Basic empty weight is defined as

Basic empty weight is defined as

• A. The weight of airframe only
• B. Standard empty weight plus full oil
• C. Empty weight minus fuel
• D. Licensed empty weight

Answer: (B)

Basic empty weight is the fixed mass of the aircraft with all standard equipment installed, including a full amount of engine oil. It serves as the baseline for weight-and-balance calculations, from which you subtract payload and add usable fuel to determine the gross weight. The standard empty weight covers the airframe, engines, and fixed equipment, and adding full oil accounts for the lubricant that is always aboard. Usable fuel and payload are considered separately when calculating takeoff weight, so basic empty weight is not just the airframe, nor is it found by subtracting fuel, nor is it the licensed empty weight in this context.
