Environmentally Friendly, Non-Glycol Type I Aircraft Deicing Fluid
This paper describes Battelle's effort to demonstrate a bio-based, environmentally friendly, Type I, non-glycol deicer, called D3: Degradable by Design Deicer™. AMS 1424 D tests conducted by SMI and AMIL indicate this aircraft deicing fluid (ADF) meets the established physical properties, material compatibility, corrosion resistance, and deicing performance requirements. Its biological oxygen demand (BOD5) and lethal concentrations (LC50) are less than half of conventional Type I propylene glycol (PG) ADF levels. Spray tests were conducted in the McKinley Climatic Chamber at Eglin Air Force Base, and aircraft flight tests were conducted at the Niagara Falls Air Reserve Station.
