Title: Describe aircraft anti-icing and de-icing.
Course: Aircraft Pilot Training II (20053-II) > Section: Understanding Aircraft Systems

Description should include the concept that aircraft ground de-icing and anti-icing procedures serve three purposes:

- Removal of any frozen or semi-frozen moisture from critical external surfaces of an aircraft on the ground prior to flight, referred to as the clean wing concept
- Protection of those surfaces from the effects of such contaminants for the period between treatment and becoming airborne
- Removal of any frozen or semi-frozen moisture from engine intakes and fan blades and protection of external surfaces from subsequent contamination prior to takeoff

Refer to AC 00-6B for more information.
