This document 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 document 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
