🔢 What is the A320 / A321 Fuel Calculator?

The Fuel CLC (Calculation Logic Controller) is a web-based aviation tool designed to:

• Convert uplift from liters to kilograms

• Distribute fuel across LH, RH, CTR, ACT, and RCT tanks

• Validate fuel correctness with automatic discrepancy checks

• Support ACT (Additional Center Tank) operations

• Simulate realistic Airbus fuel distribution logic

It is especially useful for A321 XLR and long-range planning scenarios.

🧮 How This Fuel Calculator Works

The calculator follows realistic Airbus-style logic:

1️⃣ Input Section

You enter:

• Required Fuel (kg) – Total departure fuel

• Uplift (Liters) – Fuel to be uploaded

• Specific Gravity (SG) – Default set to 0.80

• ACT ON/OFF – Enable or disable ACT tank

2️⃣ Automatic Conversion

• Uplift liters are converted to kilograms

• Fuel is rounded to the nearest 20 kg, reflecting operational practice

3️⃣ Fuel Distribution Logic

Fuel is split and distributed in the following order:

1. Wing Tanks (LH & RH) – Evenly balanced

2. CTR (Center Tank)

3. ACT (if enabled)

4. RCT (Rear Center Tank)

All tank values respect maximum capacity limits set in the calculator.

📊 Output Explained

The main table shows:

• Arrival Fuel (kg) – Fuel remaining before uplift

• Uplift Fuel (kg) – Fuel added per tank

• Departure Fuel (kg) – Final fuel distribution

A total summary row confirms:

• Total arrival fuel

• Total uplift

• Total departure fuel

The system automatically checks accuracy and displays:

• ✅ Fuel distribution correct
  or

• ⚠ Fuel discrepancy detected

⚙️ Adjustable Tank Capacity Settings

This calculator allows manual customization of:

• Wing tank capacity (5500 / 6000 kg)

• CTR capacity

• ACT capacity

• RCT capacity

This makes it suitable for different A320 / A321 variants, including XLR configurations.
