Diagnosing Propulsion System Faults

How can faults in propulsion systems be diagnosed effectively?

• By guessing based on past experiences

• By collecting data, analysing evidence, and interpreting tests

• By replacing all components without testing

• By only using sensory evidence

Which of the following is NOT a method for rectifying faults in propulsion systems?

• Replacing the entire system without diagnosis

• Repairing gearboxes

• Fixing lubrication systems

• Adjusting cooling systems

What type of information is crucial for obtaining and interpreting diagnostic information?

• Colour of the components

• Mechanical condition and efficiency

• Brand of the system

• Age of the system

Which tool is used to measure internal and external dimensions accurately?

• DTI

• Vernier caliper

• Spring gauge

• Dye penetrant

What should be considered when deciding whether to repair or replace a component?

• The colour of the component

• The cost of repair/replacement and availability of parts

• The brand of the component

• The age of the component

What is the purpose of dock side trials in diagnosing propulsion systems?

• To test the system in a controlled environment

• To replace faulty components

• To clean the system

• To paint the system

Which of the following is a method for recording and reporting outcomes after evaluating system performance?

• Verbal communication only

• Manufacturers’ recording sheets

• Personal notes

• Social media posts

What action should be taken if a component is found to be unfit for purpose after evaluation?

• Ignore the issue

• Fit new components

• Paint over the component

• Increase the workload on the component

Which of the following is NOT a factor influencing the decision to repair or replace a component?

• Customer requirements

• Time for repair

• Colour of the component

• Availability of replacement parts

What is the 5s approach used for in restoring the work area?

• To increase the speed of work

• To organise and maintain a clean and safe work environment

• To reduce the number of tools used

• To increase the number of components used
