According to safety standards, what should control operations in a launch and recovery system (LARS) under normal conditions?

The correct choice emphasizes that the drive system should control operations in a launch and recovery system (LARS) under normal conditions because it is designed to provide the necessary power and functionality to safely maneuver equipment during launching and recovering activities. A drive system ensures that operations are efficient and reliable, which is essential for minimizing risks and ensuring safety in a dynamic underwater environment.

Utilizing a dedicated drive system allows for consistent control and smooth operation, as it is engineered to handle the mechanical demands and environmental challenges encountered during these processes. The reliability of the drive system is fundamental for the safe handling of divers and equipment, facilitating accurate movements in both ascent and descent.

In contrast, while brakes can certainly contribute to interfacing and controlling the system during specific scenarios, they are generally not the primary mechanism for normal operations. Manual force may be necessary in auxiliary or emergency situations but is not a preferred method for standard control since it lacks the precision and reflexes of a mechanized system. Similarly, the emergency system, while critical for safety during unexpected situations, is not intended for regular operations and is activated only when there is a malfunction or an adverse condition that jeopardizes safety. Thus, the focus on the drive system indicates a prioritization of safety through reliable engineering practices.
