What does the SIC button indicate?

The SIC button indicates "Station in Control Indicator." This term is used in maritime and navigational contexts to refer to a specific status light or display that shows whether a particular station or system is currently in control of the navigation or communication processes on a vessel. It allows crew members to understand which system is actively managing operations, which is essential for coordinating actions and ensuring safe navigation.

This status indicator is vital for maintaining situational awareness, as it helps in identifying which system is being used to control navigation or communication functions. In a multi-station environment, such as on larger vessels where multiple systems and stations may be involved, the SIC provides clarity and aids in effective decision-making during operations.
