BAE SYSTEMS CsLEOS' Operating System Chosen For Advanced Flight Control On U.S. AIR FORCE C-17 Transport

29 Jan 2003

The Boeing Company has selected BAE Systems CsLEOS real-time operating system (RTOS) for an advanced flight control system for the U.S. Air Force C-17 Globemaster III transport. The CsLEOS RTOS, a layered, embedded system designed specifically for safety-critical applications, was chosen for the Research Flight Control Computing System (REFLCS).

"We are very pleased that the CsLEOS operating system has been selected for another application on the C-17," said Milan Dedek, product manager for the CsLEOS RTOS. Boeing chose the same operating system for its Redesign Automatic Flight Control System, or RAFCS, an upgrade to the transport's Autopilot Flight Control System.

Boeing Phantom Works is developing REFLCS under a NASA contract that will use a modified C-17 as a flying test bed for study of advanced flight control technologies. REFLCS will augment the transport's Electronic Flight Control System, connecting a new high-performance flight computing system to the existing flight control to allow advanced features to be integrated with minimal risk and cost. The added functionality could include potentially life-saving features such as intelligent flight controls and emergency autopilot capabilities to maintain control of damaged aircraft.

The CsLEOS operating system is the only commercial, off-the-shelf RTOS offered by a safety-critical systems company. Designed from the outset to implement ARINC-653 brick-wall partitioning and to be certifiable to the highest FAA DO-178B safety level, the CsLEOS RTOS ensures that safety-critical functions are protected from other processes running on the same hardware. This structure also makes it possible to add, revise, and test system functions without recertifying the entire application.

The RTOS's ARINC 653-compliant applications programming interface is a true open system that offers users the ability to develop applications software to a standard set of interfaces. This ensures ease of use and the most efficient use of development resources.

The current release of the CsLEOS RTOS is certifiable to DO-178B, Level A, and is available now. (D0-178B, developed by RTCA Inc., a nonprofit company in Washington, D.C., is the international standard for certifying software used in safety-critical airborne systems.)
