Certified Flight Instructor - Flight Instructor Airplane Practice Exam

How much weight must be shifted to move the CG to the aft CG limit?

1. 68.9 pounds.

2. 65.8 pounds.

3. 62.5 pounds.

4. 70.0 pounds.

The correct answer is: 62.5 pounds.

To determine how much weight must be shifted to move the center of gravity (CG) to the aft CG limit, it's essential to understand the relationship between weight distribution and CG location. The CG is essentially the balance point of the aircraft, and it must be within specified limits for safe flight operations. The correct answer reflects the specific calculation required to adjust the CG from its current position to the aft limit. This involves knowing the existing CG position, the total weight of the aircraft, and how far back the desired CG location is. In this case, the value of 62.5 pounds indicates that moving this amount of weight to the rear of the aircraft will achieve the desired CG position at the aft limit. The numbers provided in the other options represent different weight amounts that may not be appropriate for shifting the CG to the aft limit. Each of these weights would either shift the CG too far back (beyond the aft limit) or not enough to reach the specific aft limit, illustrating the importance of precise calculations in weight and balance scenarios for flight safety. Understanding these calculations is crucial for flight instructors and pilots to ensure that aircraft are loaded within safe limits, directly impacting performance and handling characteristics during flight.
