What is the maximum weight that can be added at Station 150.0 without exceeding the aft CG limit if the aircraft weight is 5,000 lb?

• A. 30.0 pounds
• B. 35.9 pounds
• C. 40.0 pounds
• D. 45.0 pounds

Answer: (B)

To determine the maximum weight that can be added at Station 150.0 without exceeding the aft center of gravity (CG) limit, it is essential to understand how CG is calculated and how weight additions affect the aircraft's balance.

The center of gravity location is influenced by the distribution of the aircraft's weight. When you add weight at a specific station, such as 150.0 inches from the reference point, it changes the overall CG position based on where that weight is added in relation to the aircraft's existing weight.

In this scenario, the existing aircraft weight is 5,000 lb. The calculation typically involves knowing the aircraft's current CG location, the maximum allowable CG limits, and the arm (distance from reference point to weight) for the additional weight you wish to add.

The maximum weight that can be added without exceeding the aft CG limit is calculated based on maintaining the CG within the specified limits. Since the selected answer provided is 35.9 pounds, it is indicative that when this weight is added at Station 150.0, the resultant CG remains within the permitted aft limits.

This means that adding more than this weight would push the CG aft beyond what is acceptable for safe flight, leading to potential stability issues.
