Where would you find the empty weight of an airplane?

• A. In the illustrated parts catalog.
• B. In the aircraft weight and balance manual.
• C. In the AMM.
• D. In the structural repair manual.

Answer: (B)

The main idea is where official weight data for the aircraft is published. The empty weight is documented in the Aircraft Weight and Balance Manual, which is the source that lists the baseline weights, moments, CG limits, and loading data used to calculate how the airplane sits in terms of balance. The illustrated parts catalog is for parts identification, not weight data. The Aircraft Maintenance Manual covers maintenance procedures, not weight and balance figures. The Structural Repair Manual focuses on repair procedures and structural limits, not the aircraft’s weight. So the best place to find the empty weight is the Weight and Balance Manual.
