PHOENIX, May 22, 2007 – ACSS, an L-3 Communications & Thales Company, announced today that the Hawker Beechcraft Corporation (HBC), formerly known as the Raytheon Aircraft Company, has selected ACSS’s advanced terrain awareness warning system (TAWS) solution with the installation of TAWS+ on the King Air C90GTi aircraft.

“Hawker Beechcraft has set the standard for general and business aviation with unsurpassed performance, quality, value and technological innovation,” said ACSS President Kris Ganase. “With our TAWS products on board, Hawker Beechcraft customers will experience the enhanced safety of the most advanced TAWS product available. We’re pleased to be HBC’s TAWS supplier on their newest King Air.”

ACSS’s TAWS+ and TAWS+performance are stand-alone, Class A TAWS for passenger props, jets and military aircraft with over 2,000 units sold or on order as a stand-alone product or as part of ACSS’s T²CAS product, an integrated TCAS and TAWS in a single line-replaceable unit (LRU). ACSS’s TAWS+performance is the industry’s only aircraft performance-based TAWS available in the marketplace. The advanced safety capabilities 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) enables Modes 1-5 and provides unique predictive warnings and cockpit displays.

Among the patented features is a Terrain Advisory Line (TAL) that indicates where the terrain is 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.

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.
