Question
in order to increase the safey of its fleet, Safety-First Airlines (SFA) wants to install a redundant system to ensure against instrument malfunction. The original system consist of five components in series, with reliabilities of .995, .995, .999, .998, and .980. The airline has the choice of adding an identical backup to each component that will activate automatically if that component fails, or completely separate backup system that is identical to the primary system. This separate system is activated via an automatic swithch with a reliability of .995. Which option would you recommend SFA install in its planes?Explanation / Answer
The first one, because this will be activated automatically, and will analyze each one component of the system, it will be more easy find the fails if someone did it. However it is always good to make a deep analysis of the situation, to give a more accurate recommendation regarding the case. It is very important to know that the functionality of an aircraft is directly related to its maintenance process regardless of the design process of this or security systems to carry it, because during the course of its operating life the aircraft will be subject to some conditions that may generate changes in its operation. We both know that the fault generated in a system can lead to several problems for the company such as the loss of the system to perform all required functions so as to generate the loss of system capacity to meet all your requirements. I recommend that you apply Reliability Centered Maintenance or RCM (we need more time and information to do it), which analyzes the operational reliability of the components are operating within given conditions, so you can set different tasks and tasks maintenance depending on the level of criticality of failure presented and the effects of component failure within the system involving the safety of the crew, the environment and fleet operations.
I hope this can help you well! :)
