The purpose of this AIR is to provide a comprehensive description document that displays various examples of transport and business aircraft systems driving Trimmable Horizontal Stabilizers.
The main focus is on mechanical systems which may be actuated hydraulically or electrically. The document is intended as an overview for those specifying or designing Horizontal Stabilizer Trim Actuators in order to compare existing solutions as reference for implementation in new aircraft programs.
Rationale:
There is a need for a general overview of implementation of Trimmable Horizontal Stabilizer Actuators as a source of information both for aircraft manufacturers specifying this type of equipment as for systems suppliers designing them. This document provides this overview and a summary of examples of successful developments to serve as a guideline.
