Electromagnetic pulses are a staple in sci-fi, and they're basically the writers' hand-waving of "deletes technology" weapons. This question asks about whether or not GA motors would survive such a thing, and the answer seems to be "a big enough EMP will still cook it, but it'll take more to kill the mags than it would the GPS and radio." A far more likely scenario of concern, however, is solar storms.
The Carrington Event was a titanic Coronal Mass Ejection(CME) that damaged telegraph networks, ionized the atmosphere powerfully enough to produce dramatic aurorae, and is viewed as a possible global catastrophe scenario given the broad dependence on large electrical power grids. The event carried on long enough that a 7-line conversation took place between Boston and Portland after both stations had disconnected their power supplies.
Unlike an EMP, which delivers one powerful shock to the system, solar storms produce prolonged periods of induced current in exposed hardware.
Obviously radios and sensitive electronics are hosed, and possible permanently lost. But what are the likely effects on aircraft engines?
Carrington events are legitimate considerations for electrical system planners and disaster management professionals, but I'm wondering if they're of concern for the aviation sector?
For a specific case, The Long Dark's story begins with a De Havilland Beaver becoming uncontrollable due to a Carrington Event (while being operated in hilariously questionable weather, to boot). The DHC-2 comes in radial and turboprop versions, however, so I'm curious if one or the other of these propulsion schema would be preferable to someone concerned about solar storms?
