Study on air traffic controllers'situational awareness reliability in emergency scenarios
In order to improve air traffic controllers'emergency response ability,a reliability model of air traffic controllers'SA was constructed from three aspects:air traffic controllers'personal ability,air traffic control task characteristics and air traffic control equipment.Tower control simulation software and SA Global Assessment Technique(SAGAT)were used to measure the air traffic controllers'SA level in emergency situations.Based on BN,SA reliability was quantitatively analyzed to predict air traffic controllers'level of SA,and based on Bayesian inference,the key factors affecting the reliability of air traffic controllers'SA were analyzed.The results show that the reliability of SA of air traffic controllers is positively correlated with the level of SA in emergency scenarios,and the SA level can be predicted by air traffic controllers'SA reliability.The BN inference analysis reveals that the factors with a higher degree of influence and sensitivity to the reliability of controllers'SA were the deployment of aircraft availability time,the accuracy of the control equipment and the controller's memory.The causal chain that has the greatest impact on the air traffic controllers'SA reliability is the deployment of aircraft availability time→mission characteristics→SA reliability.
