1 TRANSPORTATION RESEARCH BOARD LED Airfield Lighting System Operation and Maintenance Wednesday, November 14, :00-3:30 PM ET

2 Purpose Discuss research from the Airport Cooperative Research Program (ACRP) s Report 148: LED Airfield Lighting System Operation and Maintenance. Learning Objectives At the end of this webinar, you will be able to: Understand the design factors used to determine whether LED fixtures are appropriate for your airport Discuss how maintaining LED fixtures differ from traditional incandescent fixtures Understand important considerations for LED circuits, and the impacts of co-mingling LED and incandescent Describe how recent trends in the industry for bolt types and torqueing specifically impact LED systems

3 ACRP is an Industry-Driven Program Managed by TRB and sponsored by the Federal Aviation Administration (FAA). Seeks out the latest issues facing the airport industry. Conducts research to find solutions. Publishes and disseminates research results through free publications and webinars.

13 Agenda Introduction Purpose & Objective Impacts to Maintenance Environmental Factors Advancements Photometric & Chromaticity Technological Impacts Return on Investment Energy Reduction Circuit Size and Configuration Additional Information Questions

14 Introduction The rapid advancement of LED airfield ground lighting technology caused a surge to convert airfield lighting systems to the newer technology. As more of the legacy systems were replaced, it was evident the current industry standards and practices would also need to be updated.

15 Research Problem To develop a best practice and operations guidebook for the use of LED airfield ground lighting systems, utilizing the combined knowledge and practices of maintainers, end users and manufacturers.

16 Approach Analyze Vendors, FAA ACs Data Collection Polled 49 airports, 29 question survey In Depth Investigation Case studies from 12 airports Compile Research into Best Practices Guidebook

17 Airports Surveyed

18 Case Studies

19 Impacts to Maintenance Understand and follow FAA AC 150/ C Maintenance of Airport Visual Aid Facilities Replace rather than repair Maintain wearable items on fixture without voiding warranty Service contracts with lighting vendor Asset management Airfield lighting fixture bolt torqueing Maintain open dialogue with vendor

20 Impacts to Maintenance (cont.)

21 Environmental Factors for LED Lighting Systems Moisture Most common issue for LEDs Water is in lighting infrastructure constantly Early generations of fixtures were not encapsulated Longer lamp life equates to less frequent inspection

22 Moisture

23 Environmental Factors for LED Lighting Systems (cont.) Vibration More failures of T/W CL fixtures at high speed exits May have an affect on bolts Infrequent maintenance can make matters worse Boeing Empty operating weight: 406,000 lbs. Max landing weight: 652,000 lbs. Max takeoff weight: 910,000 lbs.

24 Asset Management Create an inventory of assets on the airfield Fixture generation (Model #) Warranty period Spare parts Develop a maintenance schedule with alerts Review work orders Track work orders durations Maintain inventory After data collection is complete, a heat map can be created

25 Asset Management (Cont.) Heat map

26 Asset Management (Cont.) Fixture addressability Allows user ability to view light fixture information via a tablet and Bluetooth connection Enables user to view vital information such fixture type, install date, maintenance history, etc. Tools Preset torque wrench capable of delivering real time data to the asset management system More accurate Tool itself becomes a maintenance item

27 Photometric & Chromaticity Photometric Properties Light output Light intensity dimming curves Chromaticity Coloration

28 Photometric & Chromaticity FAA AC 150/ D FAA AC 150/ D Output Graphically L-850A

29 Photometric & Chromaticity Mismatched light intensity output (Dimming curve) Uneven light output in intermediate operational intensity settings FAA EB #67 Light Sources Other Than Incandescent and Xenon for Airport and Obstruction Lighting Fixtures FAA AC 150/ D

30 Photometric and Chromaticity Aerospace Standard AS25005 General Requirements for Colors, Aeronautical Lights and Lighting Equipment International Commission on Illumination (CIE) Mixture Diagram

31 Photometric and Chromaticity Both light fixtures meet standard Eye detects difference in chromaticity

32 Photometric and Chromaticity Verify color coordinates & color spectrum Test & verify system photometric output Move to a 5-step TW centerline system

33 Technological Impacts Heaters EB 67D Arctic Kit Test Requirements In still air and with the light source activated at the highest intensity setting, the main beam light emitting surface temperature must rise a minimum of 15 C after 30 minutes operation. No test requirements on lower steps

34 Technological Impacts (Cont.) Heaters Factors and considerations for heaters: Precipitation Type Snow Removal Procedures Light System Operation Most airports surveyed did not use heaters

35 Return on Investment Cost was initial greatest concern LED lighting grew from 20% to over 80% Understanding ROI of LED vs. non-led LED higher initial investment cost Pay Back Non-LED has back end costs time

36 Return on Investment Energy cost Varies from Region to Region Maintenance cost Significant Issue Impacting ROI Fixture cost Refurbishment cost Fixture damage rates Category of Cost Percent Savings Costs Lamp Replacement Labor Cost Energy Cost 4.2% $3, % $60, Material Cost 24.8% $21,000.00

37 Return on Investment ROI Focus is Shifting Energy Reduction Improved Reliability Decreased Quartz Inventory Decreased Fixture Demand

38 Energy Reduction The large capital investment has shifted to planned and coordinated conversion projects Focus on Return on Investment (ROI) shifted to potential energy reduction

39 CIRCUIT SIZE AND CONFIGURATION Engineers and designers have to work with the airport to establish circuit configurability Fixture Replacement 100% Extending Circuit 100% 90% Reduce CCR 100% 70% 40% CCR Capacity Circuit Load CCR Capacity Circuit Load CCR Capacity Circuit Load Low cost Poor power factor negates efficiency Maintain good power factor Maintenance challenge with keeping larger circuits active Higher cost Maintain circuit size, power factor and efficiency
