Carrying this over from the SF1 KB...



When dealing with military a/c, several types of fuels have been used throughout the years, and each has it's own density. Depending on how in-depth you want to be with your a/c or drop tanks, here are the service years, branches, and densities for jet fuels:



JP-4 Density = 6.5 lb/gal (1951 - 1995, Primarily used by the USAF)

JP-5 Density = 6.8 lb/gal (1952 - Present; projected to 2025, Primarily used by the USN, and other navies)

JP-7 Density = 6.6 lb/gal (used by the SR-71)

JP-8 Density = 6.7 lb/gal (1996 - Present, Primarily used by the USAF)


Jet-A Density = 6.70 lb/gal (used by civil turbines)


*These densities are for a temp of 15 degrees C / 59 degrees F. (API density)



1x F-111 External 600gal Tank holds 3900lbs [600 x 6.5 = 3900] of JP-5 (I'm using JP-4 since that's what was in service at that time).


Now, to insert the fuel weight into the game, it must be converted from pounds to kilograms:

3900 (lbs.) x.45 = 1755 (kgs).


Once you've converted the weight, insert it into the 'Capacity' box in the 'Fuel Tank Data' section in the weapons editor.






Depending on what your references are, you may get your fuel capacities in gallons, or pounds or both (or in metric is applicable). Second to having a full breakdown of fuel capacities, I prefer gallons since you can just multiply by the density, and then convert to kilograms.


Below is a file with some fuel capacities to get you on your way. If you have any information, please PM me as I'm compiling a list.
