Departure Approval Request Compliance Effects on Overhead Stream Insertion

Integrated Arrival-Departure-Surface (IADS) air traffic management relies on information sharing and integration between automation systems for efficiency, predictability, and throughput improvements throughout the National Airspace System (NAS). The NASA Airspace Technology Demonstration 2 (ATD-2) project supports this effort by integrating SWIM (System Wide Information Management) information and evaluating and refining potential TFDM (Terminal Flight Data Manager) functionality in a surface traffic management system fielded at Charlotte-Douglas International Airport (CLT). Among the IADS areas under study during ATD-2 is the use of electronically negotiated departure times for efficiently inserting flights into overhead traffic streams. Stream-insertion accuracy is important for reducing excessive vectoring that negatively impacts the NAS by increasing controller workload along with aircraft fuel burn and emissions. Departure-time approval requests (APREQs) provide center-approved departure times to allow for smooth stream insertion. In this presentation, TBFM (Time-Based Flow Management) and ATD-2 flight summary data are used to empirically show that APREQ compliance leads to improved stream insertion

Airspace Technology Demonstration 2 (ATD-2): CDM CAT NTML Lessons Learned

This presentation conveys lessons learned about data, data sources, and TMIs from the ATD-2 field demonstration

Evolving Operational Role (ATC and Operator) with TFDM in the 3T Environment

As the surface system is deployed across the NAS and fully integrated with existing FAA decision support, the roles of both ATC and Operators are expected to change. This will discuss first hand examples of this evolution as experienced at CLT

Understand and Process ATC Restrictions in the National Airspace System: Part 2

Continues Part 1 discussion by using ATD-2 technology as a stand-in for expected TMI entries in the future TFDM system. This topic will focus on the importance of stream insertion and how flights can meet both tactical and strategic constraints and will briefly cover the TMI data being made available in the new TTP SWIM feed

Prescheduling with EOBTs

As the surface system is deployed across the NAS and fully integrated with existing FAA decision support, the roles of both ATC and Operators are expected to change. This will discuss first hand examples of this evolution as experienced at CLT
