Automatic Landing in Bad Weather Conditions

摘要

The use of automatic landing has developed considerably, with the objective of reducing meteorological minima in order to increase flight regularity. At the present time, most systems are limited to values of mean wind announced by the control tower, which does not allow the system to be used in very rough weather; the pilot thus has to manage by himself. An interesting course is to promote automatic landing in all weather conditions, including very high wind. This course was opened up by Lockheed on the L.1011 which is equipped with a system called direct lift control which acts directly on the lifting surfaces and enables the aircraft to content with turbulence and windshear far more efficiently.
