The Hybrid Landing System - An Airline Pilot's View 892377

A viable option for flight operations during Category III weather conditions may prove to be a hybrid landing system, described in the ICAO All Weather Operations Manual as a primary fail-passive automatic landing system combined with a secondary independent guidance system generally understood as Head Up Display. Redundancy for the failure of the primary autoland system is provided through the head up guidance of the secondary system in order to permit completion of the landing manually. Such a combination could provide fail-operational protection at an installation cost that may be significantly less than cost options for traditional fail-operational systems. This presentation will endeavour to explain the viability of the concept.
