6000架飞机要召回？空客回应：只需本地软件调整即可

Core Viewpoint - The European Union Aviation Safety Agency (EASA) issued an emergency airworthiness directive requiring the immediate grounding of all affected Airbus A320 aircraft due to concerns over flight control software vulnerability to strong solar radiation [1][4]. Summary by Sections Emergency Airworthiness Directive - EASA's directive was prompted by Airbus reporting that a significant number of A320 series aircraft were affected by flight control software that could be compromised by intense solar radiation, necessitating urgent grounding and implementation of existing software and/or hardware protective measures to ensure fleet safety [1][4]. Technical Assessment and Background - A recent incident involving a JetBlue A320-200 aircraft, which experienced an uncommanded and limited dive, raised alarms. The automatic pilot remained engaged during the event, leading to a brief altitude loss before normal flight resumed. Initial technical assessments by Airbus indicated that a fault in the Elevator and Aileron Control (ELAC) system could be a contributing factor [4][6]. - Airbus confirmed that the A320 aircraft requires urgent replacement of a flight control software susceptible to solar radiation, which could damage critical data necessary for flight control. Airbus proactively contacted aviation authorities to implement preventive measures [4][6]. Impact on Airlines - Reports suggested that Airbus would recall over 6,000 A320 aircraft globally. However, Airbus China clarified that this statement was inaccurate, as the software update could be performed locally without sending the aircraft back to Airbus headquarters in France [1][6]. - As of the end of November 2025, China has a total of 2,015 A320 aircraft, representing 48.3% of the total civil aviation fleet, distributed among 24 airlines [6][7]. - Industry experts indicated that while there would be some impact on operations, the majority of aircraft could resolve the issue through software updates, with minimal aircraft requiring software replacement. The software upgrade process is estimated to take about two hours [7].
