Cloud Liquid Water Content Measuring Equipment for the Nomad N24 Aircraft Flight Icing Trials of 1978-1979.

Abstract : This report describes spray rig tests on the liquid water content meters used in the Noman N24 aircraft anti-icing trials held in 1978-1979. One instrument was based on a prototype designed by the CSIRO. A complete evaluation of this instrument was undertaken. The other was commercially available and accepted for flight icing trials use by the US Federal Aviation Authority and the Australian Department of Transport. Provided certain precautions were taken, both instruments performed satisfactorily over the range of liquid water contents and airspeeds required for Nomad certification.
