That's interesting. Not sure if it's a "jurisdiction" thing, as in if it's a part of the airplane, they go into the certification regime?

For instance, laptop PCs running Windows and iPads are certified for EFB use now (I would assume for approach plates as well), but I'm not sure what the limitations are, or what certification level that is.

Btw, what did you work on in avionics, and what made you move to a different area of work?
