Propulsion control with flight director guidance as an emergency flight control system

摘要: The NASA Dryden Flight Research Center has developed a Propulsion Controlled Aircraft, or PCA, system in which computer-controlled engine thrust is used to provide emergency flight control capability. Using this system, F-15 and MD-11 aircraft have been successfully landed without the use of primary controls. However aircraft, not equipped with full-authority digital control, require implementations PCA technology that can be installed on existing systems. Piloted transport simulation studies at Ames examined “PCA Ultralite” concept, provided through combination autothrottle manual pilot aid director guidance. Existing systems were found adequate thrust-only pitch for achieving safe runway landing. level difficulty lateral-directional was vary between aircraft. While certain guidance some regards successful alignment, alternate still need investigated determine if satisfactory performance achieved all capable
