmanned aircraft systems into the national airspace system, as coordinated by the Unmanned Aircraft Program Office of the Administration. The Secretary shall update, in coordination with the Administrator of the National Aeronautics and Space Administration (NASA) and relevant stakeholders, including those in industry and academia, the roadmap annually. The roadmap shall include, at a minimum— (A) cost estimates, planned schedules, and performance benchmarks, including specific tasks, milestones, and timelines, for unmanned aircraft systems integration into the national airspace system, including an identification of— (i) the role of the unmanned aircraft systems test ranges established under subsection (c) and the Unmanned Aircraft Systems Center of Excellence; (ii) performance objectives for unmanned aircraft systems that operate in the national airspace system; and (iii) research and development priorities for tools that could assist air traffic controllers as unmanned aircraft systems are integrated into the national airspace system, as appropriate
