Abstract

The invention discloses a task-oriented aircraft driving man-made error risk assessment method. The method comprises the following steps of task analysis, risk index calculation and man-made error risk fuzzy reasoning. A structured hierarchical task system is generated through task analysis and decomposition, the probability of pilot human errors and generated consequences in the man-machine interaction process are considered, the human error probability, the error influence probability and the error consequence severity are defined as indexes for measuring human error risks, and accurate values of risk indexes are calculated; in combination with specific tasks, the human error probability, the error influence probability and the error consequence severity are taken as inputs, the human error risk is taken as an output, and the human error risk is evaluated through a fuzzy reasoning method according to an input / output logic relationship. According to the method, the problem of result uncertainty caused by subjective judgment of experts and insufficient data can be solved, the accuracy of human error risk assessment is improved, and a basis is provided for prevention and control ofthe human error risk of aircraft driving.

Description

technical field [0001] The invention relates to the technical field of aviation safety risk assessment, in particular to a task-oriented aircraft pilot human error risk assessment method. Background technique [0002] The continuous development of airborne equipment and automation technology has greatly improved the reliability and safety of aircraft, but aviation accidents caused by human errors have not been significantly suppressed. International Civil Aviation Organization research shows that more than 75% of flight risks in civil aviation transportation are directly or indirectly related to human errors. In the complex cockpit human-machine system, factors such as the environment, internal layout, and human-computer interaction methods will cause pilots to make mistakes or errors. However, the probability of human errors in different tasks is different, and the consequences of human errors are also different. If a task has a high probability of human error and has seri...
