This SAE Aerospace Recommended Practice (ARP) describes methods that are known to have been used by aircraft manufacturers to evaluate aircraft aerodynamic performance and handling effects following application of aircraft ground deicing/anti-icing fluids (“fluids”), as well as methods under development. Guidance and insight based upon those experiences are provided, including: Similarity analyses. Icing wind tunnel tests. Flight tests. Computational fluid dynamics and other numerical analyses. This ARP also describes: The history of evaluation of the aerodynamic effects of fluids. The effects of fluids on aircraft aerodynamics. The testing for aerodynamic acceptability of fluids for SAE and regulatory qualification performed in accordance with AS5900. Additionally, Appendices A to E present individual aircraft manufacturers’ histories and methodologies which substantially contributed to the improvement of knowledge and processes for the evaluation of fluid aerodynamic effects. Text clarification at 4.4.3.2.1.2 to better representing industry practices. New reference from FAA added. Inclusion of middle speed ramp at 3.3.2, and wording harmonization with AS5900. Notes referring to development history of high-speed, low-speed, and middle-speed ramps added. Minor editorial corrections. Change in title of Figure A1.
