Aircraft with Airborne Icing Spraying Systems AISS have been used for some time to generate icing clouds into which test aircraft could be flown to show compliance with the requirements of FAR XX.1093. However, the spray arrays used and the relatively large distance between the AISS and aircraft parts to be tested precluded small droplet sizes at high liquid water content at most atmospheric conditions. Some of these shortcomings were overcome by mounting the AISS directly on the test aircraft. This proved to be a very efficient method to develop and certify individual aircraft components. This report describes the methodology and test procedure used with an AISS mounted on a test aircraft to show compliance with FAR 29.1093 for the newly developed inlet of the Bell 222250-C30G helicopter conversion. Development and certification testing was accomplished in a 4-week period.... Aircraft ice protection, Airborne icing spraying system, AISS, Icing, Inlet.
