美国联邦航空管理局（FAA）近日颁布一项飞行操作指令，要求航空公司针对波音（Boeing）737系列客机飞行中驾驶舱或客舱出现异常高温情况的报告制定明确处置流程。该指令要求飞行员在遭遇此类事件时，需立即执行特定检查程序并采取应急降温措施。
根据文件要求，航空运营商必须在规定期限内修订飞行手册，增加对高温事件的识别与响应程序。此举旨在通过标准化操作流程，降低因舱内温度骤升可能导致的安全风险。目前已有包括西南航空（Southwest Airlines）在内的多家运营商开始推进相关培训。
业内专家指出，此次指令反映出监管机构对客机环境控制系统潜在问题的关注升级。尽管当前未造成重大事故，但预防性措施的强化将有效提升航空安全冗余度。
