Thousands of Airbus aircraft around the world were grounded after it was discovered that intense solar radiation could interfere with onboard flight control computers.
According to the BBC, some 6,000 A320 planes were thought to be affected – half the European firm’s global fleet – but it is understood most will be able to fly again after undergoing a quick software update.
It is understood that on around 5,100 Airbus planes, the issue can be addressed using a relatively simple software update which would typically take about three hours.
However, the remaining 900 aircraft, which are older versions, will need to have onboard computers physically replaced, and will not be allowed to carry passengers again until the job has been completed.
As well as the A320, the company’s best-selling aircraft, the vulnerability also impacts the A318, A319 and the A321 models.
