🔍 Key Concepts

• Electro-hydraulic steering systems: how power units are controlled normally vs. in emergency • Difference between remote/automatic steering from the bridge and local/manual control at the steering gear • What part of the system lets you bypass the automatic/follow-up system and move the rudder directly

💭 Think About

• Which component would a crew member physically use at the steering gear room to move the rudder if the usual bridge controls failed? • Which option names a control device (something you turn or operate) instead of a mechanical linkage or internal gear arrangement? • Think about steering redundancy: what simple backup control would be installed so you can still steer even if electrical control circuits or follow‑up systems fail?

✅ Before You Answer

• Identify which choice is specifically used for manual/emergency control rather than normal automatic operation • Eliminate any option that mainly describes mechanical linkage inside the steering system instead of an operator’s control handle/wheel • Confirm which device is typically located at the steering gear in the steering gear room and allows direct operation of the electro‑hydraulic units

In an emergency, the electro-hydraulic steering units can be directly controlled by the __________.
