Relationship Between DAG-TM and Other Relevant Activities/Programs
In 1995, the RTCA Task Force 3 developed an implementation plan that represents a roadmap to NAS modernization. This led to various FAA and RTCA Concepts of Operation, ultimately resulting in the joint RTCA/FAA Concept of Operation for 2005. Additionally, in support of a 1997 AATT project milestone, AATT integrated the various concepts of operation into an overall AATT Concept of Operations which provided the vision for all AATT research. The DAG-TM Concept was formulated in the context of enhancing the various Concepts of Operation by adding a greater level of detail to the more “revolutionary” Free Flight applications outlined in the RTCA implementation plan (e.g., collaborative flow management and free maneuvering).
It is recognized there are a number of relevant activities (both within and outside of NASA) which directly relate to DAG-TM. It is critical that AATT-sponsored DAG-TM research leverage and build upon the results from these related activities, in order to maximize the limited research resources available. In addition, collaboration between NASA and the other organizations involved in these related activities is essential if DAG-TM is to be implemented. Some of these key relevant activities include:
.
NAS Architecture v4.0
.
Safeflight 21 Program
.
CPDLC Program
.
RTCA Activities
.
European Activities (e.g., FREER, NEAN, NUP)
.
Other NASA Programs (e.g., TAP, AvSP)
Conclusion
A concept definition for Distributed Air/Ground Traffic Management (DAG-TM) has been prepared by a multi-disciplinary team formed by the Advanced Air Transportation Technologies (AATT) project office. The DAG-TM concept, characterized by distributed decision-making between the flight deck, ATSP and AOC, is a NAS operations concept that increases user efficiency/flexibility and system capacity.
The DAG-TM Team recommends that this concept definition be evaluated as one potential extension of the various Free Flight implementation approaches currently under consideration.
