This report contains the results of a three-part study relating to development of electronic (fly-by-wire) flight control systems. Flight safety and mission reliability goals for fly-by-wire flight control systems were derived based on a survey of Navy-supplied data on operational aircraft. Electronics augmentation equipment was surveyed to determine achieved reliability on this equipment. Correlation factors were derived for reliability predictions to achieve better accuracy in prediction techniques for electronic systems. Three basic fly-by-wire system mechanizations were studied. Relative merits of each were determined, particularly with respect to monitoring and built-in test functions. Design criteria were developed for a selected configuration. (Author)
