Aircraft Fueling Calculator – A320 / B737

Aircraft fueling calculator with left-wing (LH) tank, right-wing (RH) tank, and center (CTR) tank. It can be used for Airbus A320 and Boeing 737 aircraft.

Simply input the Arrival Fuel (KG), Specific Gravity, Uplift (L), and Departure Fuel (KG) along with your Wing Tank Limit (KG) to get precise calculations for arrival and departure fuel distributions, actual uplift, and discrepancy percentages.

Set Wing Tank Limit: Enter the limit for each wing tank. For example, for Airbus A320, we usually fill 6000 kg in each wing tank. Similarly, for Boeing 737 MAX, we fill 3700 kg in each wing tank. This will allow the calculator to distribute the departure fuel equally between the LH and RH tanks, with any excess fuel going into the CTR tank.

Actual Uplift (KG): The actual uplift in kilograms is obtained by multiplying the uplift in liters (L) by the specific gravity (SG) of the fuel. Actual Uplift KG = L × SG

Calculated (KG): The calculated KG is the difference between the total departure fuel (Y) and the total arrival fuel (X). Calculated KG = Total Departure Fuel (Y) − Total Arrival Fuel (X)

Discrepancy: Discrepancy is the difference between the calculated (Y - X) KG and the actual uplift KG. Discrepancy = Calculated (Y - X) KG − Actual Uplift KG

DISCREPANCY % = (CALCULATED KG - ACTUAL UPLIFT KG) / CALCULATED KG x 100
