; (2) develop operational standards and air traffic requirements for unmanned flight operations at test sites, including test ranges; (3) coordinate with and leverage the resources of the National Aeronautics and Space Administration and the Department of Defense; (4) address both civil and public unmanned aircraft systems; (5) ensure that the program is coordinated with relevant aspects of the Next Generation Air Transportation System; (6) provide for verification of the safety of unmanned aircraft systems and related navigation procedures as it relates to continued development of standards for integration into the national airspace system; (7) engage each test site operator in projects for research, development, testing, and evaluation of unmanned aircraft systems to facilitate the Federal Aviation Administration’s development of standards for the safe integration of unmanned aircraft into the national airspace system, which may include solutions for— (A) developing and enforcing geographic and altitude limitations; (B) classifications of airspace where manufacturers must prevent flight of an unmanned aircraft system; (C) classifications of airspace where manufacturers of unmanned aircraft systems must alert the operator to hazards or limitations on flight; (D) sense and avoid capabilities; (E) beyond visual line of sight operations, nighttime operations, operations over people, and unmanned aircraft systems traffic management, or other critical research priorities; and (F) improving privacy protections through the use of advances in unmanned aircraft systems technology; (8) coordinate periodically with all test site operators to ensure test site operators know which data should be collected, what procedures should be followed, and what research would advance efforts to safely integrate unmanned aircraft systems into the national airspace system; (9) allow a test site to develop multiple test ranges within the test site
