Loading limitations shall include which elements?

• A. All limiting mass and centres of gravity
• B. All limiting mass, centres of gravity position, mass distributions and floor loading
• C. All limiting mass, centres of gravity position and floor loading
• D. All limiting mass, mass distributions and centres of gravity

Answer: (B)

Loading limitations cover more than just the total weight. They require controlling the maximum mass and where that mass sits, because the center of gravity position directly affects stability, controllability, and structural loading. Mass distributions matter because how mass is spread across the aircraft changes moments about the CG and influences both stability and the loads the structure must bear. Floor loading is essential because the floor structure has finite strength and must be able to support the weight without overstressing at any cargo or passenger configuration. Taken together, all four aspects—limiting mass, centre of gravity position, mass distributions, and floor loading—define the safe loading envelope.
