Fuel Density Calculation is a cockpit utility for comparing receipt-based fuel uplift calculations against indicated fuel on board. Enter landing fuel, fuel density or specific gravity, fuel receipt quantities, and indicated FOB. The app calculates uplift, landing fuel plus uplift, and the resulting difference in both percent and pounds. Supports gallons and liters, automatic decimal formatting, and specific gravity conversion for receipts that provide SG instead of fuel density. This app is a calculation aid and does not replace approved aircraft, company, or maintenance procedures.
