The associations of pilot error with the type of flight operations and basic weather conditions are well documented. The correlation between pilot characteristics and error is less clear. This study aims to examine whether pilot age is associated with the prevalence and patterns of pilot error in air taxi crashes.
Investigation reports from the National Transportation Safety Board for crashes involving non-scheduled Part 135 operations (i.e., air taxis) in the United States between 1983 and 2002 were reviewed to identify pilot error and other contributing factors. Crash circumstances and the presence and type of pilot error were analyzed in relation to pilot age using Chi-square tests.
Of the 1751 air taxi crashes studied, 28% resulted from mechanical failure, 25% from loss of control at landing or takeoff, 7% from visual flight rule conditions into instrument meteorological conditions, 7% from fuel starvation, 5% from taxiing, and 28% from other causes. Crashes among older pilots were more likely to occur during the daytime rather than at night and off airport than on airport. The patterns of pilot error in air taxi crashes were similar across age groups. Of the errors identified, 27% were flawed decisions, 26% were inattentiveness, 23% mishandled aircraft kinetics, 15% mishandled wind and/or runway conditions, and 11% were others.
Pilot age is associated with crash circumstances but not with the prevalence and patterns of pilot error in air taxi crashes. Lack of age-related differences in pilot error may be attributable to the "safe worker effect."
飞行员失误与飞行操作类型和基本天气状况之间的关联已有充分记录。而飞行员特征与失误之间的相关性则不太明确。本研究旨在探讨飞行员年龄是否与空中出租车坠毁事故中飞行员失误的发生率及模式有关。
回顾了美国国家运输安全委员会1983年至2002年间涉及非定期第135部运营(即空中出租车)坠毁事故的调查报告,以确定飞行员失误及其他促成因素。使用卡方检验分析了坠机情况以及飞行员失误的存在与否和类型与飞行员年龄的关系。
在研究的1751起空中出租车坠毁事故中,28%是由机械故障导致的,25%是由着陆或起飞时失去控制导致的,7%是由目视飞行规则条件进入仪表气象条件导致的,7%是由燃油耗尽导致的,5%是由滑行导致的,28%是由其他原因导致的。年长飞行员的坠毁事故更有可能发生在白天而非夜间,且发生在机场外而非机场内。各年龄组空中出租车坠毁事故中飞行员失误的模式相似。在已识别的失误中,27%是错误决策,26%是注意力不集中,23%是对飞机动力学处理不当,15%是对风和/或跑道条件处理不当,11%是其他失误。
飞行员年龄与坠机情况有关,但与空中出租车坠毁事故中飞行员失误的发生率及模式无关。飞行员失误中缺乏与年龄相关的差异可能归因于“安全工作者效应”。
