Administration

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)


Administration

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.

Administration


• 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


Administration

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)


Administration

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– At non ASDE-X location full Multilateration is required

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

• En route primary radars not required for normal ATC operations

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)

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 airports2009 - Decision for migration of PRM to PRM-A, based on multilateration2012 – Decision for surveillance capability to support NGATS virtual tower

implementation2014 - Decision for removal of surface primary radars, based on

implementation of ADS-B2014 - Decision for replacement of legacy primary radars (ASR-8, ASR-9),

based on air traffic safety and weather surveillance requirements2014 - Decision for en route and limited terminal replacement of legacy beacons

(Mode S), and removal of remaining systems (Mode S, ATCBI-4/5)

Weather Roadmap Assumptions

Weather Sensor Sustainment Issues • Weather information from ASR-9/11 continues to be required even if

surveillance no longer ground based (6-level weather channel)• Evaluate need for Wind Shear/Microburst functionality to be ground based (SE

study)• Rulemaking to support equipage for in situ aircraft observations (MDCRS and

TAMDAR-like systems)

Migrate Weather to common Network Enabled Operations (NEO) communications

Issues re Convergence of Wx Processing Capability• Develop CWI (CIWS-WARP Integration)

o Weather and Radar Processor (WARP) End of Serviceo Continuation of Corridor Integrated Weather System (CIWS) prototype until CWI “stands

up”

• Develop NGATS General Weather Processor (GWP)o Fund NGATS GWPo GWP subsumes most of the functionality of CWI and ITWS (may not be FAA ‘box’)

Fund FAA portion of NGATS 4-D “virtual distributed” database (Wx Fuser)

• 2009 – Begin CRD to acquire & deploy first wake turbulence mitigation

ATC decision support (Wake Turbulence Mitigation for Departures

<WTMD>) capability for airports with CSPR

o 2011 – Investment decision to add Wake Turbulence Mitigation for Arrivals (WTMA) ATC

decision support capability for airports with CSPR

o 2016 - Investment decision to add Wake Turbulence Mitigation for Single Runway (WTMSR)

decision support capability to allow reduced wake turbulence spacing for aircraft directly

following another aircraft (arrivals and departures) airports with CSPR

o 2019 – Investment decision to add Aircraft Based Wake Turbulence Separation (ABWTS)

decision support capability to the flight deck. Aircrew can “visualize” in all weather

conditions the wake hazard zones associated with adjacent and approaching aircraft and

self separate from that hazard zone.

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


Administration

FAA Expectation

• Research needed to verify/validate:– Viability of Dual Use (Multi-functionality -

weather, surveillance)– Affordability– Performance
