Redundancy development situations

Dear, developers… It is essential of redundancy system in aircraft system. I will appreciate if somebody guide me where can I find redundancy development situations in each item? For example, redundancy of flight computer, each sensor, communication system or others?

Not an easy topic, and not something supported out of the box.

Yeah… Surely hard job… but need to go one this way for safety. I think it should be a essential category for future systems.
