Ok so just to be clear this isn’t the first time a gps time rollover has occurred. The only real difference between this time and last time is that god technology is widely deployed at the consumer level.
As for the risk to flights:
* this has happened before, and I don’t recall any plane accidents then
* I assume pilots would notice if they’re suddenly substantially off course - it’s not a gradual drifting change, it’s a big kachunk change if software isn’t handling it correctly.
* there are many other (non-gps) signals including radio that are used to track where an aircraft is.
If anything I’d be more concerned about drivers getting lost in their cars
