Which canopy size will exhibit quicker control response for the same model design?

The correct choice is the one that aligns with the general principle of canopy size relative to the jumper's weight and the design characteristics of the canopy. A smaller canopy size is designed to be more responsive and will generally provide quicker control response for the same model design compared to larger canopies.

In this context, the choice that reflects a smaller canopy relative to the jumper's weight is option D. A 130-square-foot canopy paired with a 130-pound jumper is smaller than the other options, which leads to faster control inputs and a more agile response in the air.

When comparing all choices, a smaller canopy has less surface area for the same amount of weight, which allows for quicker handling. Therefore, when a canopy is smaller than the jumper's designated load factor, it will exhibit a more responsive behavior. This is particularly significant during maneuvers such as turns and other adjustments in flight. The other options with larger canopies will generally respond more slowly to input due to increased drag and surface area.

Thus, a 130-square-foot canopy for a 130-pound jumper will exhibit a quicker control response than the others, confirming its position as the correct response in this scenario.
