Just out of curiosity...

How exactly do the controllers see where our aircraft are located? Is it by simply reading the lat/long coordinates exported (in my case) by FSX?

The reason I ask is because I've just recently become aware of how erroneous some of the airfield locations in FSX really are. For example, I was planning a flight from St. George, a small Class E in southwestern Utah just inside the PE coverage areas. Loaded up the sim, fired up the Flight1 GTN to lay in a plan through one of the Grand Canyon SFRA corridors, and discovered that the GTN, which reads my position straight from the lat/long reported by FSX, shows me being some 5.5 nm from St. George's real-world coordinates!

Which got me thinking, what would the controllers see if I attempted to start a flight from KSGU, then? Would they see me out in the boonies 5 miles northwest of where they see the airfield?

Yes, your sim is apparently still using the OLD KSGU Airport (details here).

The lat/lon of your aircraft is sent to the server. That's what sent to the controllers' scopes.

Ahh! Apparently I just had the dumb luck to jump into an airport which has moved since FSX was released, and didn't realize it.

Which is good, in a way. For a while there, I was really concerned about progressive massive error's in FSX's database.

If you like SGU - here are some links to the new airport scenery: FSX /// XPlane 10

It will be under KDXZ however all your updated nav database will work for the updated airport
