If I close my eyes, I can picture the outline of an airplane against the glowing fog in the background created by hangar lights on the other side of an icy ramp in North Dakota. I can feel the cold air on my face and imagine the steam exhaled from my mouth. You may have a similar memory.
I can also see the pristine white Canadian fields, blanketed by snow and the slushy centerline of the runway at International Falls Airport. I remember the waves of anti-ice fluid flowing back along the wing, and I can almost feel the difference in force required to rotate the aircraft.
Those two memories are just the tip of the proverbial iceberg, the host of memories of cold weather testing, and this edition covers some of those topics in A Limited Survey of Cold Weather Flight Test Safety - Three introductory observations about Cold Weather and Flight Test, which flows right into the next features: Sample of Cold Weather Flight Test Safety Papers, and an account of Lockheed F-117 Cold Weather Testing.
