Rockwell Collins' CISS-2100 Configurable Integrated Surveillance System is a highly integrated system that significantly enhances safety of flight, lowers airline operating costs, and enables seamless integration of future surveillance and hazard detection functions. The system combines weather detection, traffic alert and collision avoidance, Mode S surveillance and terrain awareness and warning functions into a single system.

The CISS-2100 uses 40 percent fewer parts than traditional federated aircraft surveillance systems. This results in reduced weight, volume and power consumption all more important in today's airline operating environment. It also allows for a reduction of airline spares inventories by replacing four LRU's with one. Simultaneously, the integrated system offers the most advanced weather, traffic and terrain surveillance functions available.

The CISS-2100 also provides the platform for Rockwell Collins' next generation cooperative surveillance operations and applications for both airspace users and ground-based system managers. ADS-B, TIS-B, traffic computing functions, and decision support applications are all integrated into the configurable system.
