Pratt & Whitney Certifies Engine to DO-178B Level-A With Aonix® ObjectAda®/RAVEN
Jan 24, 2002 - 20:50 PM
The Pratt & Whitney certification was achieved at software Level-A of RTCA’s DO-178B, Software Considerations in Airborne Systems and Equipment Certification. Certification to DO-178B requires that all COTS software included in the product be certified to the same standard as the core product. ObjectAda/RAVEN meets this standard for Level-A systems.
Pratt & Whitney incorporated the full suite of lifecycle artifacts provided by Aonix within the overall engine-system software documentation set approved for certification by the Federal Aviation Administration. By utilizing the ObjectAda/RAVEN product and associated documentation, Pratt & Whitney was able to focus development efforts on its core competency of engine-system software, while ensuring that the run-time system portion of the product was developed and verified by experts in that domain. This approach reduced the schedule and technical risks associated with the program while also reducing development cost.
“Pratt & Whitney selected the ObjectAda/RAVEN product for use on the PW6000 in 1998 following an extensive evaluation. Aonix was selected for a variety of reasons including the usability of the tool set and the technical support that they were able to provide,” states Bret Lynch, Manager, Real Time and Embedded Software for Pratt & Whitney. “The main discriminator, however, was the safety-critical domain experience of the company and their ability to meet the standards required for incorporation into a DO-178B Level-A software system.”
Aonix is the leading supplier of certified (i.e., certifiable) run-time systems for the Ada 83 language and offers the only certified Ada 95 run-time system. ObjectAda/RAVEN is certified to the highest certification levels and meets the DO-178B Level-A required by the FAA for airborne systems.
