The Boeing-Bendix Automatic Landing System has been certified by the FAA for visual touchdowns as a first step toward 700 ft RVR operations. To obtain this certification, the flight test program had to solve several operational problems in order to meet rigid FAA requirements. All reasonably possible failures, including hardovers just prior to touchdown, were introduced during the approach. Performance had to be tailored for satisfactory results on noisy ILS, as well as Category II facilities.
