What mode are LCUs usually in when not actively engaged in steering?

When not actively engaged in steering, LCUs (Landing Craft Utility) are typically in local mode. In local mode, the controls are engaged directly on the craft itself, allowing crew members to monitor and manage various functions without the complexities that come with remote operation. This arrangement ensures that the crew can interact with the vessel’s systems directly, providing immediate feedback and control when necessary, such as when preparing to steer or maneuver the craft.

In contrast, remote mode would mean that controls are operated from a distance, which may not be suitable when the vessel is not in active operation. Similarly, the disabled mode implies that the systems are not operable or offline, which doesn’t reflect the operational readiness expected of LCUs. Lastly, manual mode refers to hand-on involvement in operation but doesn't specifically define the state of steering engagement as effectively as local mode does. Therefore, local mode is the optimal setting for LCUs that are not currently steering, facilitating a smooth transition to active duties when needed.
