我们研究了1983-88年间连续发生的167起直升机通勤者和空中出租车坠毁事件中与飞行员生存相关的因素。病死率和多变量Logistic回归模型调整后的优势比是使用美国国家运输安全委员会(NTSB)的数据确定的。在这6年期间，有29名机长在167起直升机通勤和空中出租车坠毁事故中丧生，病死率为17.4%。与飞行员死亡风险增加显著相关的因素是飞机着火[优势比(OR)20.0，95%可信区间(CI)4.6-86.8]，不使用肩带(OR 9.2，95%CI 2.2-37.3)，以及双引擎飞机(OR 4.8，95%CI 1.3-17.4)。此外，我们还提供了有关紧急浮选设备成功和失败的数据。结果表明，通过预防坠机引发的火灾和推广使用肩带，飞行员在直升机坠毁事件中生还的可能性可以大大提高。
We examined factors related to pilot survival in 167 consecutive helicopter commuter and air taxi crashes that occurred during 1983-88. Case fatality rates and adjusted odds ratios from multivariate logistic regression models were determined using data from the National Transportation Safety Board (NTSB). During this 6-year period, 29 pilots-in-command died in 167 helicopter commuter and air taxi crashes, a case fatality rate of 17.4%. Factors significantly associated with increased risk of pilot fatality were aircraft fire [odds ratio (OR) 20.0, 95% confidence interval (CI) 4.6-86.8], not using shoulder harnesses (OR 9.2, 95% CI 2.2-37.3), and aircraft with two engines (OR 4.8, 95% CI 1.3-17.4). In addition, we present data regarding success and failure of emergency flotation devices. The results suggest that the likelihood of pilot survival in helicopter crashes could be greatly improved by preventing crash associated fires and promoting the usage of shoulder restraints.
