Which term refers to the basic empty weight not including full engine oil, with only undrainable oil?

• A. Licensed Empty Weight
• B. Basic Empty Weight
• C. Gross Weight
• D. Night

Answer: (A)

Understanding weight terms used for helicopters hinges on what is included in the baseline empty weight. Licensed Empty Weight is the weight shown on the aircraft’s official documentation and represents the helicopter in its standard configuration with fixed equipment and fluids that cannot be drained. It excludes usable fuel and payload, and specifically accounts for only the undrainable portions of fluids, such as oil that remains after drained oil is removed. That’s why this term matches “the basic empty weight not including full engine oil, with only undrainable oil.” In other words, the licensed empty weight is the official baseline you would start from in weight-and-balance calculations, before adding crew, fuel, and cargo. The other options don’t fit this precise official baseline: Basic Empty Weight is a general term that can differ by manufacturer or context, Gross Weight is the total of everything, and Night isn’t a weight term.
