In case of a temporary network outage MSFS mostly degrades gracefully, and the missing functionality does not prevent completing the flight (e.g., offline scenery is still available, offline ATC voices still work, and so on).
But Navigraph charts are completely gone with an outage, and completing the flight without approach charts can be very inconvenient.
Is there a workaround for that, other than the tedious task of printing all necessary charts to .pdf in case there is a network outage during any particular flight? E.g., could charts on the currently open pinboard be made to remain available, obviously without moving map functionality, if Navigraph drops offline during a flight?
