Globally, flights faced delays and cancellations following Airbus’s directive to implement fixes on 6,000 of its A320 series aircraft, as reported by The Guardian.

The firm stated that it is taking measures because “examination of a recent incident involving an A320 Family aircraft has indicated that high levels of solar radiation could disrupt data essential for the operation of flight controls.”

According to industry insiders, Reuters notes that the incident referenced was a JetBlue flight on October 30th from Cancun, Mexico to Newark, New Jersey, where the aircraft unexpectedly lost altitude and was compelled to execute an emergency landing in Tampa.

The Federal Aviation Administration has allegedly released an emergency airworthiness directive mandating that the affected aircraft revert to earlier software versions before resuming flights. Airbus mentioned that a smaller group will require hardware modifications.
