FOB, FUEL RESERVE etc

Good afternoon gentlemen (and ladies),

First time posting on this forum. I cant believe I stumbled onto this forum by chance. Incredible wealth of knowledge here!

Anyway, I write programs & speadsheets for Aviation & Electronics stuff. I have a question about the term "Fuel Reserve" & Fuel on Board. I'm working on a block of code for fuel data/endurance information.

For instance;

Fuel Reserve / Fuel Flow = Endurance in Hours

Does Fuel Reserve and/or Fuel on Board mean only "usable fuel"? Or, does it include the "unusable fuel" in the fuel system?

If an airplane has 50-Gal fuel capacity, of which 48-Gal is "usable", do I use 48-Gal as my Fuel Reserve/Fuel on Board value?

Just want to be sure I'm using the term correctly.

Thanks
