Reply to 'Comments on 'Characterization of Aircraft Icing Environments withSupercooled Large Drops for Application to Commercial Aircraft Cerification'

摘要

Cober et al. (2009) and Cober and Isaac (2012) characterized aircraft icing environments that contained supercooled large drops (SLD) > 100 /xm in diameter on the basis of data collected during 134 research flights into winter storms in three geographic regions of North America. The characterization was designed to be supplemental to existing aircraft icing certification envelopes, given that existing envelopes do not explicitly incorporate SLD conditions. The U.S. Federal Aviation Administration isconsidering using the results from Cober et al. (2009) and Cober and Isaac (2012) as the basis for new certification regulations. Marwitz (2013) has suggested that the results of Cober and Isaac (2012) are deficient with respect to their application to the proposed new certification regulations, and he provided some criticisms. The purpose of this response is to address these criticisms.
