美国联邦航空局 （FAA） 报告称，空中交通管制员管理双重角色是导致华盛顿特区机场空中相撞的原因。 FAA report suggests air traffic controller managing dual roles contributed to midair collision at D.C. airport.

美国联邦航空局 （FAA） 关于华盛顿罗纳德·里根国家机场空中相撞事件的初步报告显示，一名空中交通管制员同时处理两个角色，这在时间和交通量上并不常见。 The FAA's preliminary report on the midair collision at Washington's Ronald Reagan National Airport reveals that an air traffic controller was handling two roles simultaneously, which is uncommon for the time and traffic volume. 由于塔台有 85% 的人员，管制员管理直升机交通和飞机的起飞/降落指令。 The controller managed both helicopter traffic and takeoff/landing instructions for planes, due to the tower being 85% staffed. 这种“加倍”的做法虽然被允许，但发生得比平时早，引发了对人员配备标准的担忧，并导致了崩溃。 This "doubling up" practice, though allowed, happened earlier than usual, raising concerns about staffing standards and contributing to the crash.
