Types of Icing on Aircraft

This is not the kind of icing on your favorite chocolate cake. This is far more dangerous. Icing on the surfaces of wings, elevators and rudders can completely ruin a pilots day, if not his or her entire life. Here are the three types of icing that can occur:

  • Rime - Milky, rough and opaque ice. It is usually caused by supercooled water droplets freezing when they contact the aircraft.
  • Clear - Clear (duh) and typically smooth ice . It is generally caused by larger drops of supercooled water freezing when they contact the aircraft.
  • Mix - A mix of rime and clear icing.
