How much weight must be shifted from Station 150.0 to Station 30.0 to move the CG to exactly the aft CG limit when the total weight is 7,500 lbs?

How much weight must be shifted from Station 150.0 to Station 30.0 to move the CG to exactly the aft CG limit when the total weight is 7,500 lbs?

• A. 75 pounds
• B. 62.5 pounds
• C. 50 pounds
• D. 70 pounds

Answer: (B)

To determine how much weight must be shifted to achieve the desired center of gravity (CG) location, it's essential to understand the concept of moment arms and how shifting weight impacts the overall balance of the aircraft. First, you need to use the formula for calculating the moment. The moment is the product of the weight and its distance from a reference point (in this case, the reference point would typically be Station 0). The CG is determined based on the total moments generated by all weights distributed along the length of the aircraft. Given that the total weight is 7,500 lbs, you find the current location of the CG. This involves calculating the moments from all the stations where weight is located (in this scenario, primarily at Station 150.0) and knowing the target weight must be shifted to Station 30.0. When you shift weight from a forward station (150.0) to a rearward station (30.0), you are effectively increasing the moment arm, which moves the CG toward the aft. The goal is to reach the aft CG limit while carefully managing the weight to maintain stability. The calculation can be simplified by finding out how the weight affects the CG. The weight shifted needs to create sufficient additional moment to
