In aircraft design, endurance refers to the maximum amount of time an aircraft can remain in flight on a given fuel load. The formula for endurance is as follows:
- Endurance (E) is measured in hours (h).
- Fuel Quantity (Q) is typically measured in liters (L) or gallons (gal) depending on the system.
- Fuel Flow Rate (F) is the rate at which the aircraft consumes fuel and is measured in liters per hour (L/h) or gallons per hour (gal/h).
