This SAE Aerospace Information Report (AIR) provides definitions for terms commonly used in aircraft inflight icing system design and analysis, research, and operations. Some general thermodynamic terms are included that are frequently used in icing analysis, but this document is not meant to be an inclusive list of such terms.
The purpose of this document is to provide an assemblage of definitions for terms commonly used in aircraft icing. Over time, the field of aircraft icing has evolved a set of terms that are sometimes used in different ways and have different meanings. This document is a compendium of icing terms and their associated definitions.
The SAE does not endorse or recommend any particular definition given in this report.
