Green Hills INTEGRITY RTOS Co-Pilots Sikorsky S-92 to Collier Trophy

7/7/2003 - Green Hills Software, Inc. announced that its INTEGRITY-178B real-time operating system (RTOS) was a key ingredient in Sikorsky's win of the Collier Trophy, a benchmark for aviation excellence and achievement.

The Sikorsky S-92, a medium-weight helicopter, was singled out for the Collier award because it incorporates multiple improvements in safety, operating cost and traveling comfort. Featuring a passenger capacity of 19-22, the versatile new helicopter will serve commercial and international utility needs. It's the only helicopter in its class certified to rigorous FAA Part 29 requirements and incorporating the latest specifications for fault tolerance, bird-strike capability and turbine burst protection.

Running on a Motorola PowerPC, INTEGRITY-178B and Green Hills Software's GSTART Ada run-time environment provide the backbone for the Sikorsky helicopter's new Collins Avionics Multi-Function Display system. The system provides the display and integrated management of primary flight data, presentation and management of navigation information for the S-92. The system also provides a digital map, weather radar, terrain information and engine instruments.

Rockwell Collins also used INTEGRITY-178B and GSTART to achieve DO-178B Level A certification of the Avionics Multi-Function Display system aboard the S-92.

INTEGRITY-178B is an ARINC-653 compliant, hard real-time RTOS optimized for safety-critical and mission-critical applications that require the utmost security and fast, predictable response. Using hardware memory protection and an advanced two-level partition scheduler, INTEGRITY-178B provides complete time, space, and resource partitioning between applications operating on the same hardware platform. This partitioning effectively builds a firewall between applications and the kernel, preventing errors in one application from corrupting other applications or the kernel.

INTEGRITY-178B is tightly integrated with Green Hills Software's AdaMULTI Integrated Development Environment.
