Why does the tailplane collect more ice than the wings of an aircraft?

• A. The tailplane is located at a higher altitude
• B. The tailplane has a thicker surface
• C. The tailplane presents a thinner surface to the airstream
• D. The tailplane operates at a different angle of attack

Answer: (C)

The tailplane, or horizontal stabilizer, tends to collect more ice than the wings primarily because it presents a thinner surface to the airstream. This area is often positioned such that the airflow around it is affected differently compared to the wings. The wings generate lift and are designed to have a particular profile that helps smooth the airflow over a larger surface area, whereas the tailplane’s profile and position can lead to a more turbulent flow around it, which may contribute to ice accumulation under certain conditions. When the air moves over the tailplane, it does so at a lower velocity than over the wings due to the design and aerodynamic characteristics; this can lead to a higher local pressure, allowing for greater ice buildup in specific scenarios. Additionally, the downward force generated by the tailplane impacts the overall lift and the airflow characteristics around it, exacerbating the conditions conducive to ice forming. In contrast to this, the other choices do not accurately account for the mechanisms involved with ice accumulation on the tailplane. The tailplane’s altitude or thickness doesn't play a crucial role in its propensity to collect ice, and operating at a different angle of attack pertains more to aerodynamic performance rather than the specific factors influencing ice accumulation in winter operations.
