(Wild guess here, the line of PAX seems to be roughly pointing the 0,0 latitude point in the Atlantic, maybe that's a clue what's going on?)
This happens because GSX hasn't got the location of Jetways from Simconnect yet, so they are initialized at a default 0,0 location. This can happen for a variety of reasons:
- The scenery has lots of jetways, so the data about them hasn't arrived entirely when you called GSX. In this case, you only need to wait a bit more after loading an airport, not call GSX immediately, wait a few seconds. Don't take this literally, it takes a 3-5 seconds at KORD (the airport with most jetways in the world), but on my system, and with not many other add-ons installed so, it might be more.
- At least one jetways has a problem. There's a bug/quirk/issue in the new Jetway API that, if even one jetway has a problem, like a missing Simobject, the call to get all of them fails completely, so we don't get any data on any jetway. We reported this to Asobo while in Beta, asking to get at least a list of the working ones, but it hasn't been fixed. Because of this, GSX has a backup strategy that, when this error is reported, it will go in "slow mode", asking for each jetway individually, parking by parking, which is way slower.
- Sometimes, even if there's no problem with the scenery jetways themselves, it's possible the problem has been caused by Simconnect being too overloaded by other add-ons, most likely AI Traffic products that inject too many AI, exceeding the maximum number of objects in the simulation, which results GSX just not getting the data it needs from the simulator, because Simconnect communication became erratic. This will ALSO cause failing to get data about jetways, so all of them will be in the (wrong) default location.
