Piloted Simulation Tests of Propulsion Control as Backup to Loss of Primary Flight Controls for a B747-400 Jet Transport

摘要: Partial failures of aircraft primary flight control systems and structural damages to during have led catastrophic accidents with subsequent loss lives (e.g. DC-10, B-747, C-5, B-52, others). Following the DC-10 accident at Sioux City, Iowa in 1989, National Transportation Safety Board recommended 'Encourage research development backup for newly certified wide-body airplanes that utilize an alternate source motive power separate from used conventional system.' This report describes concept a propulsion controlled (PCA), discusses pilot controls, displays, procedures; presents results PCA piloted simulation test evaluation B747-400 airplane conducted NASA Ames Research Center December, 1996. The purpose was develop evaluate throughout full envelope including worst case scenarios engine out trim moments. Pilot ratings performance ranged adequate satisfactory. performed well unusual attitude recoveries 35,000 ft altitude, fully coupled ILS approaches, single failures, aft cg. primarily limited by out-of-trim
