ICE CONTROL SYSTEMS
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.

• The pitot tube and static port openings, fuel vents and stall warning sensors, typically contain electrical elements to prevent ice formation. These elements can be checked during a pre-flight inspection by touching each component when the heat is on.
