DDC-I's Deos RTOS selected for COMAC C919 commercial airliner program

DDC-I, a leading supplier of software and professional services for mission- and safety-critical applications, announced today that it will supply its DeosTM safety-critical real-time operating system (RTOS) for use in Honeywell's next generation fly-by-wire Flight Control System, which will fly aboard the new Commercial Aircraft Corporation of China, Ltd. (COMAC) C919 commercial airliner.

"We are extremely pleased that Deos has been selected for this key Honeywell flight control program," said Bob Morris, president and CEO of DDC-I. "We look forward to continuing our valued relationship with Honeywell on this very important new avionics program."

Deos is a high performance DO-178B Level A certifiable RTOS that has been used in hundreds of safety-critical avionics applications in dozens of commercial aircraft type certifications and military aircraft types since its initial certification in 1998. The time- and space-partitioned RTOS features deterministic real-time response and employs patented "slack scheduling" to deliver higher CPU utilization than any other certifiable safety-critical COTS RTOS. Deos is the only certifiable time- and space-partitioned COTS RTOS that has been created using RTCA DO-178B Level A processes from the very first day of its product development. It also provides the easiest, lowest cost path of any COTS RTOS to DO-178B Level A certification, the highest level of safety criticality.
