对最近的客机事故和事件的分析确定了一类事件，在这些事件中，结构、机械和电子健全的飞机通过飞行阶段的最低安全运行速度减速到摇杆激活速度。尽管事件的顺序不同，但一部分事件和事故有一个共同点-自动化不再主动控制空速目标。本文描述了事故场景和对主飞行显示器上的空速带进行修改的设计，以明确地通知没有主动速度控制。一项评估增强空速带效果的实验表明，飞行员的反应时间更快，但正确的飞行员反应没有差异。
Analysis of recent airliner accidents and incidents identified a class of events in which structurally, mechanically, and electronically sound aircraft decelerated through the minimum safe operating speed for the phase of flight to the stick-shaker activation speed. Despite the differences in the sequences of events, a subset of the incidents and accidents had one thing in common – the automation was no longer actively controlling to the airspeed target. This article describes the accident scenarios and design of a modification to the airspeed tape on the primary flight display to explicitly annunciate the absence of active speed control. An experiment to evaluate the efficacy of the enhanced airspeed tape showed faster pilot response time but no differences in correct pilot response.
