Abstract

This paper examines the performance of two systems to prevent controlled-flight-into-terrain (CFIT) accidents, including their development and preimplementation issues and attitudes. The airborne version, the Ground Proximity Warning System (GPWS), was required for certain large turbine-powered airplanes. The ground-base system, the Minimum Safe Altitude Warning (MSAW) is a feature of the ARTS-3 system. Accident data from the National Transportation Safety Board (NTSB) and reports from the Aviation Safety Reporting System (ASRS) were used in assessing performance. It is concluded that these systems have dramatically reduced accidents. Although false and nuisance alarms continue, no evidence suggests that they have caused any accident. The tenacity of the alarms--especially the GPWS--as well as appropriate triggering criteria seem to be basic to their success.

摘要

本文研究了两种预防可控飞行撞地（CFIT）事故系统的性能，包括它们的发展情况、实施前的问题以及相关态度。机载版本的地面接近警告系统（GPWS）是某些大型涡轮动力飞机所必需的。地面系统，即最低安全高度警告（MSAW）是ARTS - 3系统的一个功能。评估性能时使用了来自美国国家运输安全委员会（NTSB）的事故数据以及来自航空安全报告系统（ASRS）的报告。得出的结论是，这些系统已大幅减少了事故。尽管误报和干扰警报仍在继续，但没有证据表明它们导致了任何事故。警报的持久性——尤其是GPWS的警报——以及适当的触发标准似乎是它们成功的基础。
