Which areas of an aircraft need to be protected against ice accretion?
  • A
    Aircraft nose, AOA vane, and APU inlet.
  • B
    Temperature probe, air conditioning inlet, and windscreens.
  • C
    Tail leading edge, static ports, and ram air inlet.
  • D
    Wing leading edges, engine intakes, and pitot probes.

Refer to figure.

Ice control systems consist of a combination of anti-icing and de-icing equipment. Anti-icing equipment prevents the formation of ice, while de-icing equipment removes ice after it has formed. Aircraft components that must be protected from ice accumulations include the leading edges of wing and tail surfaces, pitot and static source openings, fuel tank vents, stall warning sensors, windshields, and propeller blades. Additionally, engines can require alternate sources of intake air or ice protected inlets.
