Clear ice typically forms in outside temperature ranges of what?

Clear ice typically forms when supercooled water droplets freeze upon contact with an aircraft's surface. This process usually occurs in a temperature range where the atmospheric conditions support the presence of supercooled liquid water, which is often found in clouds or precipitation. The correct temperature range for the formation of clear ice is approximately 0 to -10 degrees Celsius. This range allows for liquid water to exist in a supercooled state, which is crucial for the formation of clear ice upon freezing.

In contrast, other temperature ranges listed may not adequately support the presence of supercooled droplets or may lead to the production of other types of ice, such as rime ice, which forms differently under colder conditions. Understanding these temperature dynamics is essential for pilots and dispatchers in order to manage the risks associated with aircraft icing.
