Fuser Database to TTP Flight Data Message

This page documents the mapping between the ATD-2 Fuser Database and the NASA TFDM TTP Flight Data 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 Flight Information Exchange Model (FIXM) version 4.0 with NAS Extension. 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 Flight Creation, Flight Update, and Flight Remove events from the Fuser via the Fuser Client API. Any of these events will trigger the flight data to be transformed to a FIXM message and a TTP Flight Data Message will be published out to FAA SWIM. Populating the FIXM elements required by the TFDM specification for TTP Flight Data Messages, the TFDM SWIM Engine either converts an existing element from the Fuser into FIXM, 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.
