PHOENIX, June 18, 2007 – ACSS, an L-3 Communications & Thales Company, has signed an agreement with Airbus to study the certification of  its integrated TCAS, TAWS and Mode S Transponder product –T³CAS – on the A320 and on the A330/A340 aircraft families.

T3CAS features a traffic alert and collision avoidance system (TCAS), Class A terrain awareness warning system (TAWS) and Mode S Transponder in a single line-replaceable unit (LRU) with a 6- MCU form factor. As stand-alone products, ACSS has distinguished itself in each of these product categories.

T3CAS will deliver lower acquisition and ownership costs, less weight and volume, and reduced wiring with improved power efficiency. The integrated platform offers capabilities not currently available in any other system, and will form the baseline for Airbus to host future ADS-B-In (automatic dependent surveillance-broadcast) functionality on their aircraft, such as In-Trail Procedures (ITP) and Air Traffic Situational Awareness (ATSAW), which will feature ACSS’s expertise in advanced ADS-B functionality.

“This is a tremendous vote of confidence for ACSS and the work we are doing to enhance aviation safety,” said ACSS President Kris Ganase. “By providing better situational awareness to pilots and improving operational efficiency for operators with our advanced ADS-B-based functionality, the T3CAS will put Airbus at the forefront of ADS-B implementation. This has proven to provide significant environmental gains through reductions in emissions and noise.”

Aviation Communication & Surveillance Systems (ACSS), an L-3 Communications & Thales Company, is a leader in safety avionics systems that increase safety, situational awareness and efficiency for aircraft operators. Based in Phoenix, its products include the TCAS 3000 and TCAS 2000 traffic alert and collision avoidance systems; MASS™, an enhanced TCAS for military operations; a family of Mode S transponders; the T²CAS®, a combined traffic and terrain collision avoidance system; TAWS+, a stand-alone terrain awareness warning system; and the Dlink+ communications management unit. The ACSS portfolio also includes a suite of automatic dependent surveillance-broadcast solutions for pilots operating in the airport vicinity called SafeRoute™.
