Disruption of global synchronization and navigation: Global navigation satellite systems (things like GPS) could be disrupted for several days. This would be annoying for navigation in general, but more importantly, we also use it for global synchronization for all kinds of things, like our financial system. This would not be possible during the storm.
I thought some satellites would get their cumulative dose in a bad solar storm, so then they would be permanently damaged (though that might just be with EMP particles).
Aviation problems: Airplanes might be exposed to higher radiation doses than normal. This would not have any immediate effects, but would condemn a random collection of people on the airplanes to cancer later in their life.
With the satellites I understood it as they being disrupted in several ways:
Their signal gets garbled, but they remain fine
Their electronics get fried
The increased drag in the atmosphere leads to them being de-orbited
What ultimately happens depends a lot on the orbit and how hardened the satellite is, but I havenāt seen research that tries to assess this in detail (but also havenāt looked very hard for this particular thing).
About the airplanes: Yeah this might be an option, though I think the paper that mentioned this said something along the lines āit is quite hard to predict where in the airplanes path the radiation will increase and they can receive the radiation quickly, which makes this hard to avoidā.

Have they thought about flying lower in an event?
