2. RightSizing Briefing to The Friends and Partners in Aviation Weather Victor Passetti, PMP RightSizing the Sensor Network Project Lead August 8, 2012

3. Federal Aviation Administration FPAW Briefing August 8, 2012 3 3 OI - 103122 The sensor network will be improved and right- sized to ensure formation sufficiency, reliability, and availability while reducing life-cycle costs.

4. Federal Aviation Administration FPAW Briefing August 8, 2012 4 FAA currently owns multiple weather sensor systems Most are past their design life Costs to maintain are increasing Closed designs limits future enhancements ASOS first fielded in ’88 987 systems Federal AWOS first fielded ’86 200 systems New Gen RVR first fielded ’88 259 airport systems LLWAS first fielded ’81 89 systems AWSS first fielded ’99 60 systems Current Legacy Systems

5. Federal Aviation Administration RWI – Weather Forecast Improvements PMR September 2010 55 Federal Aviation Administration FPAW Briefing August 8, 2012 Challenges with Current Capabilities Overlapping sensing elements Closed systems do not effectively share data Proprietary processors and software difficult to maintain and harder to change Systems rely on hardwire and RF links which are costly and difficult to sustain Sensors no longer state of the art Becoming more difficult to maintain aging hardware exposed to the elements Runway 27R

6. Federal Aviation Administration RWI – Weather Forecast Improvements PMR September 2010 66 Federal Aviation Administration FPAW Briefing August 8, 2012 Issues with Current Prevailing Visibility Report Visibility and Wind Too Close to Obstructions

7. Federal Aviation Administration RWI – Weather Forecast Improvements PMR September 2010 77 Federal Aviation Administration FPAW Briefing August 8, 2012 Current – Most Sensors (excluding RVR) Not Optimally Sited Philadelphia International Airport Legacy Sensors Sites

8. Federal Aviation Administration RWI – Weather Forecast Improvements PMR September 2010 88 Federal Aviation Administration FPAW Briefing August 8, 2012 FTSN Concept - Flexible, Multi-Function Sensor Siting

9. Federal Aviation Administration RWI – Weather Forecast Improvements PMR September 2010 99 Federal Aviation Administration FPAW Briefing August 8, 2012 Concept - Flexible Terminal Sensor Network (FTSN) Sensor interface to SWIM that collects, consolidates and processes all airport sensor data

10. Federal Aviation Administration RWI – Weather Forecast Improvements PMR September 2010 10 Federal Aviation Administration FPAW Briefing August 8, 2012 Enterprise Architecture - Typical Large Airport Eliminate Hundreds of Central Processing Equipment Cabinets Eliminate Thousands of Field Processor Equipment Cabinets Eliminate Thousands of Sensors Increase Sensor Coverage and Number of Measurements More Data Available to More Users Save $170 Million Plus on Equipment Alone
