1. Presented to: Phased Array Radar Working Group By: Jim Williams Date: 5 December 2006 Federal Aviation Administration Briefing to the PAR-WG FAA Systems Engineering Directorate

2. Multi Function Phased Array Radar 2 Federal Aviation 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)

3. Multi Function Phased Array Radar 3 Federal Aviation 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.

5. Multi Function Phased Array Radar 5 Federal Aviation Administration 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

6. Multi Function Phased Array Radar 6 Federal Aviation 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)

7. Multi Function Phased Array Radar 7 Federal Aviation 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
