Flight navigation system nears acceptance
Raytheon is preparing to begin FAA acceptance testing of its Wide Area Augmentation System (WAAS)
WAAS uses Wind River's Tornado for DO-178B development environment, which includes the VxWorks real-time operating system (RTOS). Following FAA acceptance Tornado for DO-178B and the rest of the WAAS system will be certified for commercial flight navigation use. The FAA tests will ensure WAAS is compliant with its system and software requirements as well as with the DO-178B standard - an internationally recognised standard created by the non-profit organisation, Radio Technical Commission for Aeronautics.

The standard is comprised of 66 software certification safety objectives for airborne systems and equipment.
Raytheon designed WAAS in accordance with the FAA's stringent safety standards, while reducing risk and saving on development costs by using commercial off-the-shelf (COTS) certifiable software from Wind River.
The DO-178B standard has five certification levels that range from most critical for assuring aircraft safety (Level A) to least critical (Level E).
While WAAS' most stringent safety requirements are only Level B, Wind River's Tornado development environment is designed to address DO-178B Level A requirements, as well as the requirements for lower levels.
"Wind River is proud to offer a certifiable DO-178B COTS solution so Raytheon can improve the nation's flight navigation systems with WAAS", said John Fogelin, CTO, vice president and general, Wind River's Aerospace and Defense Business Unit.
"Wind River has made a big investment in delivering a certifiable kernel for use in avionic systems.
We have designed our kernel to meet the 66 objectives set forth in the DO-178B standard, and have created a development environment our customers can use as a platform to create their mission critical devices".
