The job of safely managing air traffic in the United States is becoming increasingly complex. In May 2000, the FAAs Technical Center reported: Our air transportation system has over 17,000 landing facilities, 226,000 registered aircraft, 700,000 pilots, 8000 tower controllers, a multitude of terminal buildings and access roads, and 500 million passenger enplanements each year. FAA forecasts predict major growth in demands upon the system. / Availability Note: Product reproduced from digital image.
