RTOS to fly in F-35 cockpit display

May 19, 2006 (by Jeff Hollenbeck) - L-3 Communications Display Systems has chosen the LynxOS-178 real-time operating system (RTOS) to power a portion of the panoramic cockpit display (PCD) subsystem for the Lockheed Martin F-35 Joint Strike Fighter (JSF) aircraft.

This display system delivers information for all the major functions of the F-35, including flight and sensor displays, communication, radio and navigation systems as well as an identification system which gives the pilot total situational awareness. The key factors in L-3 Display System's choice of LynuxWorks' RTOS, which is DO-178B certifiable, were its adherence to open standards, its Linux compatibility, the interoperability benefits of a Posix API and support for the ARINC-653 specification.

In addition, LynuxWorks will deliver an embedded software product with a complete set of artifacts, along with world-class engineering services.

Lastly, the LynxOS-178 RTOS was recently awarded the first Reusable Software Component letter from the Federal Aviation Administration.

This certification helps further reduce time to market and risk for customers using LynuxWorks' RTOS.

The F-35 is a next-generation, supersonic stealth aircraft designed to replace a wide array of existing fighters.

'We chose LynuxWorks' operating system because the company offered a very complete RTOS and artifact package, along with support services and business models that were unmatched by other vendors', said Bob McGill, President of L-3 Displays Group.

'In the military and defence market, we are required to work with stable vendors that have a solid and complete track record'.

'And, with LynuxWorks, we were able to capitalise on their product's strengths and deliver a solution that will exceed our customers' expectations with respect to performance and safety'.

In an industry where safety, time and cost are essential factors, L-3 Display Systems is leveraging a series of product features and services from LynuxWorks' LynxOS-178, which includes an RTOS that is designed specifically to fulfil the stringent needs of multithread and multiprocess applications in safety-critical systems.

Based on open standards, the LynxOS-178 RTOS provides security through virtual machine brick-wall partitions that make it impossible for system events in one partition of the RTOS to interfere with events in another.

It's as if each partition were its own separate computer providing the highest levels of robustness.

'We are thrilled to be working with L-3 Display Systems on this very important programme and acknowledge this as a huge validation of our LynxOS-178 product family', said Joe Wlad, Director of Product Management and DER with LynuxWorks.

'Our technical leadership and progressive business models are very attractive to military avionics suppliers who are transitioning from proprietary operating systems to open standard-based solutions'.
