The Study Of The Mechanism And Control Methods Of ATC Unsafe Events Concerning Humen Factors

As the development of civil aviation and the increase of air traffic flow, air traffic control system the main protector of air traffic's safety is facing a new challenge. Due to the number of unsafe events that cased by air traffic control are increasing year by year and the wild connection between ATC and other fields of study, how to curb the 'headstream' of unsafe events is the key to gain unsafe prevention and enhancement of wholly ATC system's security.The whole article which shows us the distribution of insecurity incidents during the operation of air traffic is based on the analysis of statistic of unsafe events happened this decade. Also the article which associated with current situation of Chinese civil aviation has established an integrated ATC system, and has studied how the three main factors (human, machine, environment) influence the safety operation. Based on the 'accident-due-to' and MMBB theory the article analyze the reason of unsafe event and make a qualitative and quantitative analysis about controller's workload which is the most important factor of work's quality. As a parliament and validation of above research, The real work in Shuangliu APP has been chosen to verify the theory this passage provided, And gain the max workload of ShuangLiu APP could afford; according to the study about the way to control unsafe event and under the guidance of HUMAN FACTOR OF AIR TRAFFIC CONTROL, The article provides assessment of stability of controller's operation include life event analysis the stability of safe operation, also offers the suggestion for different degree of assessment; At last the article set forth the way to control andsettle the unsafe event, and provide the modification for different elements of ATC.
