Briefing About Policy Issues of the 4D SAS and Potential CDM Involvement Warren Qualley, Harris Corporation (on behalf of the JPDO Weather Working Group s Policy Team) Presented at the 2011 NBAA Convention Las Vegas, NV October 11, 2011 1
Purpose Provide background about the JPDO Weather Working Group s Policy Team Discuss the NextGen 4D Weather Cube SAS Generate discussion about ways that the CDM can help move the NextGen 4D Cube SAS to reality 2
What is the Policy Team? Co-leads: FAA, NWS, Commercial Representatives from FAA, NWS, DoD, Commercial providers Bi-weekly meetings with focus on issues of Cube governance Work officially approved by the NextGen Executive Weather Panel (NEWP) 3
NextGen Executive Weather Panel Victoria Cox, Assistant Administrator for NextGen, FAA Dr. Jack Hayes, Assistant Administrator for Weather Services, NOAA Dr. Fred Lewis, Director of Weather, USAF Rear Admiral David Titley, Oceanographer, USN Dr. John Cavalowsky, Director of Airspace Systems Program Office, NASA Dr. Karlin Toner, Director, JPDO 4
Current Definitions of the Cube and SAS NextGen 4-D Wx Data Cube: A net-centric, virtual repository of weather state information for authorized aviation users. NextGen 4-D Wx SAS*: The primary source of weather information for the ANSP s Collaborative Air Traffic Management (ATM) decisions, supported by the same network services as the NextGen 4-D Wx Data Cube. * See next slide 5
NEWP-Approved (6/30/10) Definition of NextGen 4-D Wx SAS The 4-D Wx SAS is an optimal representation of all Air Navigation Service Provider (ANSP) weather state information used directly or translated into operational impact by the ANSP, and is consistent in time, space, and among weather elements. The 4-D Wx SAS is specified by the ANSP and is accessible to all users of the NAS. The 4-D Wx SAS is the source of weather information for ANSP's Air Traffic Management (ATM) decisions and is supported by the same network services as the 4-D Wx Data Cube. The ANSP will specify characteristics of weather state information needed to support its ATM decision-making and the corresponding decision support tools. As NextGen capabilities mature, the ANSP requirements will evolve. National Weather Service (NWS) will, in coordination with AF/Navy weather services, determine what weather state information best meets the 4-D Wx SAS requirements specified by the ANSP; information from any source, including commercial sources, can be used to meet SAS requirements as long as it can be freely distributed to all. With rare exceptions, the 4-D Wx SAS will be the only source of weather information for the ANSP s ATM decisions; however, it will not necessarily be the only source for other decision makers, such as pilots, dispatchers, and military operators. Making the 4-D Wx SAS both a support tool for the ANSP s ATM decisions and a NextGen resource provides both transparency and predictability in these decisions and shared situational awareness (SSA) for all NextGen participants. 6
Proposed Governance Structure 1 1. Convening Authority 2 2. Senior Management Council 3 3. Joint Agency Management Council Non-SAS Regulatory (QICP, DUATS) Verification (QMS) 4a. SAS Promotion (CDM WET) 4b. SAS Selection (CCFP) Wx Cube Standards (Netcentric Wx Data Activities) 4 Direct Authority Working Relationship 7
4-D Wx SAS Maturity Model SAS: A single 4-D dataset used across-the-board in ATM decisionmaking; the common weather picture. Alternative: A dataset approved for potential use as the SAS, but not currently the selected SAS. Candidate: A dataset which has been granted entry to the 4-D Wx Data Cube for purely evaluative purposes as a potential Alternative; not yet approved for use as the SAS
Near-Term NextGen 4-D Wx SAS Concept 1. Collaborative ATM 2. All ATM / ATC Decision-Support NextGen 4-D Wx Data Cube Boundary (TBD: Commercial Participation, Climatology, Archival Data, Pragmatic Exceptions, etc.) 3. Other End-Use Aviation Wx 4. Intermediate Aviation Wx 5. Public Wx Regulatory Wx 9
Far-Term NextGen 4-D Wx SAS Concept 1. Collaborative ATM 2. All ATM / ATC Decision-Support NextGen 4-D Wx Data Cube Boundary (TBD: Commercial Participation, Climatology, Archival Data, Pragmatic Exceptions, etc.) 3. Other End-Use Aviation Wx 4. Intermediate Aviation Wx 5. Public Wx 10
Questions for Discussion What products can CDM, beyond the CCFP, suggest for use in the SAS? How can CDM enhance/improve the weather information which will populate the SAS? How will commercial and academic groups be encouraged to develop innovative weather information for possible use in the SAS?\ Do you plan to use the SAS data for your operational decisions? If not, how do you envision working with the FAA knowing that they are using the SAS for their operational decisions? 11
