DO-219 provides the Minimum Operational Performance Standards (MOPS) for data link communications for Air Traffic Control - the structure and format of the messages themselves. The CNS/ATM version of DO-178B is DO-278 (currently being amended to DO-278A) just deals with the software aspects for equipment being developed for use in the CNS/ATM domain.

Life sometimes turns on a dime. Especially when you are actively looking out for a change. I now work at HCL Technologies. And all I am looking for is to make a difference. By the way, the blog contents remain my own. It does not reflect the official position of HCL.
