(001) Under the concept of two-level maintenace, which is left out?
- A.
Depot
- B.
Operational
- C.
Intermediate
Correct Answer
C. IntermediateExplanation
In the concept of two-level maintenance, the intermediate level is left out. Two-level maintenance refers to a maintenance system that is divided into two levels: depot level and operational level. The depot level involves extensive repairs and overhauls of equipment, typically performed at centralized facilities. The operational level, on the other hand, focuses on routine maintenance tasks that can be performed by the operators or lower-level maintenance personnel in the field. The intermediate level, which would fall between depot and operational, is not included in this concept.Rate this question:
