ABSTRACT

A Commercial Aviation Safety Team (CAST) study of 18 LOC-I accidents determined that a lack of external visual references (i.e., darkness, instrument meteorological conditions, or both) was associated with a flight crew’s loss of attitude awareness or energy state awareness in 17 of these events. In response, CAST called for research on Virtual Day-Visual Meteorological Condition (VMC) displays, also known as Synthetic Vision Systems, to accomplish the intended function of improving flight crew awareness of airplane attitude. A NASA high-fidelity simulator research study is described that focused on evaluation of the technology during upset recovery and line operational simulation scenarios with Boeing 787-rated international airline flight crews, which supplements previous studies evaluating the technology with U.S. domestic air transport pilots. The results evinced that synthetic vision systems can significantly enhance recognition of, and prevention of entry into unusual attitudes and aid in recovery especially over high-terrain environments through substantially enhanced attitude and terrain awareness.

摘要

商业航空安全团队（CAST）对18个LOC-I事故的研究确定，缺少外部视觉参考（例如，黑暗，仪器气象条件或两者兼有）与飞行机组在飞行中失去态度意识或能量状态意识有关这些事件中有17个。作为响应，CAST呼吁对虚拟日视觉气象条件（VMC）显示器（也称为合成视觉系统）显示器进行研究，以实现旨在提高机组人员对飞机姿态的了解的预期功能。描述了NASA高保真模拟器的研究，该研究的重点是与波音787级国际航空飞行机组一起在故障恢复和线路运行模拟场景中对技术进行评估，从而补充了先前由美国国内航空飞行员对技术进行评估的研究。
