ACSS, an L-3 Communications and Thales Company, announced an agreement with Airbus to certify its T3CAS product on all Airbus single aisle (A318/319/320/321) and long range (A330/A340, including A340-500/600) aircraft. T3CAS is a system combining traffic alert collision avoidance (TCAS) with terrain awareness warning (TAWS) capability and a Mode S Transponder. It features a TCAS II, Class A TAWS and Mode S Transponder in a single line-replaceable unit. ACSS, based in Phoenix, said the integrated platform for Airbus will offer ADS-B In capabilities. The new transponder will be a software update to ACSS transponders currently fitted on Airbus fleets.
