Which weight term excludes engine oil and other drainable fluids and represents the helicopter's basic weight?

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

Answer: (A)

In weight-and-balance calculations, you start from a baseline that represents the aircraft’s basic structure without consumable fluids. This baseline is the licensed empty weight, published by the manufacturer and used as the basic weight of the helicopter. It excludes drainable fluids like engine oil, hydraulic fluid, and other fluids that can be drained, so it shows what the helicopter weighs in its fixed, non-consumable form. From this point, you add the actual fluids you carry (oil, fuel, etc.) and any payload to determine the current operating weight, leading up to the gross and takeoff weights. The other terms describe different concepts: gross weight is the total weight with everything on board at a given moment, takeoff weight is the weight at the moment you lift off, and night refers to a category of operation rather than a weight measurement.
