Airbus has warned that global flights may face disruption.
Consequently, the company ordered urgent modifications to many A320-family aircraft.
The problem occurs because solar radiation can corrupt data in flight-control computers.
Airbus Orders Urgent Modifications
Previously, a JetBlue aircraft suddenly lost altitude in October, revealing the issue.
Investigators believe intense solar activity damaged the elevation-control computer.
Around 6,000 Airbus aircraft need updates worldwide.
Fortunately, most require only a simple software patch.
However, older models may need hardware changes.
Meanwhile, the situation affects a major US holiday weekend.
American, Delta, JetBlue and United operate many A320 jets.
Limited Impact Elsewhere
So far, disruption in the UK remains limited.

However, some airlines abroad have already cancelled flights.
Nigeria is monitoring the situation carefully.
Moreover, one stakeholder fears older Airbus models may face grounding.
Current fleet data shows Ibom Air operates most Airbus aircraft in Nigeria.
Its A220-300 aircraft do not belong to the affected group.
Other Nigerian airlines mainly operate Boeing and regional jets.
Solar Radiation Risks
Airbus has addressed radiation risks in newer fly-by-wire models before.
Therefore, the A220 does not appear affected unless authorities advise otherwise.
Expert Ian Getley explains how solar eruptions pose risks.
Coronal mass ejections release highly charged particles from the Sun.
These particles can disrupt aircraft systems above 28,000 feet.
Interestingly, Getley began his research after experiencing interference in 2003.
