How does the ERJ's autopilot system enhance safety during long flights?

The autopilot system in the ERJ plays a crucial role in enhancing safety during long flights primarily by reducing pilot workload. This reduction allows pilots to focus more effectively on monitoring aircraft systems and managing the overall flight environment, rather than being fully engaged with manual flying tasks for extended periods. With the autopilot handling routine flying tasks, pilots can maintain situational awareness, perform system checks, and respond to any unexpected situations more efficiently.

By lessening the cognitive and physical demands placed on the pilots, the autopilot system helps to mitigate fatigue, which can be a significant factor during long-haul flights. This improved ability to monitor and react to potential issues increases overall safety, as pilots are better equipped to manage the complexities of flight systems and address any problems that may arise.

The other options do not accurately reflect the primary functions of the autopilot system. For instance, while the autopilot can control the aircraft in certain phases of flight, it does not take complete control throughout the entire flight in a way that would negate the pilots' roles. Similarly, the autopilot is not responsible for adjusting fuel consumption or providing real-time video feeds from outside the aircraft, as those functionalities are outside the scope of typical autopilot operations.
