Today's pilots land at major airports in bad weather mainly by putting the aircraft on autopilot, so that the plane locks onto radio signals broadcast from antennas near runways. These signals provide straight-line lateral and vertical guidance. Now, however, the competition among airlines to save fuel and stay on schedule even in rough weather is prompting technologists to look beyond these conventional instrument landing systems (ILS) to technologies that promise ILS levels of precision beyond a straight-line approach. This means, for the first time, aircraft will be able to avoid noise-sensitive areas or mountains and still execute automated landings. Here, Butterworth-Hayes discusses how airlines are vying to find the best mix of precision landing technologies.
