Abstract
A horizontal stabilizer structure for improved stabilizer performance at positive and negative angles of attack is disclosed in which a leading edge slat/spoiler extending lengthwise along the stabilizer is disposed forward and below the leading edge of the stabilizer. The leading edge slat/spoiler directs airflow along the under surface of the stabilizer at negative attack angles and disrupts airflow over the upper surface at positive attack angles.
