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.

An apparatus for attaching a load bearing line to a helicopter is disclosed that utilizes a curvilinear track mounted on the underside of the helicopter with a carriage having a cargo hook freely movable thereon. The curvilinear track has a radius of curvature that extends from the center of gravity of the helicopter to maintain forces imposed on the helicopter from a swinging load directed through a point near the center of gravity of the helicopter.
