Which of the following systems utilizes chilled water?

Chilled water systems are commonly used in various applications where temperature control is critical for operational efficiency and comfort. In the context of the options provided, all of the systems mentioned can incorporate chilled water for cooling purposes.

Combat consoles often require precise temperature control to protect sensitive electronic components and maintain optimal operational conditions, necessitating a reliable cooling system. Chilled water systems are used to provide this cooling within the consoles.

FCA's, or Fuel Control Actuators, operate in environments where maintaining low temperatures is crucial for their functionality and reliability. The use of chilled water can help dissipate heat generated during their operation, ensuring they work efficiently.

Steering Hydraulic Power Units (HPUs) also benefit from using chilled water systems. High temperatures can affect the viscosity of hydraulic fluids, leading to inefficient operation, increased wear, or failures. Chilled water systems help maintain appropriate temperatures for these hydraulic systems to function optimally.

Given that all these applications can effectively utilize chilled water for cooling, it is accurate to say that all the options provided utilize chilled water systems.
