What is one safety feature of the traffic alert and collision avoidance system (TCAS)?

The traffic alert and collision avoidance system (TCAS) is specifically designed to enhance safety in aviation by preventing mid-air collisions. One of its key features is that it provides both traffic advisories and resolution advisories. Traffic advisories inform pilots of the presence of nearby aircraft that may pose a collision risk, while resolution advisories suggest specific maneuvers to avoid imminent collisions. This proactive approach is critical in maintaining situational awareness and ensuring the safe operation of aircraft in proximity to each other.

The other options do not accurately reflect the functionality of TCAS. Automating landings in emergencies, monitoring weather conditions, and enhancing cabin pressurization are functions associated with other systems or processes in aviation, but they fall outside the primary role of TCAS. This focus on avoiding collisions distinguishes TCAS as a vital component of aviation safety systems.
