Account for fuel burn” in aircraft design refers to calculating the amount of fuel consumed by an aircraft during a specific phase of flight or over a certain distance. This calculation is crucial for flight planning, performance analysis, and ensuring that the aircraft carries enough fuel to reach its destination safely. There isn’t a single formula for fuel burn, as it depends on various factors, but I can provide a general overview of the concept:
- Fuel Flow Rate (FFR): This is the rate at which the aircraft’s engines consume fuel. It’s typically measured in liters per hour (L/h) or gallons per hour (gal/h) and varies depending on engine type, thrust settings, and altitude.
- Time: The duration of the flight or the specific phase of flight you’re interested in, usually measured in hours (h).
