This is a very peculiar request. From time to time, my wifi resets which usually represents a loss of comms for a bout 30 seconds. That means that the navigraph setup goes blank (pinned charts, for example).
The only way to “recover” the setup is to unload the flight and reload the flight. I mean, it’s not a huge deal, for sure, but if there was a simple refresh button, that would be great.
Obviously, best solution was for the whole thing not go go blank. But, I take what you can give me
