Fuser Database to TTP Flight Delay Message

This page documents the mapping between the ATD-2 Fuser Database and the NASA TFDM TTP Flight Delay 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 Metrics Services listens for Flight Creation, Flight Update, and Flight Remove events from the Fuser via the Fuser Client API prior to sending the data to the TFDM SWIM Engine. The TFMS SWIM Engine transforms the metrics data into a FIXM message and a TTP Flight Delay Message is published out to FAA SWIM. The calculations performed by the TFDM SWIM Engine and Metrics Service are listed in the Notes/Calculations column.
