; (5) coordinate research and flight demonstration activities with other Federal agencies, as appropriate, and the United States aviation manufacturing community; and (6) ensure that the program remains aligned with the Aeronautics Strategic Implementation Plan, and any updates to the Plan. (e) On-Demand aviation Congress finds the following: (1) Fuller utilization of high-speed air transportation, small airports, helipads, vertical flight infrastructure, and other infrastructure can alleviate transportation congestion and support economic growth within cities. (2) NASA should continue to develop and test air vehicles, different propulsion systems, network systems, unmanned aircraft system traffic management systems, and technology that can be utilized in on-demand air transportation. (3) NASA should actively support the research around the use of airspace for on-demand aviation. (4) This work should leverage NASA’s ongoing efforts in developing advanced technologies for large, high-volume commercial aircraft applications and airspace operations. The Administrator should assess which air traffic concepts perform most efficiently, taking into consideration factors such as existing city infrastructure, small airports, and current airspace operations. (f) Definition of United States company In this section, the term United States company means a private sector entity— (1) organized under the laws of the United States; and (2) that has an existing facility or facilities located in the continental United States, including infrastructure and staffing, capable of meeting the objectives of the program for which the company seeks to participate, as determined by the Administrator. 6.
