Solar Radiation Issue Resolved: Airbus Flights Back to Normal

New York, USA — December 1, 2025: With thousands of international students from India getting ready for the U.S. tax season, it is critical to comply with the tax laws as an international F1 or J1 visa student. U.S. tax laws can be complicated. The right approach to the tax filing system minimizes the chances of making mistakes and incurring penalties. With so many people filing taxes in the USA, it is necessary to know the tax laws because the student is only in the country for a short period of time, most likely less than 5 years.

Every international student should know basic tax forms, exemptions, and requirements according to the IRS and every university’s tax liability guidelines across the United States. Tax obligations remain whether you are working part-time on campus, receive a stipend, or have zero income. Make sure to know what forms to send and what deadlines to observe.

The Immediate Impact on Airlines Worldwide

The warning from Airbus led to swift action by airlines globally, with affected aircraft grounded temporarily until the issue could be addressed. As of Saturday, December 1, the majority of the affected planes had been updated with new software, allowing them to return to normal operations. However, a small number of older planes still require new computer replacements and remain grounded.

French Transport Minister Philippe Tabarot confirmed that the software updates had gone smoothly for more than 5,000 aircraft, with fewer than 100 planes still needing attention. Airbus CEO Guillaume Faury acknowledged the logistical challenges and delays caused by the issue but reassured passengers and airlines that teams were working quickly to complete the updates.

Disruptions at Major Airports

The disruption caused by the Airbus grounding was most acutely felt at airports with high volumes of flights operated by Airbus aircraft. In Paris, where many of the affected planes were stationed, Charles de Gaulle Airport experienced delays and cancellations, particularly among Air France flights. The airline worked rapidly to carry out the necessary software updates, though a number of flights were delayed.

American Airlines also reported that its operations would be impacted, but it expected the majority of updates to be completed by Saturday. Delta Airlines stated that it believed the impact on its operations would be minimal.

The UK Civil Aviation Authority confirmed that British airlines had been working overnight to complete updates, minimizing any major disruptions. London Gatwick Airport reported some disruptions, while Heathrow saw no cancellations. Manchester Airport and Luton Airport in the UK also reported no significant impact.

EasyJet announced that it had completed updates on a significant number of its aircraft and was planning to operate as normal. Similarly, Wizz Air completed the necessary software updates and returned to full operations.

In Australia, Jetstar was one of the hardest-hit airlines, canceling 90 flights due to the grounding of its Airbus planes. Although most of its aircraft have since been updated, some delays were expected to continue through the weekend. Air New Zealand, which also operates Airbus A320 aircraft, temporarily grounded its planes but resumed service after completing the necessary updates.

The Underlying Cause: Solar Radiation and Aircraft Safety

The root cause of the issue was traced back to a JetBlue Airways flight from the United States to Mexico, which had to make an emergency landing after suddenly losing altitude. The incident prompted an investigation by Airbus, which found that solar radiation, released periodically by the Sun, could interfere with the aircraft’s onboard computing systems. At high altitudes, this radiation could corrupt crucial data used to calculate the plane’s elevation, leading to potential inaccuracy in flight controls.

This issue affected several models of Airbus aircraft, including the A320, A318, A319, and A321, all of which are part of Airbus’s popular narrow-body aircraft family. The vast majority of the fleet was able to undergo a software update, but older models still require a full replacement of their computing systems. The process of replacing these systems will vary depending on the availability of replacement computers, and older planes are expected to remain grounded until the new systems are installed.

Airbus’s Response and Ongoing Efforts

While the software updates have been implemented quickly for the majority of affected aircraft, Airbus CEO Guillaume Faury issued an apology for the “logistical challenges and delays” caused by the situation. The company worked closely with airlines to minimize disruption, especially for long-haul flights where Airbus planes are often used.

Faury assured the public that Airbus was continuing to monitor the situation and ensure that all planes affected by the issue are properly updated. With fewer than 100 planes still needing updates as of the latest report, Airbus has made significant progress in resolving the problem.

The issue of solar radiation and its impact on aviation safety is a reminder of the challenges modern airlines face in ensuring the safety and reliability of aircraft systems. With increasing reliance on technology and onboard computing systems, ensuring that these systems are protected from external factors such as solar radiation will remain a key focus for aerospace manufacturers like Airbus.

Looking Ahead: Impact on the Industry

All eyes in the business world are set on Airbus as it resolves the final issues with its planes. Most of the affected flights are back to normal, but the replacement of outdated aircraft systems across the global fleet still shows the challenges in maintaining world-wide aircraft fleets. The global airline industry must learn to continue to adapt to the changes in tech.

For the travelers impacted by the recent changes in schedules, it goes to show just how quickly the industry moves, but more importantly it shows just how valuable up to date information is when flying.
