Briefing to the PAR-WG

  • FAA Systems Engineering Directorate


Background

  • FAA Flight Plan and Enterprise Architecture (EA) Provides the Direction for the Agency

    • The EA governs agency investments
    • EA required for all federal agency to satisfy OMB*
    • (*reference http://www.whitehouse.gov/omb/egov/a-1-fea.html)


Federal Enterprise Architecture

  • Objective of an Enterprise Architecture is to be Business Driven in Investment Decisions, It Supports:

    • Budget Allocation
    • Performance Measurement
    • Cross-Agency Collaboration
  • “…connects an organization’s strategic plan with program and system solution implementation by providing business and technology details to guide and constraint investments in a consistent, coordinated and integrated fashion.” – GAO-05-266

  • OMB A-130: The EA provides a strategy that will enable the agency to support its current state and also act as the roadmap for transition to its target environment.



FAA Enterprise Architecture Management



NAS Enterprise Architecture

  • NAS EA consists of service, operational and infrastructure views

    • Infrastructure Roadmap Consists of:
      • Automation
      • Communications
      • Surveillance
      • Navigation
      • Weather
      • Facilities
      • Mission Support
  • Focus for this Group is on Surveillance and Weather Roadmaps



Surveillance Roadmap Assumptions

  • Migrate to Automatic Dependent Surveillance - Broadcast (ADS-B) as primary means of surveillance

    • Airspace rule to be in effect and backup to be in place by 2020 (compliance date)
      • Existing surveillance infrastructure will remain in place until then
  • Backup to mitigate loss of on-board GPS positioning source required

    • Backup strategy in development, results expected by end of November 2006
    • Roadmap assumes reduced secondary surveillance network as backup (after 2020)
      • Dependent on Backup Strategy, Plan is to:
        • Retain all en route beacons (~150 monopulse systems with selective interrogation)
        • Retain limited set of terminal beacons (~ 40 monopulse systems with selective interrogation)
    • Terminal primary radars are retained
      • Dependent on Backup Strategy, Plan is to:
        • Need for additional systems dependent on emerging weather surveillance requirements; roadmap assumes all terminal primary radars required
        • Use as safety (ATC) backup in selected terminal areas (~100 locations)


Surveillance Roadmap Assumptions

  • Pending ADS-B Backup Strategy JRC approval, the ASR-11 program may be extended to replace a limited number of ASR-8/ATCBI systems

  • If Backup Strategy retains the Primary and Secondary Radars at selected locations past 2020, then additional tech refresh/SLEP work may be required

  • Surface primary radars no longer required after ADS-B rule compliance date

    • Requires mandated equipage of all surface vehicles
    • Surface surveillance to be supported by ADS-B
    • Multilateration will be retained as a backup to ADS-B at all ASDE airports
  • Multilateration will replace PRM system

  • Migration of en route Primary Radars to single agency/multi-user

  • En route primary radars not required for normal ATC operations





Surveillance Roadmap Decisions

  • 2007 - Investment decision for ADS-B/TIS-B/FIS-B Segment 2 (NAS wide) implementation, including backup strategy (limited secondary radar backup assumed as one of the options)

  • 2007 - Investment decision for legacy radar/beacon (ASR-8/ATCBI-4/5, ASR-9/Mode S) low activity refresh through 2020 (limited extension ASR-11 deployment)

  • 2009 – Investment decision for implementing IP address at radar facilities for distribution to all users

  • 2007 – Decision for JRC-2A approval of RWSL at selected airports

  • 2009 - Decision for migration of PRM to PRM-A, based on multilateration

  • 2012 – Decision for surveillance capability to support NGATS virtual tower implementation

  • 2014 - Decision for removal of surface primary radars, based on implementation of ADS-B

  • 2014 - Decision for replacement of legacy primary radars (ASR-8, ASR-9), based on air traffic safety and weather surveillance requirements

  • 2014 - Decision for en route and limited terminal replacement of legacy beacons (Mode S), and removal of remaining systems (Mode S, ATCBI-4/5)



Surveillance Roadmap Decisions

  • 2024 - Decision for replacement of en route beacons (ATCBI-6)

  • 2024 - Decision for replacement of terminal primary radars (ASR-11 PSR) and removal of terminal beacons (ASR-11 MSSR)



Weather Roadmap Assumptions





Weather Roadmap Decisions (1 of 3)





Weather Roadmap Decisions (2 of 3)



Weather Roadmap Decisions (3 of 3)



System Engineering Future Efforts and Plans

  • Develop Business Case analysis for primary radar for surveillance and weather

  • Support technology alternative analysis to address the roadmap decision points

    • Determine Requirements for Terminal Weather
    • Investigate Technologies to Improve Terminal Weather
    • Investigate Feasibility of a Scaled Down TDWR for Terminal Area
    • Investigate Improvement of CIWS Algorithms when using NWRT Data


FAA Expectation

  • Research needed to verify/validate:

    • Viability of Dual Use (Multi-functionality - weather, surveillance)
    • Affordability
    • Performance
