Recommended Practices
21. The fluids must be used in accordance with the Approved Ground Icing Program. Application should respect the fluid manufacturers instructions and be applied in accordance with the most recent version of the SAE Aerospace Recommended Practice (ARP) 4737.
22. The FPDs used to de-ice aircraft in North America are usually composed of ethylene glycol or propylene glycol combined with water and other ingredients. The exact formulations of commercial fluids are proprietary; some contain wetting agents or corrosion inhibitors for specialized applications. Users can purchase FPD fluid in a concentrated form or pre-mixed, depending on customer requests.
23. The basic philosophy of using FPD fluids for aircraft deicing is to decrease the freezing point of water in the liquid or crystal (ice) phase.
