Which of the following describes Back-up Mode?

Back-up Mode is specifically designed to assist pilots in maintaining control of the aircraft during a critical situation, particularly when the Flight Control System is being reset. In this mode, the aircraft remains flyable while the electronic systems are being restored, ensuring that pilots can safely manage the aircraft’s flight characteristics and configuration. This feature is vital in preserving control during potential system failures, allowing for a seamless transition back to normal operational modes once the Flight Control System is fully functional again.

The other options do not accurately represent Back-up Mode: enabling auto land capability indicates an automated feature not relevant in this context, full manual flying abilities would be a characteristic of manual flight modes rather than a backup system, and enhanced maneuverability pertains more to avionics enhancements rather than the specific backup functionalities during a reset of the Flight Control System.
