Which item is NOT part of the published envelope that AFM limitations apply to?

• A. Weight, CG, and configuration
• B. Paint color
• C. Fuel type
• D. Cabin layout

Answer: (B)

The published envelope that AFM limitations apply to is defined by weight, center of gravity, and the configurations the airplane is permitted to operate with. Weight and CG determine structural loads, stability, and the accuracy of performance data, while configuration covers the installed equipment and seating layouts that can shift how the weight is distributed. Paint color does not affect weight distribution, aerodynamics, or structural loads in normal operation, so it isn’t part of the envelope. Cabin layout falls under configuration because changing seating or equipment changes where weight sits and can alter the CG.
