The Flight Simulator for Advanced Aircraft FSAA at Ames Research Center was used to evaluate the flying qualities of a small jet transport and those of a derivative model of that airplane. The objective was to define technical criteria that piloted simulations must meet to enable their increased use for demonstrating compliance with transport category aircraft airworthiness requirements. Flying-qualities data were obtained for numerous test configuration and conditions using conventional certification flight test procedures. These data correlated well with the basic airplane data from the manufacturers certification test report. Analysis of the simulator data showed valid results in critical test cases, such as the demonstration of static longitudinal stability and minimum control speed, with confidence that all influencing and limiting factors were identified. An important aspect was the accurate simulation of the control force-feel qualities of the reversible flight control system. The simulator was judged to have duplicated actual flight results with a high degree of confidence. It is concluded that it is technically feasible to pursue the increased use of simulation in conducting derivative airplane certification evaluations of the scope reported in this report.
