U.S. Air Force Deicing Initiatives : U.S. Air Force Deicing Initiatives Aeronautical Systems Center Ms. Mary Wyderski Aeronautical Systems Center Wright-Patterson AFB, Ohio Great Lakes Regional Pollution Prevention Roundtable September 23, 2004


Overview : Overview Air Force Concerns Current Activities Future Air Force Direction Funding Avenues 2004 Deicing Working Group Summary


Air Force Concerns : Air Force Concerns Federal, state and local EPA constraints on operations Environmental drivers Clean Water Act Amendment 1990 EPA Effluent Limitation Guidelines 1999 BOD, toxins, significant water usage and waste stream Permits and fines Water conservation Deicing materials, non-toxic, non-permitting, new formulations Cost Deicing burdened cost: ~$3.00(s) for each dollar spent for fluid


Air Force Concerns (cont.) : Air Force Concerns (cont.) War Readiness Stress on manpower and infrastructures Reforms Modification of Military Specifications and Standards, where possible, to adopt Commercial Specifications More aircraft launch requirements Performance of deicing materials and testing for compatibility with unique Air Force aircraft materials


Slide5 : Current Activities Aircraft materials compatibility test program DoD Deicing Test Facility Niagara Falls Air Reserve Station designated as test facility by DoD’s SERDP/ESTCP office Deicing and Anti-Icing Pollution Prevention Technology Roadmap Deicing website https://www.en.wpafb.af.mil/env/envv_deicing.asp Investigating potential sources of integrated infrared heating for mobile unit


Slide6 : Current Activities (cont.) Three non-propylene glycol based aircraft deicing fluids at various stages of evaluation - D3, ADF-2, Foster-Miller Ice detection system evaluation Icephobic coating evaluation Military Test Method Standard (MTMS) Currently draft document Process for acceptance of fluids/materials


Current Activities (cont.)Air Force Deicing Materials Procurement : Current Activities (cont.) Air Force Deicing Materials Procurement


Future Air Force Direction : Future Air Force Direction Research & Development effort to understand melting of snow, ice and frost Continue looking for non-fluid solution Continue work with ice detection system evaluation Continue work with icephobic coating evaluation


Slide9 : Future Air Force Direction (cont.) Annual Workshop Teaming, Training, Equipment, etc. Update Aircraft Deicing Pollution Prevention Technology Roadmap Establish a stable fund line within Air Force for aircraft deicing efforts More effective workshops


Future Air Force Direction (cont.) : Future Air Force Direction (cont.) Overall Strategy Reduce cost Ensure flight safety Minimize use of fluids if practical Reduce logistics footprint Teaming Adopt commercial specs/standards and procedures


Funding Avenues : Funding Avenues Potential funding sources for environmental initiatives Pollution prevention funding SERDP/ESTCP Aircraft program Office funding Small Business Innovative Research funding Other(s)


2004 Deicing Working Group : 2004 Deicing Working Group Goal: Provide flying capability to the operator, while maintaining environmental compliance Primary objectives Promote information exchange among deicing stakeholders Discuss problems Identify potential courses of action Create action plans Focused on aircraft, runway, and inflight deicing Special emphasis on operational concerns, present practices, and emerging technologies


2004 Deicing Working Group (cont.) : 2004 Deicing Working Group (cont.) Conducted 15-17 March 2004 in Las Vegas NV 84 attendees Diversity of group revealed different priorities, focuses and perspectives Operational folks – mission readiness System Program Offices – impacts to aircraft Environmental – protect environment, ensure EPA does not effect base operations FAA – experiences, commercial way of operating General consensus - Working Group was needed and successful Intend to meet regularly (e.g., annually)


Summary : Summary Much activity underway to develop ways to mitigate/minimize environmental impacts and enhance safety Training, equipment, definite requirements Future deicing chemicals and technologies must be approved by Program Manager Reduced manpower & funding with increased operations require more effective and efficient operations….faster, cheaper, less manpower

Current/Future Activities (cont.)Materials Compatibility Test Program : Current/Future Activities (cont.) Materials Compatibility Test Program Follow on material compatibility test programs New deicing materials Runway: RDF-2, potassium formate Aircraft: ADF-2, D3, Foster-Miller Same materials as previous program New aircraft materials Low observable materials High-Velocity Oxygen Fuel (HVOF) coatings Lubrications/sealants Electrical connectors Same deicing materials as previous program New aircraft materials and new deicing materials


Current/Future Activities (cont.)Materials Compatibility Test Program : Current/Future Activities (cont.) Materials Compatibility Test Program Purpose / benefits of Military Test Method Standard (MTMS) Ensure procurement of deicing materials compatible with unique materials Prevent or reduce chance of damage to structural materials that are unique To make Air Force aware that there may be a problem


2004 Deicing Working Group (cont.)Concerns/Challenges Identified : 2004 Deicing Working Group (cont.) Concerns/Challenges Identified Col Smith, Nellis AFB – “Speak with One Voice” Multi-service effort AF transformation impacting operations hourly Need to approve use of anti-icing fluid Process and time required to test and approve new runway and aircraft deicing/anti-icing products Clear identification of requirements by users Understanding of process implementation


2004 Deicing Working Group (cont.)Concerns/Challenges Identified : 2004 Deicing Working Group (cont.) Concerns/Challenges Identified Need standardized training program Deicing equipment deficiencies and standardization Currently solving problems by pieces instead of overall


2004 Deicing Working Group (cont.)Concerns/Challenges Identified : 2004 Deicing Working Group (cont.) Concerns/Challenges Identified Moving toward commercial specs and standards resulting in limited performance testing by manufacturers SAE AMS aircraft deicing fluid specs may not be sufficient for qualification of currently developmental non-propylene glycol based fluids Market awareness: need a single POC for emerging technologies
