Greetings,
I'm setting up a new computer, and I'm trying to get the program to open up with my home area centered on the map. I'm in east TN, but it shows me in northeast Atlanta. I somehow managed to set this on my old computer, but I can't figure out how I did it. The settings all look the same except for GPS.
On my old computer, I have a flashing red "No GPS Position Lock" on the screen all the time. If I go to Menu/About/Connected devices, it says Auto-Detect (not detected). On the new computer, I get the same no GPS lock message for a few seconds, then changes to a grey flashing "Weak GPS Signal". Connected devices on the new computer says NMEA Output Controller, then lists NMEA commands it's sending to COM1-9600. I clicked the Select Wireless Device button, and selected Auto-Detect, but it doesn't change the behavior.
I use AT&T wireless for internet, and when I use Ookla speed test, it shows my closest server as Alpharetta GA, which happens to match what iFly is showing on the map, so that must be where the location is coming from. That isn't any different on the old computer, so somehow I must have been able to override that on the iFly app.
Is there a way to chose your default location, and disable any GPS attempt?
Thanks,
Rusty

If you don't have a GPS signal (like I don't on my desktop PC), then you do always get that flashing No GPS Signal warning -- which though it can be "disabled", keeps coming back (5 minute timer?).
How you set your location if there's no GPS signal to override it, is to go into the Flight Plan screen and enter (or load) a flight plan that starts at the location you want your aircraft to be on the map. In fact, the flight plan can be just one waypoint (the location you want). That is, when I want my aircraft to show up at Arlington Airport (KAWO), I can just enter a flight plan consisting of only KAWO.
Once your FP is entered, close the Flight Plan screen, which returns you to the map and your aircraft will be where you want. Then go back to the Flight Plan screen and clear the FP (if you want), and close it again. If you enter the FP, then clear it before you close the Flight Plan screen, this doesn't work. You have to close the Flight Plan screen with an active FP in it.

Thanks for the info. I remembered that it had something to do with the flight plan, and it was the first thing I tried. I leave that default single waypoint plan on the old computer, but doing that on the new computer doesn't change my location on the screen.
The key is almost certainly the GPS. For some reason, the new desktop machine is showing a single bar of signal for the GPS, and giving me the weak GPS warning. The machine certainly has no GPS, and if it did, it wouldn't be showing me in Atlanta. Somehow it's getting my position as a fake GPS signal from the 4G internet service. I haven't found any way to tell the program not to use this fake signal.
I just disconnected the internet cable and was able to use the flight plan trick to change my location. During that time, the GPS had no signal. As soon as I plugged in the ethernet cable, the single bar signal came back, and my location went back to Atlanta. I'll have to try to figure out how this fake location is being generated, and try to stop it. Any ideas?
Thanks,
Rusty

This is not exactly true. iFly can get location information (at least) three different ways: via external GPS (like from an ADSB receiver), via the internal GPS of the device it's running on (like the 720, 740, or an Android tablet or iPhone), or it can get an approximate location from IP address location determination if the device is connected to the internet. The "Weak GPS Signal" message can mean either that it's having trouble tracking a sufficient number of GPS satellites, or that it is using the internet-based approximate location technique.
I'm not sure if iFly actually knows the source of the location information it's getting, or if the OS just provides location data and some kind of quality indicator so the app has an idea of how (in)accurate the location data is.
In another thread, Brolin gave instructions for how to force iFly to use the internal device GPS instead of preferring an external device (though I don't remember where that setting is and can't find Brolin's post right now), but I do not know how (or if) you can tell iFly to turn off *all* location tracking.

Try this: In the Windows search field (usually in the lower-left corner of the screen, next to the Start menu icon), type "location". The top search result should be "Location Privacy Settings", and if you go there, you can change settings about whether Windows will try to detect your location, and if it can, whether it will pass that location information down to apps. There is also an option to establish a "default location" for the device to pass to apps if Windows is unable to dynamically determine a location.
You can probably adjust these settings appropriately to get iFly to behave the way you want (perhaps you could compare these settings between your old and new computers). It may also result in other changes that may or may not be what you want (Store websites that automatically try to determine the store closest to you, Google maps default start point, etc.)
