What are 'air traffic collision avoidance' systems designed to do?

The role of air traffic collision avoidance systems is primarily to assist pilots in preventing potential collisions with other aircraft during flight. These systems utilize various technologies to monitor the surrounding airspace, providing real-time data and alerts to pilots when the risk of a collision is detected. This is vital in maintaining safety in the air, especially in crowded airspace. By giving pilots crucial information about the position, altitude, and trajectory of nearby aircraft, the system enhances situational awareness and supports informed decision-making, allowing for timely maneuvers to avoid dangerous situations.

In contrast to other options, enhancing fuel efficiency, automating flight processes, or improving passenger comfort does not directly relate to the main function of collision avoidance systems, which is focused solely on preventing accidents in the air.
