rate how a 50% reduction in flight cancellations due to improved forecast icing
would affect their mission, 80% of the commanders indicated it would have
either a moderate or high impact on their mission. One commander with flight
experience in the United States, Germany, and Korea stated that the forecast level
of icing is rarely accurate for rotary wing aircraft. The support for an improved
icing forecast is strong (rated moderate or high impact) everywhere except with
the SHAPE flight detachment in Belgium and with a minority of commanders in
Germany and Korea (Table 14).

The support for an in-flight icing hazard warning system is strong (rated
moderate or high impact) everywhere except at the SHAPE flight detachment in
Belgium and with a minority of commanders in Germany and Korea (Table 15).
Lack of experience with flying in icing conditions intensifies any problems; one
commander refers to "apprehension of the unknown." As noted by one respon-
