Aux 1 Unit 9 Q10

1 / 10

Which component of an automatic steering system detects deviations from the set course?

D) The wind vane

C) The engine telegraph

B) The gyrocompass or heading sensor

A) The rudder angle indicator

2 / 10

How does an autopilot system interact with a valve-operated steering gear system to control the vessel's heading?

A) The autopilot directly moves the rudder without involving the steering gear.

D) The autopilot only monitors the heading and requires manual adjustment of the steering gear.

C) The autopilot increases the vessel’s speed to correct the heading.

B) The autopilot sends electrical signals to the servo valves in the steering gear, which control the hydraulic fluid flow to move the rudder.

3 / 10

What happens when the autopilot system detects that the vessel is deviating from its set course?

B) The autopilot system adjusts the rudder position to correct the course.

D) The autopilot system sounds an alarm but does not correct the course.

C) The vessel’s speed is automatically increased.

A) The autopilot system disengages and requires manual correction.

4 / 10

What role do servo valves play in a valve-operated steering gear system?

A) They provide electrical power to the autopilot system

B) They control the flow of hydraulic fluid to the steering gear rams based on signals from the autopilot

C) They increase the pressure of hydraulic fluid

D) They adjust the vessel’s speed

5 / 10

What happens to the automatic steering system when the vessel enters manual steering mode?

B) The autopilot disengages, and the crew has full control over the steering gear.

D) The steering gear automatically locks in place.

A) The autopilot continues to operate alongside manual controls.

C) The autopilot increases the vessel's speed.

6 / 10

In an automatic steering system, what is the function of the feedback mechanism?

A) To adjust the vessel’s speed

D) To control the fuel consumption of the vessel

C) To increase the hydraulic pressure in the system

B) To provide real-time information to the autopilot about the current rudder angle

7 / 10

What ensures that the steering gear responds accurately to the commands from the autopilot system?

B) A feedback loop from the rudder position sensor provides real-time data to the autopilot.

D) The vessel’s heading is manually adjusted by the crew.

A) The vessel’s speed is maintained at a constant level.

C) The autopilot system operates independently of the steering gear.

8 / 10

Why is it important to have manual override capabilities in an automatic steering system?

C) To increase the speed of the vessel

A) To reduce the workload on the autopilot system

D) To decrease fuel consumption

B) To allow the crew to manually control the steering in case of autopilot malfunction or in situations requiring human judgment

9 / 10

What is the primary function of an autopilot system in an automatic steering system?

D) To control the engine power output

B) To automatically maintain a vessel on a set course with minimal human intervention

A) To manually control the steering gear

C) To increase the speed of the vessel

10 / 10

How does the autopilot system correct course deviations in an automatic steering system?

A) By adjusting the vessel’s speed

B) By sending signals to the steering gear to move the rudder in the appropriate direction

D) By reducing engine power

C) By changing the vessel’s heading manually
