Is there any way to work around or fix the fuel bug? Many of the WWI planes CTD when the AI runs out of fuel... is there a way to avoid this? I set the fuel rate very low, but that is not the best fix

First, make sure you don't "destroy" the fuel tank with the damage model, or "empty" it by cranking up the engSFC to simulate a "fuel leak." Make the engine die instead when the fuel tank damage reaches a certain point, or use fuel tank damage to trigger an obFunc which sets the engineFuelSource to 'none.

I had all kinds of trouble with the Corsair when I was had damage that resulted in the fuel tank emptying.

Beyond that, I have one other idea I haven't tried. Make a "secondary" fuel tank, just a small one, with a gallon or two in it. But don't allow the engine to use this tank as a fuel source (I'm not sure if you actually CAN prevent the engine from using it). Make this tank "indestructible" (no damage properties or obHits). That way, there is always fuel on board the plane, and maybe it won't CTD. Like I said, I haven't tried it yet...

I have found that if you dont calculate the engSFC correctly there tends to be more CTDs when the AI runs out of fuel.

Ok,

Dumb question here, but very important. How do you correctly calculate the engSFC?

Since I am using it in all the engine damage code, this should be double checked to be sure it won't cause any ctd's due to incorrect engSFC settings.

Thanks,

You need to know the weight of one U.S. gallon of fuel and the amount of gallons the fuel tank of the aircraft can carry.

SFC Specifies specific fuel consumption in units of pounds per brake horsepower generated per hour. Brake horsepower is the power at the drive shaft.

In other words, how much gas your plane burns in an hour in relation to the horsepower of the plane.
