DO-200A is the standard used to develop, support implementation, and assess change of data processing quality assurance and data quality management – DO-200B is a modest upgrade to DO-200A.

Implementing a process complying with requirements, RTCA’s DO-200A provides a level of assurance that the data quality is maintained throughout all phases of the data handling process within an organization.

DO-200B has an increased focus on the overall aeronautical data (DO-200A was somewhat more “navigation” oriented), data security, aeronautical data chain, increased scope/definition of tool qualification and DO-330, and expanded definitions/clarity. DO-200B provides the “minimum” standards.

DO-200B is part of the overall Aviation Development Ecosystem, which includes airborne and ground-based software/systems combined with formalized Safety processes. 

DO-200B requires planning, data requirements, processing requirements and proof of related processes; these items must then be validated and verified throughout the data-chain, beginning with data receipt and ending with data transmission. Both data Supplier and User share responsibility for ensuring data integrity. 

DO-200A concerns the entire chain of aeronautical data usage, from inception, analysis, revision, usage and feedback. Both  DO-200A and DO-200B provide clear but flexible guidance on ensuring aeronautical data sanctity.

Want to learn more? Tonex offers DO-200A Training | DO-200B Processing Aeronautical Data training, a 2-day course that  provides participants with the principals, methods and requirements for avionics databases. 

Participants will learn the differences and similarities of DO-200A and DO-178 databases and the techniques are used during the development of each. You also will become familiar with the ecosystem modification of DO-200A avionics data, from the conceptual stage all the way to the end-user.
