BAE SYSTEMS REAL-TIME OPERATING SYSTEM SELECTED FOR C-17 GLOBEMASTER III FLIGHT CONTROL UPGRADE

BAE SYSTEMS open-architecture real-time operating system has been selected for use on a major upgrade to the flight control system on the Boeing C-17 Globemaster III transport. The company's CsLEOSâ„¢ RTOS will underpin the C-17's Modernized Flight Control Computer and Spoiler Control Electronic Flap Computer programmes - two efforts Boeing Integrated Defense Systems recently issued to BAE SYSTEMS Platform Solutions under separate awards.

Use of the CsLEOSâ„¢ RTOS, along with the artefacts in the available certification package, will allow for the flight control suite to be DO-178B Level A-qualified in support of Global Air Traffic Management (GATM) system requirements. GATM, established by the Federal Aviation Administration in co-operation with the International Civil Aviation Organization, aims to enhance safety in increasingly crowded world-wide air space.

The embedded, open-architecture operating system, which uses "brick-wall� time and memory partitioning in compliance with the ARINC 653 specification, also reduces life-cycle costs by permitting upgrades to be made without recertification of the entire application.

"Boeing and BAE SYSTEMS have enjoyed a long relationship on the C-17, with our work on the flight control dating to 1989, and have grown to become the largest avionics supplier on the aircraft,� said James Scanlon, president of BAE SYSTEMS Platform Solutions. "We are excited about incorporating our real-time operating system into this next phase of the flight control programme.� The C-17 is operated by the U.S. Air Force and the U.K Royal Air Force.

The CsLEOSâ„¢ operating system is the only commercial, off-the-shelf RTOS offered by a safety-critical systems company. Its brick-wall partitioning allows multiple applications to run on the same system without interfering with each other, ensuring that safety-critical functions are protected from other processes running on the same hardware. The unique design of the CsLEOSâ„¢ RTOS provides capabilities that both enhance performance and reduce development efforts:

Multiple scheduling modes — a flexible feature that increases performance by allowing users to switch between different schedule profiles in real time, making it possible to change the schedule of existing applications and/or add new applications on the fly.

Separate loadable images that allow each application to be built and downloaded as a separate program, reducing life-cycle costs and minimising the need for regression testing.

A DO-178B, Level A-certifiable version of the CsLEOSâ„¢ RTOS, complete with documentation artefacts to support system certification, is available now. (D0-178B, developed by RTCA Inc., a non-profit company in Washington, D.C., is the international standard for certifying software used in safety-critical airborne systems.)
