1 The Potential of Forced Air and Blend-to-Temperature BMPs at FedEx Regional Hubs

2 FedEx Express Facts Aircraft: Boeing MD10/MD Airbus A300/A Boeing Boeing Boeing 777Fs 291 Cessna 208s & ATRs Airport Locations: 375+ Hubs in Memphis, Indianapolis, Anchorage, Ft. Worth, Newark, Oakland, Greensboro, Miami, Paris, Guangzhou and Toronto Delivery Vehicles: 44,000+ Average Daily Volume: 3.5MM Packages/12 MM lbs. 2

3 Cargo Challenges Schedule minutes matter Coordination of aircraft into hubs Off loading/loading aircraft Equalizing volume through sort facility Late departures from the field have a domino effect on the arrival pattern at the hubs. These delays can in turn have system-wide impacts when late flights delay the sorts and subsequently the hub launches. 3

4 Deicing Preferences Gate/ramp deicing Maximize collection / minimize usage Storm water diversion/collection Glycol recovery vehicles Plug and pump Forced air deicers Blend to temperature ANC, IND, MEM, EWR, GSO and CDG Consolidated collection pads/areas on or adjacent to ramps 4

5 Forced Air Deicers Utilizes high velocity air with ADF Air only, fluid only, air w/ fluid, air w/ fluid injection Over 100 currently in FedEx Express fleet ADF savings could be significant, but dependent on variables, including: Weather conditions Best conditions: Light, dry snow Less favorable conditions: Heavy snow, ice Time and schedule constraints Operator training Operator experience Practice = Proficiency 5

6 Forced Air Deicer Controls Left Control Right Control 6

7 Forced Air Deicers Quantification of ADF savings? Weather conditions? Type/amount of precipitation during and deicing and layover Operator variables? Experience, training, proficiency Type of aircraft? Length of aircraft layover? Aircraft orientation during layover? Other Intangibles? 7

13 FedEx AFW Regional Hub AFW Regional Hub Opened in 1997 Few deice events/year 2 to 4 Stringent stormwater discharge limits Solution Divert drainage from both taxiway throats to underground storage tanks during deicing events Flush deicing collection system after events Discharge collected fluids trucked off-site to POTW 13

14 FedEx GSO Regional Hub GSO Regional Hub Opened in 2009 Deicing areas located at taxiway throats (shaded yellow) Deice event drainage diverted to adjacent 300,000 gallon underground vaults (shaded blue) Metered discharge from vaults to the POTW 14

17 Conclusions There are no one size fits all solutions to deicing BMPs Even within airports, there may be different solutions in different areas or between the passenger and cargo areas Solutions require consideration of: All appropriate BMPs Airport-specific environmental issues and constraints Location-specific & tenant operational constraints 17
