Abstract : This paper presents a brief outline of the history of the General Dynamics/Fort Worth Division Production Digital Flight Controls Program. Two flight demonstration programs will be discussed: the single channel digital F-16 and the four channel digital F-16. These were the first flights ever of a microprocessor-based digital fly-by-wire system in a relaxed static stability aircraft. Both demo programs use a pseudo Higher Order Language (HOL) tailored for flight control system applications. This paper describes the technqiues used in applying the JOVIAL J-73 HOL to Digital Flight Control System Operational Flight Program (OFP) mechanization. Results are presented from testing the OFP on flight hardware. Included in this paper are JOVIAL J-73 language issues such as subroutine implementation and their associated efficiencies, the test set, and testing methods. (Author)
