The primary reference that should be consulted to determine the existence of or need for a data standard is the FAA Data Registry (FDR). The FDR is a tool for recording, publishing, and maintaining metadata about application-independent data standards. The FDR Portal is available on the Internet at http://fdr.faa.gov/. It provides information about the precise meaning of data, and it provides a place to capture information during the development of data standards. It is the authoritative source for FAA data standards. The first activity is to compare the data element of interest with metadata of existing data standards in the FDR. The interface requirements developer should prepare for this activity by compiling the following information for the data element of interest:
• Definition or description of the data element
• Common name of the data element
• Context in which the data element is applicable or has meaning
• Range of values that the data element may assume

Standardization is an enabling strategy, which can help developing organizations and system owners to achieve a common goal of providing the NAS with equipment that is interoperable, reliable, and technologically superior. Since the FAA usually retains existing systems beyond their planned service life, affordable and rapid technology insertion depends, in part, on FAA's ability to define standard solutions across systems based on performance and interface requirements. Adoption of application-independent data standards will help the FAA integrate and share NAS information across multiple systems, programs, government agencies, industry, and the international community.
This Standard describes the detailed NAS data specifications for use in defining all data interfaces controlled by the NAS Configuration Control Board, that is, interfaces specified in an Interface Requirements Document (IRD) – or, where there is no parent IRD for data specifications, the Interface Control Document (ICD) – that becomes a NAS Configuration Item. This Standard also applies to data required for two or more NAS systems, regardless of the storage or transmission media used; e.g., manually-transmitted adaptation data that is not specified in an IRD or ICD.
