The origin of moments in an aircraft is typically defined at a specific reference point where moments (torques) due to forces acting on the airplane are calculated. In the case of the Dassault Falcon 7X, this origin is located at 25% Mean Aerodynamic Chord (MAC). This reference point provides a consistent basis for analyzing the aircraft's balance and stability.

Using the 25% MAC as a reference allows engineers and pilots to accurately assess the aircraft's center of gravity and how it affects performance and control. The choice of 25% MAC is standard in many aircraft designs, as it represents a point forward enough on the wing to provide a meaningful reference for measuring aerodynamic moments without complicating the understanding of the aircraft’s stability characteristics.

Locating the origin of moments anywhere else, such as at the tail section, 75% MAC, or at the cockpit, would not conform to these established aerodynamic principles and could lead to confusion in analyzing the flight dynamics of the Falcon 7X. For example, placing it at the cockpit would not reflect the influence of aerodynamic forces acting on the wings and could make moment calculations inaccurate.
