Airbus A320 – intense solar radiation may corrupt data critical for flight (airbus.com)

Article summary

Airbus A320 aircraft have been grounded due to a potential issue with intense solar radiation corrupting critical flight data. The problem was discovered after an incident on a JetBlue flight, where the plane experienced a sudden drop in altitude and made an emergency landing. At least 15 passengers were injured in the incident. The cause of the issue is believed to be related to solar radiation, possibly a Coronal Mass Ejection, affecting the aircraft's electronics.

What commenters say

• The incident may have been caused by a Coronal Mass Ejection, which can disrupt electronic systems, and a similar event had been predicted by NOAA around the same time.
• The problem could be mitigated with a software fix, such as storing multiple copies of critical data and adding checksums, rather than requiring a hardware solution.
• Some commenters believe that the issue highlights the importance of robust programming and error correction in safety-critical systems, citing examples such as the Apollo moon landing.
• Others argue that the root cause of the problem is not the hardware or software, but rather pilot error and inadequate training, pointing to the Air France Flight 447 crash as an example.
• There is a need for more transparency and open-source design in aviation systems to identify and address potential defects and vulnerabilities.
• The use of redundant systems, such as triple-redundant microcontrollers, could help eliminate certain classes of failures and improve overall safety.
• Some commenters disagree on the effectiveness of pilot training and the role of automation in preventing accidents, with some arguing that proper training and procedures can mitigate the risk of human error.
• The incident highlights the complexities and challenges of designing and operating safety-critical systems, and the need for a multi-faceted approach to ensuring reliability and safety.
