The results of studies which were undertaken to contribute to the design of digital flight control systems, particularly for transport aircraft are presented. In addition to the overall design considerations for a digital flight control system, the following topics are discussed in detail: (1) aircraft attitude reference system design, (2) the digital computer configuration, (3) the design of a typical digital autopilot for transport aircraft, and (4) a hybrid flight simulator.

A digital flight control system based on microprocessor technology was designed, developed, and flight tested in Princeton's Variable-Response Research Aircraft (VRA). The microprocessor-based digital flight control system works in conjunction with the VRA's existing fly-by-wire control system, and is programmed to provide command and stability augmentation control laws formulated through modern control theory. The initial flight control computer program, CAS-1, provides direct, pitch rate, and normal acceleration command modes. The latter two closed-loop control laws are designed using sampled-data linear-quadratic regulator theory. The computer hardware and software are described and initial flight test results are presented. Flight test results are based on two longitudinal manual control tasks: tracking at altitude and approach and landing. They demonstrate the effects of varying sampling rate, computation delay, and control resolution on calibrated step response and on pilot opinion ratings. It is concluded that the pilot can provide effective control with lower sampling rates and control resolution than might have been anticipated. The limiting values are task dependent, generally lying in the range of 5 to 10 samples per sec and 4- to 8-bit resolution. Flight test results with pure time delay tend to confirm that there is rapid degradation of pilot opinion as the delay increases beyond 0.2 sec.

This report describes a study of flight control actuation system with an objective to determine the degree of digitalization possible between the digital flight control processor and the control surface. A typical analog actuation system is defined as a reference for comparison with five alternates, each mechanized with increasing amounts of digital equipment. The report provides a basis for determining the direction of digital actuation systems. It verifies that distributed actuation systems are now feasible and promise enhanced performance, reliability, and cost reductions.
