I noticed today that my instinct wasn’t playing nicely with the app, and found out about their quite serious outage. Glad to hear the inreach isn’t affected, but that’s really another service provider alltogether. Garmin is just fortunate enough to own the billing rights, as far as I know.
I can’t imagine the impact to aviation is too serious, as a typical navigation database is only updated every 28 days, and you always have either the previous and current revisions, or the current and next revision loaded into the onboard database. Even if you’re out of date, using a current chart to verify the accuracy of your loaded routing is perfectly legal, so long as you follow a few other routing rules such as not flying over any gps only fixes. Folks using handheld devices that update via a download may be unable to get some things on their iPads and whatnot, but there’s no real impact to serious navigation usage.
