Empty Weight Empty weight is defined as the total weight of an aircraft including all fixed ballast, unusable fuel, undrainable oil, total quantity of engine coolant and total quantity of hydraulic fluid, and excluding crew, payload, usable fuel and drainable oil.
Everything Explained: Weight and Balance
Key Takeaways:
- The article defines various aircraft weights, including Empty Weight, Basic Operating Weight, and Useful Load, emphasizing the Maximum Allowable Zero Fuel Weight (MZFW) which protects against excessive wing-bending stress.
- Aircraft balance is determined by the Center of Gravity (CG), calculated using a system of Datum (reference line), Station (location), Arm (distance from datum), and Moment (weight multiplied by arm).
- Maintaining the aircraft's Center of Gravity (CG) within specified forward and aft limits is crucial for safe flight, with its position sometimes expressed as a percentage of the Mean Aerodynamic Chord (MAC).
