Anti-ice and Deice Systems for Wings, Nacelles, and Instruments

Abstract

The need for anti-ice or deicing systems did not show up during the first one and one-half decades of the aviation industry. These early aviators did not fly high enough or during foul weather to enter icing conditions. However after WWI, planes started entering icing flight conditions, and the schedule demands of commercial aviation created a need for deicing systems. This chapter describes the present systems used to deice vital aircraft surfaces and how they operate to prevent ice buildup, including hot engine bleed air and pneumatic deicing “boots.”
