Methodology
Range equals the total flight hours (fuel capacity divided by consumption) multiplied by speed. Endurance equals the available flight hours directly from the fuel burn rate.
- Endurance expresses how long the aircraft can remain airborne at the given fuel burn.
- Range multiplies endurance by speed to show the total achievable distance.
- Speed, capacity, and burn rate are assumed constant for the entire duration.

Data Source and Methodology
The formulas are standard aerospace engineering derivations, with additional reference from Aviapages.
The Formula Explained
Range: \(\frac{FuelCapacity}{FuelConsumption} \times Speed\)
Endurance: \(\frac{FuelCapacity}{FuelConsumption}\)
Glossary of Variables
- Fuel Capacity: Total fuel on board.
- Fuel Consumption: Fuel burned per hour.
- Speed: Cruise speed used to compute range.
- Range: Maximum distance achievable.
- Endurance: Maximum time airborne.
Example Calculation
With 5000 liters of fuel, burning 250 liters/hour at 600 km/h, range is 12,000 km and endurance is 20 hours.
Frequently Asked Questions (FAQ)
What is the significance of range in aviation?
Range determines how far an aircraft can fly without refueling.
How is endurance different from range?
Endurance focuses on time, while range focuses on distance.
Can this calculator be used for all aircraft?
Yes, so long as you know the relevant fuel parameters.
What factors affect fuel consumption?
Weight, weather, engine efficiency, and altitude all influence burn rate.
Is this calculator compliant with aviation standards?
It follows standard aerospace engineering formulas commonly used in flight planning.
