This describes the initiative to introduce a capable yet affordable Flight Operations Quality Assurance (FOQA) program into the general aviation industry. A brief overview of the FOQA concept is given along with a historical perspective to the evolution of such programs. Initial development of a FOQA program for general aviation by the Center for Sensors and Sensor Systems at Saint Louis University is introduced herein. A brief discussion of the obstacles in developing such a system is presented, as well as strategies for overcoming these obstacles. The system consists mainly of a quick access recorder (QAR) that is conceived to be a stand-alone, non-intrusive system that collects parametric flight data, a preprocessor system to analyze initial data sets and validate their use, and post-processor software used in the analysis of available flight parameters. The program concepts are presented for initial determination of the needs and possibilities, and examples are presented along with flight data collected in the University's fleet of aircraft. 相似文献

Functional partitioning, redundancy structure, internal communications, and software modularization define the architecture of a digital automatic flight control system (DAFCS). Selection of a suitable system architecture for commercial transports involves such factors as the functional scope, growth provision and flexibility requirements, sensor interfaces, the aircraft's actuator and control surface redundancy, and the dispatch reliability requirements. Trade-offs concerning these various factors are discussed, and it is shown that a very versatile and almost universal DAFCS can be configured to meet the general and peculiar needs associated with each aircraft application. Specific results associated with this system's recent demonstration flights in the DC-10 aircraft, as well as examples from several other transport aircraft applications of the same DAFCS architecture, are used to illustrate the design concepts. 相似文献

The demand for digital cartographic data and information is expanding rapidly, most dramatically in navigation. Electronic chart and map display systems are now reaching the market for land, sea and air navigation and rapid delivery of the latest data is absolutely essential. Commercial aviation is moving rapidly toward the automated cockpit with the new generation Flight Management Computer System. Marine navigation is experiencing a similar growth in integrated navigation systems and every major automobile manufacturer has plans for digital map navigation systems. The largest, most complete data bases to meet these requirements are Government held and difficult to access, thus most private sector firms re-digitize and agencies maintain near duplicate data. Present inefficiencies, introduced errors, and delays stem from lack of rapid access and delivery of digital data. Use of newly developed satellite data broadcast technology offers a solution. 相似文献
