Water Content Instrumentation for Icing Cloud Characterization
This SAE Aerospace Information Report (AIR) provides a comprehensive overview of primary water content measurement instrumentation, for both facility-based icing research and in-flight icing research, over the range of commonly used aircraft certification icing envelopes. It includes information on the theory of operation of the instruments, system errors and limitations, and practical considerations when using them for cloud characterization. This document does not address other icing cloud measurements of interest, such as particle sizing, or measurement of phenomena such as snow, sleet, or hail.
The need for a single, comprehensive document providing guidance on instrumentation that measures liquid, ice, and total water content in supercooled, mixed-phase, and glaciated clouds was identified. This document would eliminate duplication of effort as the information appears sporadically in several other SAE documents. This SAE Aerospace Information Report (AIR) is intended to be the definitive source for such information.
