What is located in the center of the UH-60A?

The Floor Mounted Anchor Line System is located in the center of the UH-60A. This system is crucial for airborne operations, as it provides a secure attachment point for jumpers exiting the helicopter. It ensures that parachutists can exit safely in a controlled manner, maintaining their formation and ensuring the proper deployment of their parachutes.

While the other options present important features and equipment within or related to the UH-60A, none occupy the central position in the aircraft as the Floor Mounted Anchor Line System does, which is specifically designed for tactical operations involving personnel jumps.
