PCV CPC Case Study 66

-->
Chris, a long-time driver of traditional buses, is transitioning to driving modern minibuses with auxiliary air systems and power-assisted steering (PAS). He must familiarize himself with the functions and effects of these new systems, understanding their impact on vehicle control and safety. Chris needs to grasp the implications of PAS on steering effort, especially how it operates when the engine is running and the challenges faced if it fails. He also needs to be aware of the safety interlinks, such as the disabling of air-operated accelerators when doors are open.

There are 7 multiple choice questions in this PCV CPC case study. Read this carefully and ensure you fully understand the scenario before starting the test. You need to score 6 out of 7 to pass.

1. What notable PAS feature does Chris learn in modern vehicles? Give one answer
A Automatically steers the vehicle
B Increases steering speed
C Reduces fuel consumption
D Reduces steering effort
Correct Answer: D Reduces steering effort
Explanation: PAS notably reduces the effort required for steering.
2. What action does Chris understand is necessary for a PAS fault? Give one answer
A Continue driving with caution
B Ignore the fault
C Increase engine RPM
D Stop and seek assistance
Correct Answer: D Stop and seek assistance
Explanation: In case of a PAS fault, stopping and seeking assistance is the safest action.
3. How do air-operated accelerators behave with open doors, as Chris discovers? Give one answer
A They increase acceleration
B They may be disabled
C They operate at full capacity
D They switch to manual mode
Correct Answer: B They may be disabled
Explanation: Air-operated accelerators may be disabled for safety when doors are open.
4. How does Chris compare steering in buses with and without PAS? Give one answer
A Less physical effort is needed
B More physical effort is needed
C No difference in effort
D Steering is completely automated
Correct Answer: A Less physical effort is needed
Explanation: Steering with PAS requires less physical effort compared to older buses.
5. In the absence of PAS, what assists steering in older vehicles, as Chris learns? Give one answer
A A gearing system
B Automatic pilot systems
C Electronic steering aids
D Voice control mechanisms
Correct Answer: A A gearing system
Explanation: A gearing system helps in steering older vehicles without PAS.
6. What cornering technique is Chris advised for historic buses? Give one answer
A Accelerating through corners
B Driving at a slower pace
C Relying on PAS
D Using air-operated systems only
Correct Answer: B Driving at a slower pace
Explanation: Drivers are advised to navigate corners at a slower pace in historic buses.
7. When does Chris find PAS operational in modern buses? Give one answer
A Only at low speeds
B Regardless of engine status
C When the engine is off
D When the engine is running
Correct Answer: D When the engine is running
Explanation: PAS is operational when the engine of the bus is running.
