✈️ A320 Fuel Distribution Calculator – A Complete Guide

Maintenance of an Airbus A320 involves a lot more than just repairing or replacing parts. One critical aspect of aircraft operations is refueling of the aircraft. For flight dispatchers, ground staff, and even pilots, understanding how fuel is distributed across tanks is essential — not only for performance and balance but also for safety and compliance.

This blog introduces a web-based A320 Fuel Distribution Calculator, specifically designed to help aviation professionals calculate and visualize fuel distribution before and after refueling. 

🧮 What This Calculator Does

The calculator allows you to:

• Input arrival fuel, uplift in liters, specific gravity, and departure fuel.

• Calculate the distribution of fuel across 4 tanks: LH (Left Wing), RH (Right Wing), CTR (Center), and ACTR (Auxiliary Center Tank).

• Display the total arrival and departure fuel.

• Show the actual uplift in KG.

• Compute the difference (Y - X) between arrival and departure fuel.

• Calculate and show the discrepancy and discrepancy percentage.

• Display live UTC time at the time of calculation.

• Customize maximum tank capacities, keeping within aircraft limits.

🧑‍🏫 How to Use the A320 Fuel Calculator – Step-by-Step

Follow these simple steps to calculate and verify fuel distribution:

🔹 Step 1: Input Arrival Fuel in KG

Enter the total fuel available on arrival.

🔹 Step 2: Enter Specific Gravity

This is usually provided by the fuel supplier (commonly around 0.8). It’s used to convert uplift in liters to kilograms.

🔹 Step 3: Input Uplift Fuel in Liters

Enter the total uplift provided at refueling in liters.

🔹 Step 4: Input Departure Fuel in KG

Enter the expected or final departure fuel after refueling.

🔹 Step 5: Customize Tank Capacities (Optional)

Set maximum capacities for LH, RH, and CTR tanks. These cannot exceed:

• LH & RH: 6100 KG each

• CTR: 6400 KG

🔹 Step 6: Click “Calculate”

Click the button to compute fuel distribution and differences.

🔹 Step 7: Review the Results

You will see a neat table like this:

Tank	Arrival Fuel (KG)	Departure Fuel (KG)
LH	3050	3050
CTR	2400	3200
ACTR	300	1200
RH	3050	3050
Total	8800	10500

Below the table, you’ll also see:

• Actual Uplift (Uplift Liters × Specific Gravity)

• Fuel Difference (Y - X)

• Discrepancy between expected and actual uplift

• Discrepancy % – a valuable check for refueling consistency

• Live UTC Time – Timestamp of the calculation

✅ Why This Calculator Matters

• Ensures accurate fuel distribution per Airbus priority (LH/RH > CTR > ACTR)

• Helps verify refueling records

• Detects discrepancies in fuel uplift vs. difference

• Makes manual calculations fast and error-free
