dent who has flown Chinook helicopters in Italy, Korea, Alaska, and throughout
CONUS, moderate icing builds very quickly and can be very disconcerting
without deicing capability. Another points out that because there is no working
deice system on AH64 helicopters, he has little actual flight experience in icing.
With four exceptions, commanders rated the icing hazard warning on a par
with improved icing forecast. Two exceptions are commanders with the 11th
Aviation Brigade in Illesheim, Germany; the commander of the 11th Aviation
regiment considered that an icing hazard warning would more significantly affect
his mission (moderate vs. low impact), while the commander of the 2-6 Cavalry
Squadron (Attack) regarded an improved icing forecast as being more significant
(high vs. moderate impact). The other two exceptions are the HQ, 17th Aviation
Brigade in Seoul, Korea, which returned the commanders' questionnaire twice,
completed by different individuals. One commander at the 17th Aviation Brigade
rated an improved icing forecast as having high impact on his mission, while
rating an in-flight icing hazard warning as low impact; the second commander
rated the two technology advances exactly the reverse, i.e., the icing forecast as
low impact and the in-flight icing hazard warning as high impact.
Table 15. Commanders' ratings (by location) of potential impact on mission of an
icing hazard warning system in-flight with cockpit display.
