So I've been figuring out how to get the plane (NGX 737) from cold and dark to engine start, but after a few steps I already run into a problem.
When I want to start the APU the needle(EGT) moves really slow towards 4, and doesn't go any higher or lower and also at that point the "Low oil pressure" light comes on. (Nothing weird about that since that's normal I guess). But the problem is that it won't go out. It only goes out if I turn the APU on and off.
So to make it clear, from the point that it reaches the 4 mark the APU gen off buss also goes on and when I click it the APU start (I think I'm not sure, but it sounds like it.)
But why doesn't the "Low oil pressure" light go off?
