由于A320机型需立即进行软件修复的指令，全球航班在出行高峰期陷入混乱。
10月30日捷蓝航空的一起事件触发了欧洲航空安全局的紧急行动。
A320系列飞机是全球范围内应用最广泛的商用客机之一。
周五，空中客车公司下令对6000架A320系列飞机立即进行软件修复，此举影响了全球半数以上的窄体客机机队，并迫使航空公司在一年中最繁忙的旅行周末之一停飞部分飞机，导致全球部分航空网络陷入混乱。
欧盟航空安全局在一份指令中表示，捷蓝航空（JetBlue）10月30日的一架航班遭遇了"非指令性有限俯冲事件"。美国联邦航空管理局周五也发布紧急指令，要求相关机型运营商解决这一故障。
这一混乱迅速波及美国的假日出行，并延伸至澳大利亚。空客公司表示，之所以发布这一指令，是因为"近期一起涉及A320系列飞机的事件表明，强烈的太阳辐射可能会损坏对飞行控制功能至关重要的数据。"
监管机构警告称，在最坏情况下，该问题可能导致电梯出现“非指令性移动”情况。
全球最大的A320运营商美国航空公司向CNBC表示，此次空客召回事件影响了其209架飞机，较最初确定的340余架有所减少。
美国航空公司表示：“截至美国中部时间下午6点，美航尚有不到150架飞机待升级。”
我们预计绝大部分工作将于今日至夜间完成，仅剩少量任务需留待明日收尾。
美国联合航空公司表示，其机队中有六架飞机受到影响，预计将导致"少量航班出现轻微延误"。
新加坡航空部分持股的印度航空公司表示，已完成逾40%受影响飞机的软件更新，目前没有航班取消，但部分航班出现延误或改期。
新加坡航空集团旗下另一家航空公司酷航表示，其29架空客A320飞机中有21架需要进行维修，并计划于本周六前完成相关工作。
澳大利亚捷星航空在发现部分飞机需进行软件升级后，取消了约90个航班。这家廉价航空公司及其母公司——澳大利亚国家航空公司澳洲航空(Qantas)共同占据国内市场份额的65%，而竞争对手维珍澳大利亚航空的市场份额为33%。
据路透社报道，日本全日空控股集团（ANA Holdings）周六取消了65个航班。该航空公司及其旗下子公司（如乐桃航空）运营着日本规模最大的空客窄体机队，而其竞争对手日本航空公司则主要依赖波音飞机。
这项指令在空客55年历史上规模位居前列，对亚洲地区的冲击尤为严重——该地区短途航线网络主要依赖单通道的A320系列机型。
An order for an immediate software fix for the A320 disrupted flights worldwide during a peak travel period.
A JetBlue incident on Oct. 30 triggered EASAs emergency action.
Parts of the world's air travel network were disrupted Friday after Airbus ordered immediate software fixes for 6,000 A320-series aircraft, a move that affected more than half of the narrow-body fleet and forced airlines to ground jets during one of the busiest travel weekends of the year.
The European Union Aviation Safety Agency said in a directive that a JetBlue flight on Oct. 30 experienced an "uncommanded and limited pitch down event." The U.S. Federal Aviation Administration also issued an emergency directive Friday ordering operators of the affected model to address the glitch.
The disruption quickly spilled into U.S. holiday travel and stretched to Australia. Airbus said it issued the order after "a recent event involving an A320 Family aircraft has revealed that intense solar radiation may corrupt data critical to the functioning of flight controls."
Regulators warned that the issue could lead to "an uncommanded elevator movement" in the worst-case scenario.
American Airlines , the world's largest A320 operator, told CNBC that the Airbus recall impacted 209 aircraft, down from the more than 340 initially identified.
"As of 6 p.m. CT, American has fewer than 150 aircraft remaining to update," American Airlines said.
"We expect the overwhelming majority of those to be completed today and through the night, with only a handful remaining for completion tomorrow."
United Airlines said six aircraft in its fleet were affected, and the carrier expected "minor disruption to a few flights."
Air India, which is partially owned by Singapore Airlines , said it had completed software updates on over 40% of its affected aircraft and that there were no flight cancellations, although some flights were delayed or rescheduled.
Scoot, another carrier under the Singapore Airlines group, said 21 of its 29 A320s required the fix and that it aimed to complete the work by Saturday.
In Australia, Jetstar Airways canceled around 90 flights after identifying aircraft that required the software correction. The budget airline and its parent company, Qantas, which is Australia's national flag carrier, together hold about 65% of the domestic market , while rival Virgin Australia has a 33% share.
Japan's ANA Holdings canceled 65 flights Saturday, Reuters reported. The carrier, along with affiliates such as Peach Aviation, operates the country's largest Airbus narrow-body fleet, while rival Japan Airlines relies mostly on Boeing aircraft.
The directive among the largest in the 55-year history of Airbus hit especially hard in Asia, where the single-aisle A320 family anchors short-haul networks.
