scope:

This document addresses the alteration of data and guides entities in the processing, disposition, and/or use of altered aeronautical data. These entities may be any of the stakeholders involved in the aeronautical data chain and listed in Table 1.1. This document does not establish requirements above what is required in RTCA DO-200B/EUROCAE ED-76A, nor is it prescriptive in how existing aeronautical data chains process data. Alteration is separate from assembling, translating, selecting, or formatting of data. Withholding data found to be in error is not considered alteration. Consequently, this document does not apply to data changes which preserve the meaning of the data.

While this document refers to origination in order to differentiate it from alteration, it does not provide any additional guidance for origination, given that it is deemed sufficiently covered by DO-200B/ED-76A.
