What is the primary purpose of de-icing an aircraft?

The primary purpose of de-icing an aircraft is to remove ice, snow, or frost from its surfaces. Accumulation of these substances can negatively impact the aircraft's performance, including its lift and ability to control effectively during flight. Ice or frost can alter the shape of the aircraft's wings and control surfaces, leading to dangerous flight conditions. By ensuring that these surfaces are clean and free of frozen deposits, de-icing plays a critical role in maintaining the aircraft's safety and operational efficiency during takeoff and flight. This process helps to ensure that the aerodynamic properties of the aircraft are preserved, enabling it to perform as designed while minimizing the risks associated with ice and snow build-up.
