Response:
Question 73
What is meant by "derating"?
I. The technique of using a part, component, or equipment under stress conditions considerably below rated values, to achieve a "reliability margin" in design.
II. The technique of using a part, component, or equipment under normal conditions to achieve a reliable product design.
III. The technique of using a part, component, or equipment below stress conditions to achieve a reliable product design.
Response:
Question 74
A high incidence of failures has developed during aircraft acceptance testing. The identified failure is that an instrument panel light has malfunctioned on 6 of the last 10 aircraft tested.
This problem needs to be investigated and a Failure Reporting and Corrective Action System (FRACAS) needs to be completed without stopping aircraft production.
If the cause of the failure is determined to be a faulty subassembly manufactured only by a single supplier, and this situation is threatening to shut down aircraft production, the next step should be to Response:
Question 75
Which process has as its principle parts
- Defining the system.
- Establishing the reliability model.
- Assigning failure rates to the equipment involved.
- Computing the reliability for each function and for the system.
