PHOENIX, February 26, 2007 – ACSS, an L-3 Communications & Thales Company, announced today that Skybus Airlines, a new low-cost airline based in Columbus, Ohio, has selected T²CAS and the XS-950 Air Transport Data Link Transponder (ATDL) for installation on their recent order of 65 new Airbus A320 airliners. The A320s are scheduled to begin delivering in the middle of this year.

In addition to the Skybus order, Go Air and Qatar recently selected T²CAS and the XS-950 ATDL for orders of 20 and six new A320s, respectively. This brings the total number of T²CAS customers to almost 60.

T²CAS is a unique safety avionics product that combines terrain awareness warning system (TAWS) with the industry’s leading traffic alert and collision avoidance system, the TCAS 2000.

“We’re pleased with how well the aviation community has responded to our TCAS, TAWS and transponder products as a superior solution for aircraft safety and situational awareness,” said ACSS President Kris Ganase.
