Benefits The main goal of fault detection and isolation is to effectively detect faults and accurately isolate them to a failed component in the shortest time possible. This capability leads to reduction in diagnostic time or downtime in general and, therefore, increased system availability. A good inherent diagnostic of a system also enhances the crewmembers' confidence in operating the system, the main driver of mission success. Effective FDIR can keep a difficult to maintain system up and running where normal methods would lead to system downtime. FDIR is especially beneficial to an on-orbit system where maintenance may be impossible.
