Difference between Endurance and range?

Endurance is the measure of how long any aerial vehicle can stay aloft, it is a measure of time (hours, minutes, seconds). Range is how far an aerial vehicle can get on a load of fuel, it is a measure of distance (miles, kilometers, yards and meters).

How to Calculate Helicopter Flying Range?

Helicopter Flying Range calculator uses Range of Aircraft = 270*Weight of Fuel/Aircraft Weight*Lift Coefficient/Drag Coefficient*Rotor Efficiency*(Coefficient of Power loss)/Power Specific Fuel Consumption to calculate the Range of Aircraft, The Helicopter Flying Range formula refers to the maximum distance it can travel in a single flight while carrying a specified payload (including fuel, crew, passengers, and cargo), several factors influence the flying range of a helicopter, including fuel capacity, fuel consumption rate, cruising speed, altitude, weather conditions, and payload weight. Range of Aircraft is denoted by R symbol.
