Aux 1 Unit 9 Q10

1 / 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.

A) The autopilot system disengages and requires manual correction.

C) The vessel’s speed is automatically increased.

2 / 10

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

A) To reduce the workload on the autopilot system

C) To increase the speed of the vessel

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

D) To decrease fuel consumption

3 / 10

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

A) The rudder angle indicator

C) The engine telegraph

B) The gyrocompass or heading sensor

D) The wind vane

4 / 10

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

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

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.

5 / 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.

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

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

6 / 10

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

A) To adjust the vessel’s speed

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

D) To control the fuel consumption of the vessel

C) To increase the hydraulic pressure in the system

7 / 10

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

C) By changing the vessel’s heading manually

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

A) By adjusting the vessel’s speed

D) By reducing engine power

8 / 10

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

A) They provide electrical power to the autopilot system

D) They adjust the vessel’s speed

9 / 10

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

A) The autopilot continues to operate alongside manual controls.

D) The steering gear automatically locks in place.

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

C) The autopilot increases the vessel's speed.

10 / 10

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

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

D) To control the engine power output

C) To increase the speed of the vessel

A) To manually control the steering gear
