There is a potential, albeit small, error that could sneak into in the method where the total fuel (usable + unusable) is used as the fuel quantity. The total fuel method assumes that the unusable and usable fuel have the same moment arm. That is not necessarily the case.

I should have clarified that that the fuel capacity for the tanks should be set to the usable quantity, not the total tank capacity.

All that you need to do is edit the aircraft's Weight & Balance template and set the Non-usable Fuel value to 0 gallons. That will remove the unusable fuel item from the calculations. Of course, it's up to you to ensure that the unusable fuel is included in the Empty Weight.
