What unique information is found on the Weight and Balance report?

The unique information found on the Weight and Balance report relates specifically to the aircraft’s performance characteristics, including the actual unusable fuel and the amount of full oil. These details are crucial for accurately determining the aircraft's weight and center of gravity, which significantly impact its capability to fly safely.

Unusable fuel is the amount of fuel that remains in the tank that cannot be used by the engine, while the amount of full oil is important for maintaining the engine’s proper function and performance. Both factors contribute to the aircraft's total weight and balance, which are essential to evaluate before any flight.

The other options involve aircraft maintenance or limitations but do not pertain directly to the Weight and Balance report. For example, details like the date of the last inspection, flight hours since last maintenance, or the number of passengers allowed are typically found on different types of documentation related to the aircraft’s airworthiness or operational limits rather than on the Weight and Balance report itself.
