The maximum weight as used in weight and balance control of a given aircraft can normally be found

• A. Aircraft Specification
• B. Type Certificate Data Sheet
• C. Both Aircraft Specification and Type Certificate Data Sheet
• D. Flight Manual

Answer: (C)

The maximum weight used for weight and balance is a fixed part of the aircraft’s type design, published by the manufacturer and approved by the regulator. It appears in both the Aircraft Specification (the design data from the manufacturer) and the Type Certificate Data Sheet (the regulator’s public record of the approved type design). These are the official sources for limits like maximum takeoff weight, maximum landing weight, and related weight envelopes.

The Flight Manual may show weight and balance data for planning and in-flight reference, but it does not establish the official limits; it typically reiterates the values shown in the Aircraft Specification and the Type Certificate Data Sheet. So the best answer is that the maximum weight can normally be found in both the Aircraft Specification and the Type Certificate Data Sheet.
