Meggitt Control Systems Builds Cabin Air Control System With Green Hills Software

SANTA BARBARA, CA, May 19 (MARKET WIRE) --
Green Hills Software, Inc., the world leader in certified safe and secure
real-time operating systems (RTOS) and device software optimization
(DSO), today announced that Meggitt Control Systems is using Green Hills
Software's comprehensive software development solutions to build a cabin
air temperature control system for private cabin-class jets. The Meggitt
Control Systems' bleed air system will be used on the Embraer Legacy 500
midsize and 450 midlight business jets.

"The Green Hills MULTI(R) integrated development environment (IDE)
reduced our project risk during the start-up phase and continues to help
us achieve productivity through the robustness and quality of the tools
compared to other products that crash or exhibit erroneous behavior,"
said Adam Saenz, software engineer, Meggitt Control Systems. "MULTI is
easy to use and allows me to quickly launch views that help me debug
programs efficiently."

Meggitt Control Systems chose Green Hills Software because of its single
vendor support for the MULTI compiler, debugger, Green Hills Probe JTAG
and other tools. The MULTI IDE is pre-configured to support the Freescale
55xx target, assisting with ease in processor bring-up and resulting in
savings in schedule time and expenses.

About the Meggitt Control Systems Air Cabin Control System

The Meggitt Control Systems Pneumatic System will actively control a
series of smart and shut-off valves to supply air from the aircraft jet
engines to several systems aboard the aircraft. These systems include
cockpit, cargo and cabin environmental and pressurization systems. Bleed
air from the jet engines is also supplied to the aircraft's anti-icing
system. Meggitt's Control System will be certified to DO-178B Level A
standards, underscoring the critical nature of the Pneumatic System.
