11 # OF AIRCRAFT PER HOUR THAT AIRPORT CAN ACCEPT 60 AT SFO ON SUNNY DAY. TMU 2012 Federal Aviation Administration

12 ONCE CLOUDS <=3000 OR VIS <=5SM LOSE VISUAL APPROACHES # OF AIRCRAFT THE AIRPORT CAN LAND DROPS IN HALF FROM 60 TO 30. TMU 2012 Federal Aviation Administration

13 FAA HAS TO DO SOMETHING WITH ALL THE SCHEDULED AIRCRAFT TO LAND THAT EXCEED THE AIRPORT LANDING RATE OF 30.. GROUND STOPS, GROUND DELAY PROGRAM, INCREASED AIRBORNE SPACING MIT. TMU 2012 Federal Aviation Administration

17 SIMUL 9 TO WEST FLOW AT ORD TMU 2012 Federal Aviation Administration

18 OHARE = WEST or EAST LANDING AIRPORT. (West Flow) = 114 AC/HR (EAST Flow) = AC/HR

19 OHARE = IF CANNOT LAND WEST or EAST BIG PROBLEMS. (West Flow) = 114 AC/HR (EAST Flow) = AC/HR South Flow Configuration (STRONG SOUTH WINDS = AC/HR

20 A Few ORD Weather Scenarios ** FAA NEEDS SEVERAL HOURS LEAD TIME (PLANNING TIME) ON CHANGING CEILINGS/VISIBILITY and WINDS Chicago Aviation Support National Weather Service ZAU- Aurora, Il 20

21 Current Time

22 **** NOW ORD HAS SIGNIFICANT SURPLUS AC Arrival rate due to DUE TO STRONG GUSTY SOUTH WINDS

23 A QUICK LOOK AT MDW Chicago Aviation Support National Weather Service ZAU- Aurora, Il 23

24 FOUR POSSIBLE CONFIGURATIONS. MDW MAY ONLY LAND ONE ARRIVAL RUNWAY AT A TIME! AC PER HOUR 28-32

25

26 Midway favors Landing from the south ( 4R or 31C) BECAUSE THEY ARE DIRECT APPROACHES.

27 ** IF LANDING SOUTH. CEILINGS drop BELOW 1500 or VIS below 5SM MDW unable to make this circle approach.

37 Thunderstorm Hazards Hail Hailstones grow by collision with supercooled water drops with ice nuclei. FL500 *** UPDRAFT STRENGTH OF APPROX. 55MPH IS NEEDED TO SUSPEND 1 HAIL ALOFT. (SPEEDS CAN APPROACH/EXCEED 100MPH!) HAIL CAN BE LOFTED UP AND OUTSIDE, AWAY FROM THUNDERSTORM AS IN THE FOLLOWING PHOTO.
