Airlines work to fix software glitch on A320 aircraft and some flights are disrupted

"Airlines around the world canceled and delayed flights heading into the weekend to fix software on a widely used commercial aircraft after an analysis found the computer code may have contributed to a sudden drop in the altitude of a JetBlue plane last month. Airbus said Friday that an examination of the JetBlue incident revealed that intense solar radiation may corrupt data critical to the functioning of flight controls on the A320 family of aircraft."

"The problem was introduced by a software update to the plane's onboard computers, according to the agency. In Japan, All Nippon Airways, which operates more than 30 planes, canceled 65 domestic flights for Saturday. Additional cancellations on Sunday were possible, it said. The software change comes as U.S. passengers were beginning to head home from the Thanksgiving holiday, which is the busiest travel time in the country. American Airlines has about 480 planes from the A320 family, of which 209 are affected."

An analysis found computer code may have contributed to a sudden altitude drop of a JetBlue plane, prompting airlines worldwide to cancel or delay A320-family flights to install a software fix. Airbus determined intense solar radiation may corrupt data critical to flight-control functioning. The FAA and the European Union Aviation Safety Agency required carriers to apply a new software update, affecting more than 500 U.S.-registered aircraft. All Nippon Airways canceled dozens of domestic flights; American Airlines said 209 of its roughly 480 A320-family planes were affected and anticipated some delays. The reset typically takes about two hours, with most updates expected quickly.
