In flight mechanics, “range” refers to the horizontal distance an aircraft can travel without the need for refueling. It is a crucial performance parameter and is a measure of the endurance and fuel efficiency of an aircraft. Ranges are typically expressed in units such as nautical miles or kilometers. Mathematically, the range can be calculated using the formula:
Where:
- E is the Endurance in sec.
- V∞ is the freestream Velocity in m/s.
