Give the PC-7 a capacity of 474 liters of fuel
The file Aircraft/pc7/specifications says the PC-7 can hold 474
liters of fuel. At 15°C and about 0.8g/cm^3 that corresponds to
379kg of jet fuel. 379 kg are 836 lbs, and those 836 lbs distributed
evenly into two fuel tanks makes for 418 lbs of fuel per tank.
This also requires the instrument scale to be adapted, to distribute
those 420 pounds over 300 degrees instead of 2000 pounds. However,
the image used for the instruments still shows a scale which just
goes from "0" via "1" to "2". Someone else will have to fix that.
As an additional check for the correctness of this, the effective
range you get with this patch is reasonably similar to the numbers
given in the "specifications" file.
