Safety-critical RTOS meets FAA requirements
A Green Hills Software product story
Edited by the Electronicstalk editorial team Feb 24, 2003
Green Hills Software has received FAA acceptance of a DO-178B Level A certification package for its Integrity-178B real-time operating system.
Green Hills Software has received FAA acceptance of a DO-178B, Level A, certification package for its Integrity-178B real-time operating system.
The Integrity certification package was delivered to Rockwell Collins for use in Technical Standards Order (TSO) certification for a new avionics system aboard the Sikorsky S-92 helicopter.
FAA audit of the certification package was completed at Green Hills Software's offices in November 2002.
The audit process verified compliance with DO-178B, Level A requirements, a required step for certification of the S-92 aircraft.
The S-92 is Sikorsky's newest medium-lift commercial helicopter.
Featuring a passenger capacity of 19-22, the versatile new helicopter will serve a variety of commercial and international utility needs, including passenger, cargo, aeromedical, search and rescue and resource development support.
Production is already underway with final assembly commencing in March 2003.
Integrity-178B is the core component of Green Hills' solution for safety-critical architectures.
By providing protection in both the time and space domains, Integrity-178B allows applications that have been assigned different DO-178B safety levels to run concurrently on the same processor (ie supports robust partitioning as defined in ARINC 653).
Integrity-178B is derived from Green Hills Software's standard Integrity RTOS product.
Integrity, first released by Green Hills in 1997, is a commercial real time operating system developed for a broad class of mission critical embedded systems.
Allowing multiple software applications to share a common hardware platform, Integrity-178B was designed so that any error in one application cannot prevent another application from continuing to operate.
As such, the Integrity-178B RTOS provides complete time, space, and resource partitioning between applications operating on the same hardware platform.
It provides security and determinism through memory protection and real-time scheduling protection.
