Safety is the primary task and goal of the civil aviation industry,and airport emergency rescue is an important part of civil aviation safety management.According to the statistics of the International Civil Aviation Organization,more than sixty percent of accidents occur during aircraft take-off and approach and landing phases,and rescue tasks in these two phases are mainly undertaken by the airport emergency rescue team.Airport emergency rescue is a highpressure,high-load,and low rate of fault tolerance operation process.The team often needs to make quick decisions based on the current emergency situation,and the team situation awareness is a great significant factor that affects the decision.Therefore,by constructing a theoretical model of the situation awareness of the airport emergency rescue team,in-depth analysis of the internal mechanism of the situation awareness of the airport emergency rescue team,improving the rescue level of the airport emergency rescue team,and ensuring the safety of civil aviation.Based on the theory of team situation awareness,this study carried out related theoretical discussions and empirical studies.Firstly,the measurement dimensions of team situation awareness are determined,and the characteristics of airport emergency rescue and the influencing factors of team situation awareness are analyzed,and then theoretical research models are constructed.Secondly,based on the theoretical model,an initial questionnaire for the situation awareness of the airport emergency rescue team was designed,and the initial data was pretested,focusing on the analysis and testing of the reliability and validity of the initial measurement items,and the unqualified items were eliminated.Amend the initial questionnaire to get the formal questionnaire.By distributing 202 questionnaires to airport emergency rescue teams in North China,Central China,South China,and Southwest China,the reliability and validity of the questionnaire were tested again,and all items passed the test.Finally,taking an international airport as an example,hypothesis tests were carried out through correlation analysis,regression analysis and mediation effect analysis,and corresponding research conclusions were obtained.The findings of this study show:(1)Task communication has a positive and significant impact on team situation awareness;(2)Team situation awareness have a positive impact on team rescue performance;(3)Team situation awareness plays a part of the mediating role of task communication and team rescue performance;(4)The three dimensions of team situation awareness play a chain intermediary role of task communication and team rescue performance.The conclusions of this study provide theoretical reference and decision support for the selection and training of airport emergency rescue teams. |
