The tailplane is the surface of the airplane that tends to accumulate ice the fastest due to several factors related to airflow and the nature of the surfaces involved. The tailplane, which includes the horizontal stabilizer and elevator, is positioned at the rear of the aircraft where airflow can be less turbulent compared to the front surfaces like the wings and windshield. When an aircraft flies through icy conditions, the mixed airflow can cause ice to form more easily on the tailplane due to its relative position.

In addition, the tailplane often has a lower temperature than the wings or fuselage because it is located in the more isolated air stream behind the main wing. This can allow it to reach freezing more quickly when flying in conditions where supercooled water droplets are present.

While ice can accumulate on all parts of the aircraft when exposed to moisture in freezing temperatures, the characteristics of airflow around the tailplane contribute significantly to its tendency to ice up more quickly than other surfaces.
