The F-8 Digital Fly-By-Wire aircraft in flight. The project involving this aircraft contributed significantly to the flight control system on the space shuttles by testing and getting the bugs out of the IBM AP-101 used on the shuttles and by helping the Dryden Flight Research Center to develop a pilot-induced oscillation (PIO) suppression filter that reduced the likelihood of pilots overcontrolling the shuttles on landings and thereby creating excursions from the intended landing path.March 5, 1977NASA Photo / NASA photo› F-8 DFBW Project Description
