If the latter was true, then "wheelWeightState" (and others) would not work. But, they do work.

Not necessarily. All this could be reported up to airline HQ through the satellite link and then the IFE/customer WiFi could be downloading it again to serve locally.

That would prevent any need for direct connection between the systems.

Is that how it works? I doubt it. But it could be done.

The weight-on-wheels switch reports its in-the-air status over ADSB. It errs in the direction of assuming in-the-air, which was implicated in a near miss on the ground in 2020 between two Air Canada flights[1][2]
