1. 1 Winter Operations Program Presented by Ken Greene October 10, 2011

2. Snowman Program – Coordination position instituted during the 2006/2007 season – single point of contact for the Air Traffic Control Tower for the overall airport plan – coordinates with Aviation Operations Managers on crew movements – Builds relationships and trust with our partners – Federal Aviation Administration (FAA) – Airport’s Control Tower – Terminal Radar Approach Control Center (TRACON) – Air Traffic Control System Command Center (ATCSCC) 2

3. Predictability – Runway occupancy times – prior to 2006 - times were unpredictable and lengthy (45 minutes or longer) – 2006/2007 – began improving times and establishing consistency – better plan – more equipment – more personnel – times have improved each year 3

4. Predictability 4 – 2009/2010 – Average 17 minutes – Minimum 11 minutes – Maximum21 minutes – 2010/2011 – Average16 minutes – Minimum11 minutes – Maximum18 minutes

5. Predictability – Priority pavement system – prior to 2006 – attempted to clean everything – 2007 – developed new Snow and Ice Control Plan that includes a priority pavement system – plan is reviewed and adjusted prior to each snow season with input from: – Airport Operations and Maintenance Divisions – FAA – air traffic management staff – air carriers 5

6. Current System 6

7. Consistency – Consistent snow removal routes – two (2) runway teams – two (2) taxiway teams – hotshot teams (assigned as needed) – Crew movements are predictable – Ground and Local Controllers are able to predict crew movements – Controllers can begin adjusting aircraft taxi routes to keep crews moving 7

8. Metrics – Prior to 2006 – did not formally keep track of runway occupancy and closure times – Began tracking times during 2006/2007 season – closure times – equipment occupancy times – runway friction test times – times from runway opening to first aircraft – Future – plan to track differences in agreed upon closure/opening vs. actual closure/opening times 8

9. Personnel (Operations) – Six (6) dedicated Aviation Operations Managers (rotation) – Located in FAA Tower Cab during snow removal activities – One (1) Aviation Operations Manager from 0500L- 2300L – Double staffing for snow emergencies – Participate on FAA Command Center planning telecons – Coordinate airfield snow removal plan with fellow Aviation Operations Managers 9

13. Weather Forecasting – Planning forecast – twelve(12) to twenty-four (24) hours prior to an event – Tactical forecast – three (3) to six (6) hour intervals – Maintenance Decision Support System – weather forecast – pavement forecast – Pavement forecast with suggested treatment (future) – adjusted surface temperature – accumulation amount – type of accumulation 13

14. Weather Forecasting – Contract Forecaster – Northwest Weathernet – forecast focused on DIA – written forecast provided every twelve (12) hours – updates provided when necessary – available for phone calls – participates in planning and tactics meetings – National Weather Service – Probabilistic forecast – specific to DIA – short term and long term discussion – snowfall in six (6) hour increments 14
