摘要
采用雷达管制模拟任务,综合考察两个交通复杂度因素:管制扇区内航空器的动态变化特性,如飞行速度、飞行高度与航向的变化,以及扇区内的航空器数量,及其交互作用对管制员作业表现的影响。结果表明,同管制扇区内航空器的数量一样,航空器的动态变化特性也会显著增加管制员的脑力负荷,降低管制员的情境意识,导致管制员化解冲突的时间延长。研究结果提示,随着飞行流量的稳步增长及空中交通动态变化特性的日趋增强,在采用流量管理、扇区的灵活划分及自由飞行等策略时,应充分考虑航空器数量之外的一些交通复杂度因素。
Four radar control simulation scenarios were. designed to examine the impact of aircraft dynamic characteristics such as change of airspeed, altitude, or heading, aircraft count in the sector, and their interactions on controller performance. The result showed that like aircraft count, aircraft dynamic characteristics produced higher mental workload, lower situation awareness and worse performance. It reveals that with the steady increase of air flow and dynamic characteristics in the sector, more traffic complexity factors should be taken into account when coping strategies, such as flow control, flexible sector partition and free flight are used.
