Fuser Database to TTP Traffic Management Messages

This page documents the mapping between the ATD-2 Fuser Database and the NASA TFDM TTP Traffic Management Messages which are available for consumption via FAA SWIM. This mapping was developed using the TFDM specification and is meant to follow the TFDM specification as closely as possible. Due to constraints of operating in a prototype environment, not all data elements specified by TFDM are published by ATD-2. The schema used is the native TFDM Traffic Management schema. For more information, review the NASA TTP documentation on the NSRR.

To convert data stored in the Fuser DB into TFDM TTP messages, the TFDM SWIM Engine listens for addition, update, and removal events from the TMI Service. Any of these events will trigger the airport data to be transformed to a TFDM message and be published out to FAA SWIM. Populating the elements required by the TFDM specification for TTP Traffic Management Messages, the TFDM SWIM Engine either converts an existing element from the Fuser into the native TFDM schema, or it calculates/derives the element using the logic noted in the "Notes/Calculations" column. The results from this conversion / calculation & derivation are stored in the TTP DB for future reference and debugging.
