On Saturday, airlines around the world scrambled to fix software issues on hundreds of Airbus A320s after a JetBlue flight's sudden altitude drop revealed a glitch linked to solar radiation.
There were short-term disruptions at several airports as US passengers prepared to return home after the Thanksgiving holiday, one of the busiest travel times in the country, News.Az reports citing foreign media.
Airlines around the world reported short-term disruptions heading into the weekend as they fixed 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 FAA joined the European Union Aviation Safety Agency in requiring airlines to address the issue with a new software update. More than 500 US-registered aircraft will be impacted.
The EU safety agency said it may cause “short-term disruption” to flight schedules. 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 US 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. The fix should take about two hours for many aircraft and updates should be completed for the overwhelming majority on Friday, the airline said. A handful will be finished Saturday.
American expected some delays but it said it was focused on limiting cancellations. It said safety would be its overriding priority.
