Product information
The Deos Real-Time Operating System is the most deployed COTS RTOS in avionics history.
Deos™ was built from the ground up with plans and procedures created to the guidance of DO-178DAL A starting with its requirements for its first line of code. In fact, Deos was the first time and space partitioned RTOS certified for flight on aircraft by the FAA, EASA, and most other certification authorities world-wide. It is the overwhelming dominate COTS RTOS for commercial aircraft avionics.
If you need safety-critical performance, the choice is DDC-I. Deos is:
