I'm working on setting up some controls for the default Learjet. I have keys mapped for the battery switch, engine starters, etc. I also have two keys mapped to Engine 1 and 2 fuel valve open/close. The only indication I can find of fuel status in the Learjet is the fuel flow PPH, and the total fuel quantity. Is there anywhere in the panels that shows me whether or not the selected engine has it's fuel valve open or closed? The keys do seem to function, because if I try to start one of the engines with the fuel valve theoretically closed, it will spin up and die back down over and over, but as soon as I open the fuel valve and start it again, after a few seconds of spinning, it catches and the N1 and N2 (as well as Oil PSI and fuel flow) jump up to normal levels. The problem is that I have no visual indication of whether or not the fuel valves are open.
I hope that makes sense. Also, if I am just really misunderstanding some fundamental aspect of the Learjet fuel system, please do not hesitate to let me know!
Thanks!
