Airbus's mandatory software update has affected 6,000 A320 family aircraft worldwide. While airlines emphasize that the error does not directly impact passenger safety, they continue to manage flight operations in a controlled manner. In Turkey, Turkish Airlines and AJet have temporarily grounded a total of 15 Airbus aircraft as part of the update. Pegasus, which has 46 A320s in its fleet, stated that the necessary technical process is being managed with schedule adjustments.
The mandatory software update mandated by Airbus has affected 6,000 A320 family aircraft worldwide, leading to widespread planning changes in the aviation sector. While airlines emphasized that the issue does not directly jeopardize passenger safety, they stated that operations are being conducted meticulously.
In Turkey, THY and AJet temporarily grounded a total of 15 Airbus aircraft. Pegasus, which has 46 A320s in its fleet, reported that they are managing the process through schedule adjustments.
RISK OF DATA CORRUPTION
According to Airbus, a flaw detected in the flight control system software used in the A320 family can lead to data corruption in the flight computer, especially under extraordinary atmospheric conditions such as intense solar flares.
Due to this situation posing a controllable but "known technical risk," Airbus urgently initiated an update process in collaboration with national aviation authorities and EASA.
Airbus stated that this is the largest software intervention in the company's history due to the scale of the issue.
DELAYS AND FLIGHT ADJUSTMENTS WORLDWIDE
Due to the mandatory update, many airlines had to take A320 family aircraft for 2–3 hours of maintenance and software installation before departure. In this context, worldwide:
American Airlines initially included 340 of the more than 480 A320s in its fleet on the update list; as the process progressed, the number dropped to 209.
In India, IndiGo, Air India, and Air India Express began software installation on a total of 338 aircraft; some flights experienced delays of 60–90 minutes.
Intense scheduling, especially coinciding with holiday return traffic in the U.S., increased operational pressure on airlines.
SITUATION IN TURKEY: LIMITED IMPACT ON FLIGHTS
THY and AJet temporarily grounded a total of 15 affected aircraft by pulling them into planned maintenance intervals. During this process, there were aircraft changes on some routes, short delays, and minor adjustments in flight planning.
Pegasus stated that they are closely monitoring the process for their A320 family aircraft with their technical teams and managing the necessary updates through schedule optimization and rotation adjustments.
EMPHASIS ON "NO FLIGHT SAFETY RISK"
Airbus and airlines emphasize that the detected software flaw does not directly threaten flight safety.
It was stated that the update is being made to eliminate a foreseeable technical risk and that the aircraft continue their operations safely.
