Which system or mechanism is responsible for ADS reversion in the Embraer Regional Jet?

The Auxiliary Data Systems are responsible for ADS (Automatic Dependent Surveillance) reversion in the Embraer Regional Jet. In aviation systems, ADS provides crucial surveillance data to ensure safe operations, especially when primary systems fail or are unable to perform their designated functions. The Auxiliary Data Systems act as a backup, ensuring that essential data continues to be available for the flight crew, regardless of potential failures in primary systems.

This mechanism plays a critical role in maintaining situational awareness and operational safety. By reverting to Auxiliary Data Systems when needed, the aircraft can continue to operate smoothly and effectively, providing the necessary information required for navigation and surveillance.

The other options pertain to different systems within the aircraft. The Primary Flight Display provides critical flight information but does not handle the reversion of ADS. The Flight Control Computer is focused on managing the flight control laws and aircraft stability. The Auto-throttle System manages engine power but is not involved with the surveillance data integrity or reversion process.
