Key Takeaways:

Modern collision-avoidance technologies, including ADS-B, TCAS, TAS, and TIS, are widely used in aviation.
ADS-B significantly expands traffic-alerting capabilities to the airport surface and provides pilots with a tactical view of nearby traffic.
Traffic-alerting systems generally employ similar symbology to display targets, indicating relative bearing, distance, and altitude.
Specialized TAS products for General Aviation (GA) aircraft are available, with examples like Avidyne's systems ranging from $8,500 to $22,000.

A closer look at the latest in collision-avoidance technology.

ADS-B — ADS-B is expanding traffic-alerting capability to the airport surface. Here, technology from ACSS highlights the departure runway and landing traffic in yellow.

Rockwell Collins Traffic-Alert Technology — The latest traffic-alert gear from Rockwell Collins combines a dedicated TCAS II system with ADS-B “Out” technology for unparalled collision protection.

Collision Avoidance System — Whether you fly with TIS, TAS or TCAS, traffic-alerting technologies use similar symbology, displaying targets based on relative bearing, distance and altitude.

Avidyne TAS — TAS products for GA aircraft sell for between $8,500 and $22,000. Avidyne’s technology uses antennas that mount to the top and bottom of the fuselage.

ADS-B — One of the key benefits of ADS-B is in giving pilots a tactical view of nearby traffic. UPS is using the technology to fly more airplanes into its busy Louisville hub.
