FS2004 crashes when zooming out on GPS

[TheRedBadger]

I thought this error may have had to do with the computer's performance (it may still be that), but I did specifically pinpoint the last chain of the crash to be when zooming out on the GPS to 150nm. I also noticed FSrealWX had stopped working when the sim crashes, although the issue was replicated without it active.

 

Crashes occur at the airports tested with or without an IFR flight plan. Oddly enough, I was able to fly 3R3-RWV yesterday just fine (old Austin Executive Airpark). Maybe I didn't zoom out all the way, by luck? (verified; still crashed. It's a short route so I likely didn't ever zoom out that far).

 

Tried different flight plans (DFW-JAX, DFW-AUS, DFW-ORD, high-altitude routes on all). Attempted a direct route DFW-ORD, all crash.

 

Tried same DFW-JAX route, high-altitude on the default Cessna, crash observed.

 

Tried different origin point, AUS-ORD, still crashes.

 

Tried SEA-ORD, no crash observed.

Tried SFO-LAX, no crash observed.

Tried MEM-DFW, crash observed.

 

I'm noticing when spawning in airports in the central time-zone they crash.

 

Tried ATL-DFW, crash observed.

 

Ok so that didn't prove my point.

 

Tried SAN-SEA, no crash observed.

Tried DEN-PHX, no crash observed.

Tried SLC-ELP, no crash observed.

 

Pacific and Mountain time zone airport origins do not crash the simulator.

 

Tried DTW-CLE, no crash observed.

 

....

 

Tried CLE-BNA, no crash observed.

Tried BNA-FLL, crash observed.

Tried DAL-ORD, crash observed.

 

Whether or not addon scenery was installed did not make a difference.

 

Attempting DFW-JAX after having spawned in SLC for the route crashed the sim immediately upon spawning (GPS was at 200nm).

 

So it seems certain origin airports regardless of aircraft crash the simulator when zooming out, sometimes high-altitude, sometimes direct. It cannot be precisely singled out, but it does have something to do with the simulator.

This could be a corrupt fs9gps.dll in the Modules folder - sometimes a panel or aircraft comes with the FSX version which is also named fs9gps.dll. If you have a backup, from a few months ago just to be safe, try replacing the fs9gps.dll module.

Another possibility is a corrupt magdec.bgl file. Have you replaced that at some point with an addon version?

Sorry for the delay... I actually ended up just reinstalling FS9 which of course worked. I appreciate the help though as this may be the solution to future mishaps. Thanks y'all!
