In a fail operational autopilot landing system, what ensures continued auto landing if one system fails?

In a fail operational autopilot landing system, the primary goal is to ensure that the aircraft can continue its landing procedure even if one of the systems fails. A triplex system is designed with three independent systems that work simultaneously, allowing for redundancy. In this setup, if one system fails, the remaining two systems still function together, providing the necessary control and data needed to accomplish a safe landing.

This triplex architecture enhances safety by allowing continual operation despite a single point of failure. The data from the two operational systems are cross-verified to ensure accuracy and reliability, making it a robust choice for critical operations like auto landing. This redundancy is vital in aviation systems as it significantly minimizes the risk of failure during crucial phases of flight, such as landing, where safety is paramount.

The other options do not provide the same level of continuous operation in the case of a system failure. While a duplex system might provide some backup, it does not offer the same level of reliability as a triplex system and risks complete failure if one system fails. Advanced AI management could improve system efficiencies and predictive maintenance but would not inherently guarantee continued operation if a failure occurs. Finally, a manual override by the pilot is a fail-safe measure rather than a solution that allows for
