includes the following: (1) Recommendations for preventative measures, including process changes and identification of available technologies, to mitigate the risks of runway safety incidents and accidents at or near airports in the United States. (2) Recommendations for additional airports in the United States, based on a risk-based analysis, that would be viable candidates for installation of runway safety technologies. (3) The FAA's timeline and action plan for replacing, maintaining, or enhancing the operational capability provided by the Airport Surface Detection System - Model X (ASDE-X) and the Airport Surface Surveillance Capability (ASSC) legacy surveillance systems, and implementing runway safety technologies at airports currently without surface surveillance systems, as needed to improve runway safety. (4) An explanation of the decision-making process used by the FAA to determine whether to introduce runway safety technologies, like ASDE-X, ASSC, or other appropriate surface surveillance systems, at additional airports. (c) Briefings Following the submission of the report under subsection (b) and annually thereafter, the Administrator shall brief the appropriate committees of Congress on the progress of the action plan under subsection (b)(3), including on the— (1) status of implementing new surface surveillance systems at additional airports
