Question 1 of 205eccef9cbacbc34ba4d45a55

When the helm angle position is changed in the wheel house, a series of corresponding events of the steering gear will occur and include the following: The length of time the steering gear pump remains on stroke is proportional to helm angle input System pressure will be higher when the vessel is operating "full astern"

🔍 Key Concepts

• How a hunting (follow-up) steering system keeps the rudder moving until the ordered helm angle is reached • What determines how long a variable-displacement steering pump stays on stroke when you put over the wheel • How propeller wash and shaft power ahead vs. astern affect hydraulic steering system pressure

💭 Think About

• For statement I, think about what the pump must do when you order a very small helm change versus a large helm change. Will the pump need to stay on stroke the same amount of time in both cases? • For statement II, compare how hard the steering gear has to work when the rudder is deflecting a strong ahead thrust versus a reduced or disturbed flow when engines are full astern. • Ask yourself in which engine condition the rudder is more ‘loaded’ by water flow: high-speed full ahead, or full astern where flow patterns and speed over the rudder are different?

✅ Before You Answer

• Check how a follow‑up steering system stops the pump: does it shut off by time, or by matching ordered vs. actual rudder angle? • Confirm under which propulsion condition (full ahead or full astern) the flow over the rudder — and thus rudder torque and hydraulic pressure demand — is generally greatest. • Verify that "system pressure" in this context is mainly a function of rudder torque (load), not simply engine telegraph position.
