Would a powerful solar storm knock out electronics in planes?

A storm as powerful as the Carrington event of 1859 might cause some issues, says a reader, but modern planes have a lot of safeguards built in. You should be more worried about "superflares"

This C2 image was turned 90 degrees so that the blast seems to be pointing down. A second image, from the EIT disk imager on a different day was enlarged and superimposed on the C2 image so that it filled the occulting disk for effect. CREDIT ESA/NASA/Soho

The sun emits solar wind and occasional solar flares, followed by coronal mass ejections (CMEs), which release clouds of up to a billion tonnes of charged particles into space. While most CMEs miss Earth, those coming our way typically take one to five days to reach us. Our magnetosphere deflects most of the particles, and the atmosphere protects us from ionising radiation, but CMEs can cause…
