空中交通预警与防撞系统(TCAS)风险及对策研究

空中交通预警与防撞系统TCAS对飞行安全非常重要,它能够通过对附近的飞机进行冲突检测,预测未来可能发生的危险,提示飞行员避免危险,帮助机组维持与其他飞机之间的空中交通安全间隔;但TCAS本身依然存在风险;在此对TCAS进行了半物理仿真测试,包括数字样机开发测试、物理样机开发测试、虚拟试飞以及数据统计分析等,对其各项功能进行测试与验证;在参阅众多相关文献的基础上,结合所做的研究工作,讨论了TCAS的主要风险,并针对这些风险,提出TCAS在设计、测试、操作方面需要改进的地方,从各方面完善TCAS,降低其风险,进一步保障飞行安全。

Research of Traffic Alert and Collision Avoidance System (TCAS) Risk and Countermeasure

Traffic Alert and Collision Avoidance System(TCAS) is very important to flight safety,it can instruct the pilot to avoid the danger through detecting the nearby aircraft conflict and predicting potential hazard in future,to help the crew maintain the safety interval with other aircraft.However,there would be risk on TCAS itself.We do some test on TCAS,including digital prototype test,physical prototype test,virtual test and statistical analysis,to verify its various functions.Refer to lots of relevant literature,combined with research work we have done,we discuss the major risks of the TCAS,and aiming at these risks,we proposed some aspects to improve in the designing,testing,and operating of TCAS,which help to reduce its risk,to further assure flight safety.
