RightSizing Briefing to The Friends and Partners in Aviation Weather

Victor Passetti, PMP, leads the project to improve and right-size the sensor network for better efficiency, reliability, and reduced costs in aviation weather services. Challenges with current systems prompt the need for a more flexible and advanced Terminal Sensor Network (FTSN) concept. The project aims to demonstrate the upgraded sensor network's capabilities in a three-season demo, showcasing enhanced coverage and data processing, leading to significant cost savings.

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

  2. OI - 103122 The sensor network will be improved and right-sized to ensure formation sufficiency, reliability, and availability while reducing life-cycle costs.

  3. FAA currently owns multiple weather sensor systemsMost are past their design lifeCosts to maintain are increasingClosed designs limits future enhancements Current Legacy Systems New Gen RVR first fielded ’88 259 airport systems LLWAS first fielded ’81 89 systems Federal AWOS first fielded ’86 200 systems ASOS first fielded in ’88 987 systems AWSS first fielded ’99 60 systems

  4. Challenges with Current Capabilities Runway 27R • 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

  5. Issues with Current Prevailing Visibility Report Visibility and Wind Too Close to Obstructions

  6. Current – Most Sensors (excluding RVR) Not Optimally Sited Philadelphia International Airport Legacy Sensors Sites

  7. FTSN Concept - Flexible, Multi-Function Sensor Siting

  8. Concept - Flexible Terminal Sensor Network (FTSN) ASOS-AUX ASOS AWOS AWSS FTSN Sensor interface to SWIM that collects, consolidates and processes all airport sensor data RVR LLWAS

  9. 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

  10. Project Activities – FTSN Concept Demonstration • At the WJHTC • July 31, Aug 1, and 2 • Collector Equipment and Functional Demonstration • Canned sensor data • To mimic terminal coverage • Live sensors • In laboratory environment • Demonstrates communication with Collector • Wireless • Emulation software • To trigger “events”

  11. Project Activities – FTSN Three Season Demo • Demonstrate wireless network concept • Face outdoor challenges/weather
