"Rime ice forms when supercooled water liquid droplets freeze onto surfaces. Meteorologists distinguish between three basic types of ice forming on vertical and horizontal surfaces by deposition of supercooled water droplets. There are also intermediate formations. • Soft rime is less dense than hard rime and is milky and crystalline, like sugar… " - Hoar frost aircraft

NettetFreezing Fog will leave only a thin film of frost or rime ice on an aircraft, which nevertheless needs to be removed before flight with a de-icing treatment. Aircraft should also receive an anti-ice treatment before commencing a take-off if freezing fog conditions exist for the taxi and take-off phases of flight in order to prevent further build-up of ice.
