With the extensive application of sensor technology, airlines accumulate a lot flight data during fleet operations. Quick Access Recorder (QAR) is an important basis for aircraft state estimation and safety assessment, it records operating status various systems. However, current QAR mainly reflected in investigation verification accidents, but fails to apply such continuous real-time monitoring, risk prediction, early warning. Therefore, this paper proposes data-driven integrated warning...
Modern civil aircraft is designed for a greater workload. While the volume of air traffic has grown exponentially over past two decades, total number accidents been flat or slightly higher than averages. However, fatality and property losses caused by aviation are unbearable even if they happen only once. As reported Statistical summary from Boeing in 2019, nearly 40% deaths occurred during final approach landing. A deep-learning-based model accident-type prediction landing was established,...
Purpose The purpose of this paper is to identify the key influencing factors aviation accidents and predict caused by factors. Design/methodology/approach This proposes an improved gray correlation analysis (IGCA) theory make relational find out critical causes accidents. optimal varying weight combination model (OVW-CM) constructed based on gradient boosted regression tree (GBRT), extreme boosting (XGBoost) support vector (SVR) due Findings global accident data from 1919 2020 selected as...
The failure of aeroengine rotor will cause a great threat to the flight safety. A new risk assessment model assess possibility and severity is presented addressing problems that its samples are not sufficient early potential failures easy recognize. key point this determine mechanism with diverse failures, phase, process, historical time, check interval. in state relevant or not. phases divided from initial operational eventually developed functional failure. process confirm possible...
In this paper, an approach has been developed to determine the list of aero-engine life-limited parts (ELLPs) precisely with different number and types for service management plan. The recent researches about ELLPs have investigated including airworthiness regulations life plan based on requirements advisory circulars related from Federal Aviation Administration (FAA), European Safety Agency (EASA) Civil China (CAAC). Take a certain type fan rotor as example, flowchart established through...
In this paper, the relationship with reliability, maintainability, testability, safety and risk related to parts failure have been analyzed. The process of determining collecting important bring catastrophic consequences has established. assessment formed considering man-machine-environment factors, which will decrease loss human aircraft resources.
Safety is the key to airline operations. The premise for ensuring safety valid classification and scientific assessment of hazardous sources. airlines, however, are deficient in an overall mastery effective analysis sources currently. Here, we propose a model risk operations based on constant-sum games, with comprehensive identified by airlines. subjective objective weights source indicators balanced depending optimal coefficients, which determined deriving countermeasure through game...
