Train With All Current ATM Systems

The I-SIM® system is a high-fidelity radar simulation system which supports both En Route and terminal operations. The system is delivered with fully functional ERAM and ARTS/STARS display applications.

Tested and Proven

These display applications have been thoroughly tested and evaluated at some of the country’s largest and busiest facilities including SoCal, Phoenix, Cleveland / Detroit, Denver, and Florida Metroplex sites, and recently for the Atlantic Coast Route Program for ZBW, ZDC, ZNY, ZJX, and ZMA.

Used in US Navy

The I-SIM Embedded Trainer application was completed and delivered to the US Navy and deployed on the first ship in 2016. I-SIM is now being deployed to all US Navy aircraft carriers and amphibious assault ships. All Air Traffic Control training on US Navy ships will now be carried out on I-SIM systems.
