Prediction of Human Error Probability in Air Traffic Control Safety Accidents Based on THERP Model

Implementing efficient and accurate human error probability prediction for controllers is of great significance for maintaining air traffic order and controlling risks. The THERP method has the function of qualitative and quantitative analysis, which can model the conflict resolution process of controllers and roughly calculate the probability of human error behavior. Through the analysis of a typical conflict resolution error case by a controller, it can be found that THRERP can conduct more detailed analysis, and the resulting data is more guiding for the development of risk control measures.
