How many segments are there in each TCAS antenna?

The correct answer is based on the design and functionality of the Traffic Alert and Collision Avoidance System (TCAS) antennas. Each TCAS antenna consists of four segments, each covering a 90-degree field of view. This configuration allows the system to effectively monitor the airspace around the aircraft in all directions.

The division of the antenna into four 90-degree segments enables an accurate and nuanced detection of surrounding aircraft, enhancing situational awareness and collision avoidance capabilities. By analyzing data from these segments, the TCAS can determine the relative positions and movements of nearby aircraft, and then provide necessary alerts to the pilots.

Understanding the structure of the TCAS antenna is crucial for comprehending how the system generates and utilizes its data for safety measures in aviation.
