Title: Describe aircraft anti-icing and de-icing.
Course: Aircraft Pilot Training II (20053-II) > Section: Examining Atmospheric and Meteorological Conditions

Description should include the following:

- 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
  - 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
