Smiths Aerospace Selects Green Hills Software for New Boeing 777 Systems; FAA DO-178B Certified Systems Deployed in New Boeing 777-300ER and Being Retrofit into Earlier 777 Models.

SANTA BARBARA, Calif. -- Green Hills Software, Inc., the technology leader in operating systems and development tools for safe and secure systems, today announced that Smiths Aerospace successfully certified two new systems to the FAA's RCTA/DO-178B safety critical standard using Green Hills Software products.

Smiths Aerospace used Green Hills Software's GMART run-time system and AdaMULTI development environment to develop the software for the Electrical Load Management System (ELMS2) and Fuel Quantity Indicating System (FQIS) for the new Boeing 777-300ER aircraft. The software running in both systems has been certified to the Federal Aviation Administration's (FAA) standard for safety-critical software, RTCA/DO-178B. Both the FAA and European Joint Aviation Authority (JAA) were involved in the certification process.

"Smiths Aerospace selected Green Hills Software's AdaMULTI development environment and GMART run-time system for the ELMS2 and FQIS because these systems met our safety requirements and supported the low power and low cost Freescale ColdFire 5307 processor that we were using," said Dave Bolton, principal software engineer at Smiths Aerospace. "GMART also reduced our development effort because we were able to use Green Hills Software's certification package, including design and verification data, in our FAA certification submittal."

"We are pleased that Smiths Aerospace, like other major avionics manufacturers, is using Green Hills Software's solutions to optimize development of their safety-critical devices," commented Dan O'Dowd, founder and chief executive officer of Green Hills Software. "Avionics manufacturers are increasingly recognizing that they can reduce the time, cost and risk of software development and certification by using our robust and proven off-the-shelf DO-178B solutions. This is why, in addition to the Boeing 777-300ER, Green Hills Software has also been selected for multiple safety-critical systems on both the Boeing 787 and Airbus A380, among others."

About AdaMULTI and GMART

Green Hills Software's AdaMULTI is a complete software development environment for embedded computer-based applications developed using the Ada 95, C, C++ and Embedded C++ (EC++) programming languages. AdaMULTI contains an integrated set of tools that maximize software developers' productivity while enabling them to optimize the reliability, performance and resource requirements of their devices.

Green Hills Software's GMART supports the SPARK safety critical subset of the Ada language. It is ideal for those applications requiring a small fast and deterministic run-time environment. Further SPARK facilitates the development and certification of safety-critical software. GMART has been proven in numerous systems certified to DO-178B, including flight-critical systems that require the most stringent, Level A certification.
