ABSTRACT

In order to reduce the level of insecurity and prevent major accidents, screening alarm events for each flight is to prevent and control the ground risk of major safety incidents, prevent the occurrence of major accident symptoms, and provide prompt information for immediate disposal through the application of the algorithm. The risk level of an alarm is measured by analyzing how many alarms will be generated after an alarm occurs. For each flight alarm event, we propose a joint flight operation risk analyzing method, which estimates the possibility of flight insecure event according to the number of system alarms during a certain time. According to the one-month alarm statistics of a certain flight by the flight monitoring system, combined with the self-defined flight risk analysis alarm filtering algorithm, timely early warning is successfully issued in low-oil accidents and runway events, providing all the space and time for dealing with events (such as incidents) in order to raise the company's attention to key events.
