In aircraft design, fuel quantity refers to the amount of fuel available for use in the aircraft’s fuel tanks. It’s a critical parameter for flight planning, safety, and operational considerations. The formula and SI unit for fuel quantity are as follows:Formula: The formula for calculating fuel quantity is relatively straightforward:
- Fuel Quantity (Q) is the amount of fuel in liters (L) or cubic meters (m³).
- Volume (V) is the volume of fuel in the tank in liters (L) or cubic meters (m³).
- Fuel Density (ρ) is the density of the fuel in kilograms per cubic meter (kg/m³).
