Honeywell offers TCAS systems for most business aviation, air transport and regional aircraft.

Throughout the 1960s and 1970s, Honeywell led the way in aircraft collision avoidance, developing prototype systems for the U.S. Army and FAA. In the 1980s, when TCAS II was mandated for the airlines, we were ready with patented hardware that surpassed FAA requirements for signal processing and accuracy. Today, Honeywell's family of TCAS products serves as the foundation of the future free flight environment.

Backed by Honeywell's worldwide network of support centers, our family of TCAS products offers you an extra measure of confidence wherever you fly. With our membership in the numerous industry committees that define new operating standards, you can be sure Honeywell systems will continue to meet all new performance directives, from increases in range to a greater capacity to identify potential conflicts.
