While steering by autopilot you notice that the vessel is deviating from the given course and there is no follow up with corrective rudder action to return to the proper heading. The emergency operating procedure should require you to immediately change operation from __________.
β’ Understand the difference between gyro, control, and hand modes on an autopilot/steering system β’ Know what the emergency procedure is when the autopilot fails to apply corrective rudder β’ Identify which mode gives you direct manual control of the rudder/steering gear in an emergency
β’ If the autopilot is not giving follow-up rudder, what is the safest way to ensure you can immediately steer the vessel yourself? β’ Which mode bypasses automatic steering functions and allows the helmsman to command the rudder directly? β’ Think about which mode you would use if all automatic control logic became unreliable or failed.
β’ Verify which mode corresponds to manual steering at the helm β’ Confirm which modes rely on the gyro input and autopilot control circuits to move the rudder β’ Ask yourself: in an emergency, do you want to rely on automatic signals, or have direct control of the rudder from the wheel/joy stick?
