4. Rime Ice

a. Rime ice is a white-colored, non-transparent, accumulation of ice particles that has a rough
surface.

b. Rime ice is formed by instantaneous freezing of small supercooled er drops when
they contact exposed aircraft surfaces. This us freezing causes a large amount of air to be
caught in The air gives the ice its white non-transparent color, and makes it easy to break.
Rime ice usually forms on the front edge of a structure and extends forward into the airflow.
that takes the shape of the structure. It does not usually form in a layer The fast-freezing rime
ice is kely to accumulate in temperatures between -10 C.

c. Rime ice is most frequently encountered in stratiform clouds, and is so common in
cumulus type clouds at temperatures bel C. e primary danger from rime ice is the change it
