If you say so John but you never present any evidence or reference to back
up your assertions. Small droplets are not a major icing hazard because
they freeze right at the leading edge..

Any time air is accelerated, as it is when passing over a small-radius

While small radius objects do collect ice better than larger redius
objects,
temperature drop has nothing to do with it. Small radius objects have a
higher "collection efficiency" meaning more of the droplets in their
path
will impact the surface. They have a higher collection efficiency
because
they don't project a "bow wave" as far in front of them as larger. You
NEED
supercooled water for airframe icing.

Not exactly. Small objects and small water lead to the best conditions,
from a statistical standpoint, for gathering ice.
