Describe aircraft anti-icing and de-icing.

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.
