Not quite. The onus is on the pilots to never fly with out-of-date navigation information (it's actually illegal), so if they can't get that from Garmin, they'd just have to get it from somewhere else instead. Garmin's data services being unavailable isn't endangering anyone.

Yep, Plenty of planes flying out there without any electronic maps.

The attack happened about a week after the FAA’s last update went into force. And I believe they’re distributed a week before that.

So the only groundings would’ve been those that have been parked for a while (I guess. I don’t know how they do updates).
