PHOENIX, March 9, 2003 – ACSS, an L-3 Communications & Thales Company, is pleased to announce that Air Wisconsin has selected T²CAS™ (Terrain and Traffic Collision Avoidance System) for installation on its fleet of BAe 146 aircraft. T²CAS is a unique safety avionics product that combines aircraft performance-based terrain awareness warning system (TAWS) with the industry’s leading traffic alert and collision avoidance system, the TCAS 2000. Air Wisconsin joins a growing list of T²CAS customers that include major and regional airlines, business jets and military programs.

In addition to T²CAS, Air Wisconsin has selected ACSS’s new datalink solution, the Dlink+. Dlink+ is a state of the art, high performance flight deck data communication system that provides access to ACARS (aircraft communications and reporting system) and other services. Dlink+ integrates a communications management unit, VDL Mode 2 digital radio, and control display unit, offering operators a strong combination of functionality and value in a small package. Air Wisconsin selected Dlink+ for their BAe 146 fleet and its Bombardier CRJs.

“We’re thrilled that Air Wisconsin has selected T²CAS and the higher level of safety and situational awareness it provides,” said Joe Hoffman, president of ACSS. “Combined with Dlink+, Air Wisconsin has upgraded its fleet with important safety and situational awareness equipment.”

T²CAS includes the TCAS 2000, ACSS’s second generation TCAS II currently flying on more than 7,000 corporate, regional, air transport and military aircraft. Along with optional GPS, T²CAS provides a powerful combination of functionalities that result in space, wiring, weight and power savings. T²CAS is a performance-based system that can be applied to any business, regional, air transport or military aircraft to avoid Controlled Flight Into Terrain (CFIT), which gives operators more time to clear terrain and traffic with an increased margin to maneuver and reduce nuisance alerts. The Ground Collision Avoidance Module (GCAM) within T²CAS enables Modes 1-5 and provides unique predictive warnings and cockpit displays.

Among the patented features is a Terrain Advisory Line that indicates where a Caution Alert would be generated should the aircraft continue on its flight path. The length and duration of the alert line mirrors the cautionary terrain segment within 30 degrees either side of the aircraft flight path, out to four minutes in front of the aircraft. When the GCAM detects that the aircraft does not have sufficient climb capability to clear the terrain by a standard vertical recovery maneuver, it generates a unique identifiable “Avoid Terrain” aural-visual alert.

ACSS (Aviation Communication & Surveillance Systems), an L-3 Communications & Thales Company, is a leader in safety avionics systems.
