Development of All Weather Landing System Reliability Analysis and Criteria for Category III Airborne Systems, Phase III, Volume I

摘要

The Phase III, Volume I, report presents the results of a study program on Category III airborne All Weather Landing Systems. The primary program effort was directed toward the evaluation of reliability, availability, safety, and human factors for airborne systems ranging from Simplex to multi-channel Fail Operative configurations. Included in the report are mathematical models depicting reliability and safety as a function of system configuration and operating parameters. From the Reliability models, a computerized program is generated, presenting the reliability, availability, and safety of the various systems being considered for Category III landings. Also, as part of this program, a Human Factors error analysis was conducted to determine the probability of human error, based on the tasks required to perform a Category III landing. Using the results of the Human Error analysis and the Airborne System Reliability analysis, a safety model was derived that presents the probability of occurrence of a hazardous event. As a result of these studies, data was generated to allow comparison of systems with respect to reliability and safety, and to outline potential problem areas. A Volume II of this report has been published under a separate cover. Volume II contains supplementary data, presented in the form of appendices, developed in support of the analysis presented herein.
