Application of Analogous Models in the Safety Analysis of Aircraft Systems

[摘要] The incidents-and-accidents prevention has been receiving an increasing consideration from authorities and aircraft manufacturers. One method to comply with the requirements includes aircraft certification testing of systems—which are usually associated with long time frames and high costs. Besides, they usually demand specialized technical devices and skilled manpower. The use of analogous models to a system might reduce several steps and costs of such test procedures. These models might also contain important information about the tested system to be explored in a risk analysis. This work demonstrates how the parameters of an electrical circuit analogous to a landing gear system on a free drop test can be used as research tools to start a risk analysis based on human factors. The results can be easily grouped and tabulated, allowing us to demonstrate the versatility of the method presented herein and to conclude that this analysis can be expanded into a new area of research on systems’ safety...
