民用飞机信息重构技术性能分析

大尺寸显示器已经广泛应用于新一代民用飞机的驾驶舱内。虽然通过提高信息集成度能够提升飞行员的用户体验,但是,正因为其要求的系统集成度高,在发生局部失效时,容易导致集成显示信息的共模失效,加之信息布局对管理操作任务的性能有着重要影响,如果诱发工作负荷的增加,在特定场景下甚至会迫使飞行机组丧失必要的任务情景意识。信息重构技术是应对此类问题的重要手段。在民用飞机机组资源管理理念的指导下,根据飞行机组的职责分配和人机工程学要求,论述了在主仪表板布置4块15 inch正屏显示器的布局是一种具有比较优势的布局方案。从关键飞行场景下飞行机组的操作任务需求入手,基于正常操作流向保持、压缩格式、重构操作、以及职责分配一致性这4个评价信息重构性能的要素,通过对比分析,证明了所提的显示管理策略相较于某现役先进机型具有更优的信息重构性能。

Performance analysis of information reconfiguration technology on civil aircraft

Large-area display have been widely used in the cockpit of a new generation of civil aircraft. Although improving the information integration can improve the pilot's user experience, the high requirement of system integration is likely to cause the common mode failure of integrated display information in local failure. Since the information layout has an important influence on the performance of operation task management, if the increase of workload is induced, the flight crew may lose the necessary situational awareness in specific scenarios. Information reconfiguration technology is an important means to deal with such problems. Based on the management of crew resource in civil aircraft, the duty allocation of the flight crew, and the requirement of ergonomics, a 15 inch square-screen display on the main instrument panel is proposed as a layout scheme with comparative advantages. Starting from the flight crew operation task requirement under the critical scenario and based on the consistency of normal operation flow, compact format, reconfiguration function operation, and consistency of duty allocation, It proves that the display management strategy of this paper show a better information reconfiguration performance than the advanced reference aircraft through comparative analysis. At present, few articles have systematically analyzed and summarized this topic.
