Who establishes the standard gross weight as a limiting value for an aircraft?

• A. The manufacturer
• B. The pilot
• C. The airport authority
• D. The maintenance crew

Answer: (A)

The limit is set by the aircraft designer and manufacturer. They determine the maximum weight the airframe, wings, and structure can safely handle, based on structural strength, balance, and performance margins gathered during certification. This value is then approved by the aviation authority and published in the aircraft’s flight manual and type certificate data sheet. Pilots and operators must plan and operate within this published limit, along with other limits like maximum takeoff weight and zero-fuel weight. The airport authority and maintenance crew don’t establish this limit; the pilot operates within it, and maintenance ensures the aircraft remains airworthy within those bounds.
