英国空中交通管制服务提供商NATS公布了9月8日一起技术故障的初步调查结果1。该事件由国家航空系统（NAS）中一小段代码的软件缺陷引起1，导致飞行数据更新受损，NATS随后对英国全境实施交通管制限制，持续约6小时1。虽然同日晚间运营恢复正常，但清除积压航班耗时超过两天，数十万乘客的出行计划因此中断1。
NATS首席执行官Martin Rolfe表示，"这是我们飞行数据系统特定部分的软件问题，我们已追踪到一小段编码"1，并强调"在任何时候安全都没有受到质疑"1。根据报告，故障发生于毫秒级时间内，起因是飞行代码请求处理中断后未能正确恢复，导致输出数据损坏1。该事件主要影响伦敦区域管制中心处理的高度24,500英尺以上的飞行1。
此次事件与2023年8月发生的大规模系统中断无关，亦非军事干预所致1。NATS表示过去10年已投资超过10亿英镑用于系统建设，并计划于2033年底前再投资10亿英镑1。
The UK's National Air Traffic Services (NATS) has published its preliminary findings into a software defect that disrupted air traffic control across Britain on September 8. 1 The incident stemmed from a coding flaw in the National Airspace System (NAS) that corrupted flight data updates, forcing NATS to impose traffic management restrictions nationwide for approximately six hours. 1 Although normal operations resumed later that evening, the backlog of delayed flights took more than two days to clear, affecting hundreds of thousands of passengers. 1
CEO Martin Rolfe attributed the failure to a specific software problem within the flight data system, stating: "This is a software issue in a particular part of our flight data system, and we have tracked it to a small piece of coding." 1 He emphasized that "safety was never questioned at any time" during the incident. 1 The defect occurred when a flight code request processing routine failed to recover properly, generating corrupted output data within milliseconds, with the primary impact on the London Area Control Centre affecting flights above 24,500 feet. 1 NATS clarified that the incident was unrelated to the major system outage in August 2023 and was not caused by military intervention. 1
NATS noted its substantial capital investment in infrastructure, having spent over one billion pounds in the past decade and planning an additional one billion pounds investment by the end of 2033. 1
