I have one of these $2000 SD cards in my Diamond DA40. It lets me connect my iPad to my aircraft so I can transfer updated databases, flight plans, and see real time avionics data. It's pretty cool. https://www.garmin.com/en-US/p/155337/
Damnnnnn that's cool but ouch. I know you're really buying the whole platform and capability and flight-worthy certification but $2K for what is basically a wifi dongle still makes my head spin.
General aviation is for billionaires with how expensive it is.
It’s sad as a regular person that I could never be able to afford to fly. Even in a 75 year old piece of garbage with a carburetor
