What are the upper and lower control limits in trend analysis?

Monitoring aircraft performance has come a long way since the days of the Wright Brothers when performance was judged by fly-to-failure time. Today’s modern aircraft are monitored in a completely different way. In this discussion activity, research aircraft monitoring systems, trend analysis, and trend analysis tools, and discuss the following questions in your initial post:- How can aircraft monitoring systems and trend analysis be used to effectively manage aircraft and component maintenance?- What are the upper and lower control limits in trend analysis?- How do component reliability trends affect the scheduled maintenance program?- What are the advantages and disadvantages associated with managing a trend analysis program?
