NORTHWEST AIRLINES LAUNCHES T²CAS™

Northwest Selects ACSS’ Technically Superior TAWS Solution for A330s

PHOENIX, AZ, Feb. 27, 2002 – ACSS, an L-3 Communications & Thales Company, announces that Northwest Airlines has selected T2CAS? for its fleet of Airbus A330 aircraft with options for the rest of their fleet. T2CAS is a unique safety avionics product that combines aircraft performance-based TAWS (Terrain Awareness Warning System) with the industry’s leading traffic alert and collision warning system, the TCAS 2000.

“We’re thrilled that Northwest Airlines has selected T2CAS,” said Joe Hoffman, president of ACSS. “Our relationship with Northwest Airlines dates back to 1992 when they became a launch customer for our first-generation TCAS II. Northwest Airlines has now selected a safety avionics solution that not only delivers the industry’s best TCAS, but also raises the bar for TAWS technology.”

Unlike other TAWS products, T2CAS is a true terrain avoidance product that bases its operator alerts on an aircraft’s actual ability to climb at a given moment – not based on predetermined computations. T2CAS also reduces weight, power consumption, space requirements, and wiring because it’s a combined TCAS and TAWS solution. Northwest’s fleet is already equipped with TCAS 2000, so they will be able to simply swap out the TCAS box for the new T2CAS box using the existing power supply and wiring.

The TCAS 2000 became the industries’ first second-generation TCAS II product when it was launched in 1997. Since then, ACSS has delivered more than 5,000 units, making it best selling second-generation TCAS II in the industry. The TCAS 2000 has earned acclaim throughout aviation for its ability to track aircraft beyond 100 nautical miles and its built-in growth capability for enhancements such as TAWS and Automatic Dependence Surveillance-Broadcast (ADS-B).

ACSS announced the development of T2CAS? (Traffic and Terrain Collision Avoidance System) at last year’s Paris Air Show. Certification is anticipated at the end of this year.

ACSS (Aviation Communication & Surveillance Systems), an L-3 Communications & Thales Company, is a leader in safety avionics systems. ACSS products include the TCAS 2000 and TCAS 1500 traffic alert and collision avoidance systems, a family of Mode S transponders, the T²CAS™, a combined traffic and terrain collision avoidance system, and MASS, an enhanced TCAS system for military operations.
