事实证明,AOA指标可以防止摊位,尽管试点采用缓慢,但正在获得牵引力。 AOA indicators, proven to prevent stalls, are gaining traction despite slow pilot adoption.

控制失灵事故——最常见的是由摊位造成的——仍是造成一般航空事故死亡的主要原因。 Loss-of-control accidents—most often caused by stalls—remain the leading cause of fatal general aviation crashes. 为降低这一风险,由Mark Korin试点创立的阿尔法系统开发了负担得起的攻击角度(AOA)指标,提供实时反馈,说明机翼如何接近其关键的挡板角度。 To reduce that risk, Alpha Systems, founded by pilot Mark Korin, develops affordable Angle of Attack (AOA) indicators that provide real-time feedback on how close a wing is to its critical stall angle. 与在高负荷情况下可能不可靠的空中速度不同,AOA显示飞机起飞、着陆和机动期间的实际机翼性能。 Unlike airspeed, which can be unreliable in high-workload situations, AOA shows actual wing performance during takeoff, landing, and maneuvering. NTSB和FAA强烈赞同更广泛地使用AOA系统,FA NORSEE的核准允许直接安装,只输入日志。 The NTSB and FAA have strongly endorsed wider use of AOA systems, and FAA NORSEE approval allows for straightforward installation with only a logbook entry. 然而,许多试点在采用该技术方面进展缓慢,认为没有必要。 Still, many pilots have been slow to adopt the technology, viewing it as unnecessary. 随着宣传和融入现代玻璃驾驶舱的力度不断加大,AOA指标作为轻型飞机最有效的安全升级之一,正在获得牵引力。 With growing advocacy and integration into modern glass cockpits, AOA indicators are gaining traction as one of the most effective safety upgrades for light aircraft.
