Define "system redundancy" in aircraft design.

In aircraft design, "system redundancy" refers to the implementation of multiple backups for critical systems to enhance safety and reliability. This approach is crucial in aviation, where the failure of key components can have serious consequences. By incorporating redundant systems, such as duplicate hydraulic systems, electrical pathways, or flight control mechanisms, the aircraft can continue to operate safely even if one system fails.

Redundancy is especially important in commercial and transport aircraft, where maintaining control and operational capability is vital for the safety of passengers and crew. The design philosophy emphasizes that even if a primary system fails, the existence of secondary or tertiary systems ensures that the aircraft remains functional and reduces the likelihood of accidents.

This concept also fosters confidence in the aircraft's operational integrity, allowing for safe flight in a variety of conditions. The robust design helps mitigate risks and ensures that the aircraft can perform its intended operations effectively.
