My favorite plane is the I am currently flying RTW with it, and at the start, I had to make an emergency fuel stop after only flying The Beech stats online say the bird has a range of around 1,800 Nm, so I changed the fuel flow scalar from 1.0 to .17 to get it in that ballpark range. Now the fuel guage reads FULL after traveling 1500 nm! How can I fix it to go down realistically? I saw somewhere that if you up the thrust scalar, it will, but I don't know..... TIA Alex

Are you correctly setting the angle of the props and metering the fuel? If you keep the props on fine pitch and the fuel running at full tilt then that is about the maximum range you'll get!

I just remember the first time I flew it in FS I forgot (and me a guy that had gained a PPL) to set the prop to coarse pitch and adjust the fuel. I wanted to do London-Budapest and bombed on the Franco-German border (I hadn't flown for 8 years and my dead-stick landings sucked right up to the point when I crashed into the old ladies kitchen for lunch)

For an initial FFS of 1.0, it would be:

Reciprocal of published range / actual range x fuel flow scalar.

So if the published plane range is say 2000 miles and you actually fly 3000 miles, the it would be the reciprocal of 2000/3000x1 - in other words 1.49.  So the FFS would then be re-set to 1.49. This means that the plane is now using 1.49x as much fuel and therefore goes 2/3 the distance on it.

You can then test it out to make sure it's accurate. It'll be pretty accurate to two decimal places, which I guess is all you need as real world weather, speed etc. will make any more accuracy almost irrelevant.
