Deliverable D6.1 / D6.2 provides information on the calibration method for Appendix O Freezing Drizzle and Freezing Rain cloud conditions in Icing Wind Tunnels. Recommended instrumentation for the different parameters as well as applicable procedures are described in order to assist the calibration. The document is structured in a similar way to the Aerospace Recommended Practice SAE ARP5905, “Calibration and Acceptance of Icing Wind Tunnels”, which is used for calibration of Appendix C icing clouds [1]. This deliverable aims to act as additional input for the SAE AC-9C Aircraft Icing Technology Committee for IWTs working on the document SAE AIR6241 SLD capabilities of icing wind tunnels were commonly accepted procedures for the experimental simulation of Supercooled Large Drop (SLD) conditions in icing wind tunnels along with measurement techniques suitable to obtain calibration of the SLD icing cloud will be summarised.
