PCV CPC Case Study 67

-->
Olivia, a bus driver accustomed to older models, is updating her skills to drive modern buses equipped with auxiliary air systems and power-assisted steering (PAS). She needs to understand how these systems improve driving efficiency and safety. Olivia's training includes mastering the use of PAS, which significantly reduces steering effort, and learning about the safety protocols like the deactivation of air-operated accelerators when doors are open. She also needs to be prepared for handling situations where PAS may fail, requiring increased effort to steer.

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. How does PAS enhance driving in modern buses, according to Olivia's training? Give one answer
A It automatically navigates routes
B It controls vehicle speed
C It enhances fuel efficiency
D It lessens steering effort
Correct Answer: D It lessens steering effort
Explanation: PAS primarily lessens the effort needed to steer the bus.
2. What is Olivia taught to do if PAS fails during driving? Give one answer
A Drive faster to compensate
B Keep driving as usual
C Stop and get help
D Switch to manual steering
Correct Answer: C Stop and get help
Explanation: If PAS malfunctions, stopping and getting professional help is advised.
3. How does opening bus doors affect air-operated accelerators, as Olivia learns? Give one answer
A They have no change
B They increase speed automatically
C They may be disabled
D They work more efficiently
Correct Answer: C They may be disabled
Explanation: Air-operated accelerators are often disabled for safety when doors are open.
4. What steering differences does Olivia notice between PAS-equipped and older buses? Give one answer
A Is entirely automated
B Is more complicated
C Requires less physical effort
D Requires more physical effort
Correct Answer: C Requires less physical effort
Explanation: Steering in buses with PAS requires less physical effort than in older buses.
5. What steering system is used in older buses without PAS, as known by Olivia? Give one answer
A A computerized steering system
B A gearing system
C A hydraulic mechanism
D A sensor-based system
Correct Answer: B A gearing system
Explanation: A gearing system aids steering in older buses that lack PAS.
6. How does Olivia approach cornering in historic buses without PAS? Give one answer
A Faster driving
B No adjustment needed
C Slower driving
D Using automated systems
Correct Answer: C Slower driving
Explanation: Driving slower is recommended for navigating corners in historic buses.
7. When is PAS active in buses, as understood by Olivia? Give one answer
A At high speeds only
B In specific weather conditions
C With the engine off
D With the engine running
Correct Answer: D With the engine running
Explanation: PAS is functional when the vehicle's engine is running.
