Data Format

One of the CDM group’s greatest successes is the implementation of real-time data exchange between the FAA and its customers. CDM’s success depends upon its participants’ access to real-time, current data to effectively plan daily NAS operations.

Determining the actual data and format to use when exchanging information is a methodical process. The CDM group must first determine which data are crucial to NAS operations and whether or not that data is in an acceptable format to be exchanged over the current CDM communication networks, the CDMNet.

Using the links above, you can see the data items that have been candidates for exchange, the work of the data integration team to format the data candidates, and data exchange formats and protocols.
