Calculate aircraft range using usable fuel, fuel flow, groundspeed, and optional reserve fuel. This free aviation calculator helps pilots estimate how far an aircraft can travel for planning and fuel management.
Enter usable fuel, fuel flow, groundspeed, and optional reserve fuel to estimate total range and range after reserve.
This calculator estimates practical range using groundspeed, which makes it useful for real-world flight planning.
Range is the distance an aircraft can travel with the fuel available under the planned conditions. It depends on both endurance and groundspeed.
Pilots often use range calculations to estimate whether a route is realistic with the available fuel, while still keeping reserve fuel protected for safety and regulatory requirements.
Groundspeed is usually the most practical speed for route planning because it reflects actual progress over the ground.
No. Endurance tells you how long the aircraft can remain airborne. Range tells you how far it can travel.
Use usable fuel, unless the aircraft documentation states that all fuel is usable.
Yes. Wind changes groundspeed, and that directly affects range. A headwind reduces range over the ground, while a tailwind increases it.
