What is the temperature range associated with Layer Cloud Icing?

Layer cloud icing typically occurs in a temperature range where supercooled liquid water exists within the clouds. This is most commonly found between 0 and -15°C. In this range, droplets remain in liquid form despite being below freezing due to their small size, leading to the potential for hazardous icing conditions on aircraft.

When temperatures are above freezing, there is no risk of icing since any moisture would evaporate. Below -15°C, the likelihood of supercooled liquid water diminishes, leading to a reduced risk of significant ice forming. However, the specific interval of 0 to -15°C is particularly critical for pilots to monitor, as this is where icing conditions can be most severe.

Understanding the temperature ranges is vital for flight safety, as icing can greatly affect an aircraft's performance and handling characteristics. Knowing this temperature band can help pilots make informed decisions regarding flight operations in potentially hazardous weather conditions.
