What is the primary function of fletching on an arrow?

The primary function of fletching on an arrow is to provide stability during flight. Fletching consists of the feathers or vanes attached to the back of the arrow, which play a crucial role in enhancing the arrow's aerodynamics. When an arrow is released, the fletching creates drag that helps to straighten the arrow's flight path, stabilizing it as it moves through the air toward the target. This stabilization is essential for ensuring that the arrow maintains its intended trajectory and reduces any wobbling or spiraling that could affect accuracy.

While increasing accuracy on target (the second choice) is a related benefit of having stable flight, it is not the primary function of the fletching itself. Improved appearance and reduced weight are not the main concerns when considering fletching design; the foremost priority is ensuring that the arrow flies straight and true, which is achieved through effective stabilization. Thus, the correct answer emphasizes the role of fletching in maintaining flight stability, which directly impacts the arrow's performance in reaching its target effectively.
