Zero Fuel Weight Calculator

Zero Fuel Weight Calculator calculator can be used to calculate the zero fuel weight of an aircraft based on its empty weight, usable fuel, and fuel consumption.

Input Parameters

Calculation Results

Calculation Formula

Zero Fuel Weight = Empty Weight + Usable Fuel

Where:
Empty Weight: The weight of the aircraft without any fuel
Usable Fuel: The amount of fuel that can be loaded on the aircraft
Fuel Consumption: The rate at which fuel is consumed (used for additional calculations)

Results

Zero Fuel Weight (kg):

0.00

Estimated Flight Time (hours):

0.00

Learn how to use the Zero Fuel Weight Calculator calculator and its working principles

How to Use the Calculator

  1. Enter the Empty Weight of your aircraft in kilograms (kg).
  2. Enter the Usable Fuel available for your flight in kilograms (kg).
  3. Enter the Fuel Consumption of your aircraft in kilograms per hour (kg/hour).
  4. Click the Calculate button to compute the Zero Fuel Weight and estimated flight time.
  5. Use the Reset button to clear all inputs and start over.

Understanding Zero Fuel Weight

Zero Fuel Weight (ZFOW) is the weight of an aircraft when all usable fuel has been consumed. It is an important parameter for flight planning as it helps determine the maximum payload an aircraft can carry for a given flight.

Calculation Formulas

The calculator uses the following formulas:

  • Zero Fuel Weight = Empty Weight + Usable Fuel
  • Estimated Flight Time = Usable Fuel / Fuel Consumption

Example

If your aircraft has an empty weight of 5,000 kg, usable fuel of 1,500 kg, and a fuel consumption rate of 200 kg/hour:

  • Zero Fuel Weight = 5,000 kg + 1,500 kg = 6,500 kg
  • Estimated Flight Time = 1,500 kg / 200 kg/hour = 7.5 hours

Note: This calculator provides a basic estimation and should not be used as the sole basis for flight planning. Always consult with a qualified aviation professional for flight operations.
