Are the leading edges of the horizontal stabilizer designed to be heated?

The leading edges of the horizontal stabilizer are not designed to be heated. This is because, unlike the wings, which often require anti-ice or de-ice systems to prevent ice accumulation and maintain aerodynamic efficiency, the horizontal stabilizer typically does not face the same level of ice formation concerns. Most aircraft designs take into account the airflow patterns and the operational roles of the stabilizer, leading to the conclusion that in normal conditions, additional heating is unnecessary.

While some aircraft may have leading edge devices on wings that require heating systems for safety at low temperatures, the same considerations do not generally apply to horizontal stabilizers, as their function and exposure differ significantly. This distinction is important in aircraft design for weight savings and efficiency, as heating systems can add complexity and weight, which manufacturers often aim to minimize wherever possible.
