Abstract: Icing is among aviation's most serious
cast or actual in-flight icing. The common notion,
weather hazards because it renders aircraft unfly-
however, is that icing is "not a problem" for Army
able before flight and severely reduces aircraft
aviators because they generally "do not fly in ic-
performance within flight. Army aviation is vulner-
ing." This report assesses the effects of icing, both
able to icing, which occurs most frequently at low-
before and during flight, on the ability of Army avi-
er altitudes, and which generally has the greatest
ators to accomplish their mission. Interviews with
impact upon small fixed-wing aircraft and helicop-
aviation commands, surveys to aviation com-
ters that fly slowly and low. Icing causes mission
mands worldwide, and assessment of Army avia-
delays during ground deicing of aircraft and mis-
tion safety records demonstrate the affect of icing
sion cancellations and abortions because of fore-
and snow on Army aviation.
