1 (A collaborative project between GTAA, C-MORE and Team Eagle) 1

2 ▪100,000 PAX/day ▪2nd largest entry point for international PAX into North America ▪Ability to handle more than 38 million per year ▪6666 low-visibility centerline lights Toronto Pearson Facts & Figures 2

3 Project Scope Can GTAA optimize the low-visibility lighting system inspection program without materially reducing safety, reliability and compliance? Do we have any data? How to analyze the data? 3

6 The operational standards published by Transport Canada required the Canadian airports to: Have less than 5% faulty centerline lights Not to have more than 2 faulty centerline lights in a row Operational Standards Burned out light ON light 1 2 6

7 To minimize the total cost of inspection of centerline lights by optimizing their inspection interval while complying with the Transport Canada’s regulations Objectiv e Methodolo gy Conditio n 1 week 7

8 The data in the Excel file are used to create and organize Lights file, Inspection file and Faults file. Faults File Inspections File Lights File Database Management System Create Database 8

9 Repeated faults Unidentified lights Incomplete inspection data before 2007 Database Challenges Solution > 9

10 Database Management System Reading the Excel file Creating necessary files to support analysis Providing custom lists of lights, inspections and faults Graphical & User-Friendly Interface Lights search tool Creating groups of lights Showing lights on the map Analysis Single Light Reliability Analyzer Compliance Reliability Analyzer Cost Analyzer Optimal Inspection Analyzer Features 10

11 Location Faults Specifications LIGHT Light ID Light Type Location Name Location ID GPS Fault Type Number of Faults Date Lights Example 11

12 Load data for first light ID Last light ID? END Load data for next light ID Specifications Location test Fault test Add this light to selected lights PASS FAIL PASS FAIL PASS NO YES START Lights Search Select Lights Selected Lights Map Select Group 8 12

13 Definition: Compliance reliability of a group of lights is defined as the yearly probability of fulfilling the operational standards established by Transport Canada. Compliance Reliability Number of Lights Single Light Reliability Operational Standards Note: Compliance reliability is a function of: 1 2 3 13

14 Most faults (>90%) were of centerline lights, and most of these faults were “Burned Out” FAULT TYPES Most faults (>90%) were of centerline lights, and most of these faults were “Burned Out” 14

15 Yearly Inspections 15

16 Minimum level of system reliability: 99% OPTIMIZED INSPECTION INTERVAL 16

17 Number of lights shown = Toronto Airport Map 17

18 The inspection interval of low-visibility lights can be optimized to save time and cost. The optimized inspection interval is different from one taxiway to another. In each specific taxiway the lights in different locations may have different levels of reliability. Working with Team Eagle and CMORE to commercialize this. Conclusion 18
