Fully electrical fly-by-wire flight control systems will stabilize the aircraft and enable the pilot to directly control a predetermined flight parameter. The necessary control surface deflections will be determined by an on-board computer. For such advanced aircraft it is imperative to investigate whether existing handling qualities criteria can still be used for the design of primary and backup system, and particularly, whether guidelines are required to cover the change introduced when a failure occurs and the flight control system reverts to a backup system with different characteristics. In international cooperation between research institutes of France (ONERA), Germany (DFVLR), United Kingdom (RAE), and the Netherlands (NLR), an experiment has been defined and executed on the NLR moving-base flight simulator to provide a basis for these guidelines. Emphasis of this experiment was put on longitudinal handling qualities. In October 1987, test pilots from these so-called GARTEUR countries each evaluated 2 primary and 2 backup systems during a 3-day period in 2 levels of environmental disturbances. 收起
