BAE Systems CsLEOS For Aircraft (Aug. 20)

JOHNSON CITY, N.Y. --- BAE Systems has introduced a commercial real-time operating system for aircraft and other safety-critical applications.

CsLEOS, a layered, embedded system certifiable to the highest industry reliability standards, draws from decades of experience in design and production of aircraft flight controls.

"As a world leader in fly-by-wire flight controls, BAE Systems has incorporated its background in high-reliability electronics into a system that can be adapted to any number of safety-critical applications," said James Scanlon, president of BAE Systems Controls, which developed the operating system. "CsLEOS is the product of our more than 50 years of evolution in military and commercial flight controls."

CsLEOS is a commercial, off-the-shelf system employing brick-wall time and space partitioning to operate multiple systems independently of each other, such that if one system experiences a failure, the others are unaffected.

The system's ARINC 653-compliant applications programming interface ensures ease of use and certifiability to the highest industry reliability standards for safety-critical use. A flight-worthy version of the system is available now, and a version certifiable to DO-178B, Level A, will be available in the fourth quarter of 2002.

D0-178B, developed by the Radio Technical Commission for Aeronautics, is the international standard for certifying software used in safety-critical airborne systems.

BAE Systems foresees broad potential for CsLEOS on a wide range of military and commercial platforms. The company also plans to market the system for emerging safety- and security-critical applications outside of the aerospace and defense market.

BAE Systems employs nearly 100,000 people including Joint Ventures, and has annual sales of around $18 billion. The company offers a global capability in air, sea, land and space with a world-class prime contracting ability supported by a range of key skills.

BAE Systems designs, manufactures and supports military aircraft, surface ships, submarines, space systems, radar, avionics, communications, electronics, guided weapon systems and a range of other defense products.

BAE Systems North America is a high-technology U.S. company employing more than 22,000 Americans who live and work in 30 states and Washington, D.C. BAE Systems Controls, an operating unit of BAE Systems North America, is a leading supplier and integrator of electronic flight and engine controls for defense and commercial aircraft and launch vehicle applications.

It also provides integrated avionics for aircraft applications and complete unmanned aerial vehicle systems and is a leader in electronic controls for the locomotive industry and the emerging heavy-duty hybrid-electric vehicle market. Controls operates facilities in Johnson City, New York; Santa Monica and Ontario, California; Fort Wayne, Indiana; and Redmond, Washington.
