What should be clearly indicated on the aircraft weighing form?

• A. Minimum allowable gross weight
• B. Weight of unusable fuel
• C. Weighing points
• D. Datum reference used

Answer: (C)

The key idea is to designate exactly where the aircraft is weighed. The weighing points are the specific locations on the aircraft where scales or load cells are attached to capture the true weight and its distribution. Clearly indicating these points on the weighing form ensures the measurements correspond to the correct structural locations, so the total weight and the moments used to calculate the center of gravity are accurate and repeatable. If the weighing points aren’t marked, measurements could be taken at inconsistent spots, leading to incorrect weight and balance data even with precise scales. Other items aren’t what the form primarily serves: minimum allowable gross weight is a design limit, not something determined by the weighing process; the weight of unusable fuel is part of the aircraft’s total weight but not the essential labeling on the weighing form; datum reference is used for calculating moments, but the crucial labeling for correct weighing is the identification of the weighing points.
