JRBarrett, Thank you very much. That did it.
Thanks every one. I've been considering learning to fly for some time now. So I'm starting to take FSX Seriously, but that's another topic.
I setup a default Cessna 172SP to be parked at Ramp 12 at North Las Vegas. I set it as my default flight. However after 1-2 minutes of just sitting there. The engine dies. I'm getting an Oil Pressure warning before death. This only happens when I'm idling. When it's in motion it's fine. I'm hesitant to take her into the skies to see what's going on. I'm also running with real weather (downloaded every 15 minutes.) Under clear weather she'll sit...and wait.
Thoughts? I'm new here and am in the process of gathering the stuff i need to learn how to fly.
