What is the location of the center of gravity (CG) if 146 pounds are removed from Station 150?

• A. 75.4
• B. 80.6
• C. 82.0
• D. 78.5

Answer: (B)

To determine the location of the center of gravity (CG) after removing 146 pounds from Station 150, it is essential to understand how the weight change affects the overall CG location. The center of gravity represents the point where the total mass of the aircraft is concentrated, and adjusting the weight at a specific station will alter this point.

When weight is removed from a particular station, it is necessary to calculate its effect on the CG. The process typically involves using moments, which are the products of the weight and its distance from a reference point (usually the nose of the aircraft or another designated point). By calculating the moments before and after the weight is removed, the new CG can be established.

In this case, removing weight from Station 150 affects the total moment about the CG. This adjustment will usually result in a shift of the CG towards the front (or nose) of the aircraft if the weight is removed from the tail section or further back in the fuselage.

Choosing 80.6 as the new CG location suggests that this calculated point is a result of balancing the moments around the remaining weights. This means that 80.6 is the new position where the aircraft’s total weight is effectively centered after accounting for the removal of the
