Methods and Processes for Evaluation of Aerodynamic Effects of SAE Aircraft Ground Deicing/Anti-icing Fluids
This ARP documents methods and processes that may be utilized by aircraft manufacturers (or type certificate holders, researchers, or others) to evaluate the aerodynamic effects of SAE aircraft ground deicing/anti-icing fluids (“fluids”) when applied to specific aircraft.
The qualification processes for SAE aircraft ground deicing/anti-icing fluids is described in ARP 5718, and the standards, including aerodynamic standards, with which the fluids must comply are given in AMS 1424 (Type I) and AMS 1428 (Types II, III, & IV). These standards require that the aerodynamic performance of all fluids be tested and qualified in accordance with AS5900, the Aerodynamic Acceptance Test (“AAT”). The purpose of the AAT is to ensure that new fluids have aerodynamic performance properties that are not worse than an established, accepted standard. In this way, the AAT provides a general screening of the aerodynamic effects of the fluids. Even with successful AAT qualification, however, there can be circumstances which require evaluation of the aerodynamic effect of the fluids on specific aircraft. The intent of this ARP is to provide guidance to aircraft manufacturers by describing methods that have previously been used to evaluate the aerodynamic effects of fluids, as well as methods currently under development. It also provides background information and additional considerations regarding aircraft ground deicing/anti-icing fluids.
