At what weight does the Cessna 152 reach its maximum useful load?

The maximum useful load for the Cessna 152 is defined as the difference between the maximum takeoff weight and the empty weight of the aircraft. The Cessna 152 typically has a maximum takeoff weight of approximately 1,600 pounds and an empty weight of around 1,034 pounds.

To find the maximum useful load, you subtract the empty weight from the maximum takeoff weight:

1,600 lbs (maximum takeoff weight) - 1,034 lbs (empty weight) = 566 lbs (maximum useful load).

This accurate calculation aligns with the provided answer, which indicates that 566 lbs is the maximum useful load the aircraft can carry. Therefore, B is the correct answer.
