Quality Assessment Report: Integrated Icing Diagnostic Algorithm (IIDA)

Abstract This report summarizes,verification results for the Integrated Icing Diagnostic Algorithm (IIDA), which is designed to diagnose the existence of in-flight icing conditions aloft. The report was prepared by the Quality Assessment Group of the Aviation Weather Research Program’s Aviation Forecast and Quality Assessment,Product Development,Team. The purpose,of the report is to summarize the quality of IIDA diagnoses, in anticipation of IIDA’s transition through the D4/D5 decision point of the Aviation Weather Technology Transfer process. The report includes (a) a brief summary,of previous evaluations of IIDA and other in-flight
