When in normal mode, traffic will display on the TCAS when it is how many feet above/below the aircraft?

In normal mode, the Traffic Collision Avoidance System (TCAS) displays traffic when it is within 2700 feet vertically above or below the aircraft. This vertical range allows pilots to be aware of potential traffic that could pose a collision risk, giving them critical situational awareness regarding nearby aircraft. The TCAS is designed to alert pilots to traffic situations to ensure safety in flight, and the 2700 feet threshold is established to provide adequate reaction time while also filtering out less relevant traffic that might be too far away to impact flight safety.
