管制员工作负荷已成为制约航空运输进一步发展的关键因素之一,有效的管理管制员工作负荷对确保空中交通安全意义重大。考虑单纯使用扇区流量评价管制员工作负荷的不足,以扇区复杂性因素作为管制员工作负荷的测评指标;通过设计并实施管制运行仿真实验,获取相关运行参数数据;分别构建基于扇区复杂性因素及单纯扇区流量的管制员工作负荷评估模型并予以对比分析。分析结果显示,较之单纯使用扇区流量,基于扇区复杂性因素的评估模型其评估效度优势明显。 相似文献

The air transportation system has a critical impact on the global economy. While the system reliability is essential for the operational management of air traffic, it remains challenging to understand the network reliability of the air transportation system. This paper focuses on how the global air traffic is integrated from local scale along with operational time. The integration process of air traffic into a temporally connected network is viewed as percolation process by increasing the integration time constantly. The critical integration time TP which is found during the integration process can measure the global reliability of air traffic. The critical links at TP are also identified, the delay of which will influence the global integration of the airport network. These findings may provide insights on the reliability management for the temporal airport network. 相似文献

The comparison of pilots' and controllers' goals and situation awareness information requirements has revealed many parallels at the higher levels. At the more detailed, lower levels, however, subtle underlying differences were identified that lend insight into their decisions. The preliminary experimental results indicate that situation awareness was improved when information was shared between the cockpit and the ground. Pilots' traffic situation awareness improved when traffic information was displayed; controllers' weather situation awareness improved when weather information was displayed. Operational errors were reduced in the process. Pilots and controllers also exhibited behavioral changes. When information was shared, controllers provided more frequent weather advisories to pilots. Pilots and controllers were more likely to suggest preferred route amendment alternatives to their counterparts, and re-route negotiation increased in the process. Based on these preliminary results, it appears that shared information between flight crews and air traffic controllers may be beneficial in terms of improved situation awareness and the behaviors it appears to foster 相似文献

The Global Positioning System (GPS) has been used in many ways which were unimagined by its original planners and implementers. This paper discusses one such application; the surveillance of commercial aircraft in a developing airspace environment. GPS provides system users with the ability to determine their own position with an accuracy, reliability and cost that is unprecedented. Voice procedures augmented by radar have been the primary tools for air traffic surveillance since the end of World War II. But for some countries the equipage of aircraft with GPS and a data link capable of carrying position reports to the ATC authorities is providing a viable alternative to long-range secondary radar systems. In the summer and fail of 1995, ARINC installed and demonstrated equipment in Magadan, Russia which permits air traffic controllers of MagadanAeroControl to monitor GPS position reports generated by aircraft as far away as Canada and the South Pacific. The position reports were displayed against maps and flight tracks. This equipment has clearly demonstrated an alternative technology for the upgrading of the ATC system in Siberia and other remote areas 相似文献
