Declarations, pilot/glider details and settings are
saved in a .txt file, easily edited with Notepad or
similar program.

The manual says the RJ45 socket and lead is wired for
external power, pilot event and NMEA out. The only
way to input data would be through the USB lead.

The assumption is that you'll have access to a computer
at your airfield, which is a bit tough on those of
you flying from a dirtstrip in the middle of nowhere
and no laptop.

If you don't have cockpit storage space and don't trust
velcro, tape it to your shoulder strap, battery mount,
wherever. Or make your own mount.
