Flight Operations Comments
Experience
4. Some flights cancelled (minimal); missions/mission times adjusted.
6. No in-flight icing experience.
10. I have over 10 years flying the CH47D (+1600 hours). This a/c is poorly
equipped to handle any icing and is limited to light icing only.
12. Icing has little to no impact on operations in central Germany.
20. In-flight/ground. Homestation/Schweinfurt/Kosovo/Bosnia.
28. Icing is almost always prevalent during the winter months in Europe.
Most of our flying is for maintenance test flights. We are mostly restricted by
cloud heights/ceilings for our mission.
38. Occasional icing on windscreen, engine inlet screen, and blade tips.
42a. We are a fixed-wing unit flying at 20,000 plus with deice and anti-ice.
Flights are cancelled in summer months during monsoon season.
44. Several PCs surveyed with at least three years of Fort Drum winters.
[Included copy of 1-10 Avn weekly flight schedule trends.]
45. Have never flown in icing conditions.
46. Typically not a big factor because of our restriction on flying in icing
conditions. If icing is forecasted, the flights are typically (always) cancelled prior
to departure if the icing will affect the profile to be flown.
49. Minimal.
53. Ground icing issues are addressed by our host facility JRB NAS Willow
Grove, PA. We could use portable aircraft deicing equipment. We try to hangar
all of our a/c in winter, but hangar size is limited.
56. Experienced lightmoderate icing during heavier-than-forecast IMC
causing loss of a/c performance. Required ATC to give lower altitude to stop
buildup. Experienced asymmetrical shedding and vibration. Another time, had to
follow another a/c for navigation due to heavy snow and ice accumulation on
windscreen.
59. Do not track missions cancelled or delayed by weather.
60. Do not fly; schedule a/c.
