operation of civil supersonic aircraft and supersonic overland flight. 212. Electromagnetic spectrum research and development (a) In general The Administrator shall conduct research, engineering, and development related to the effective and efficient use and management of radio frequency spectrum in the civil aviation domain, including for aircraft, unmanned aircraft systems, and advanced air mobility. Such research, engineering, and development shall, at a minimum, address the following: (1) How reallocation or repurposing of radio frequency spectrum adjacent to spectrum allocated for communication, navigation, and surveillance may impact the safety of civil aviation. (2) The effectiveness of measures to identify risks, protect, and mitigate against spectrum interference in frequency bands used in civil and commercial aviation operations to ensure public safety. (3) The implications, including risks, of new or emerging technologies or other factors on the environment for radio frequency spectrum interference. (4) How various new or emerging technologies may enable improvements in the prevention of, mitigation of, or resilience to interference, including the ability to sense the spectrum environment and dynamically change frequency to ensure resilient operations. (b) Report Not later than one year after the date of the enactment of this Act, the Administrator shall submit to the appropriate committees of Congress a report containing the results of the research, engineering, and development conducted under subsection (a). 213. Aviation structures, materials, and advanced manufacturing research and development (a) In general Using the amounts available under section 48102(a) of title 49, United States Code, the Administrator, in coordination with the Director of the National Institute of Standards and Technology, shall carry out a research and development program for advancing aviation structures, materials, and manufacturing for the safe use in and on aircraft. (b) Inclusion The program under subsection (a)
