The Chairman, Subcommittee on Investigations and Oversight, Committee on Science, Space, and Technology, asked us to review a number of issues related to the Traffic Alert/Collision Avoidance System (TCAS). Specifically we were asked to develop information on: (1) pilot's and air traffic controllers' view on TCAS; (2) FAA's actions to address TCAS's problems; and (3) key aspects of FAA's software engineering approach for TCAS, including FAA's plans to verify and validate the system. To obtain information on the status of TCAS's installation and reported operational problems, we reviewed relevant sections of the Federal Aviation Act of 1958, as amended, and FAA's TCAS regulations, as well as advisory circulars and various reports and position papers that provided information on TCAS operations and issues. We reviewed statistics developed by FAA's TCAS Transition Program to determine the number of altitude deviations and inappropriate TCAS advisories reported by pilots and air traffic controllers.
