Course Description

An intensive overview of the theory and test procedures to evaluate helicopter dynamic stability, controllability, low speed flight characteristics, and ground handling.  Subjects include analysis of helicopter dynamic motion, airworthiness certification requirements and flight test techniques for dynamic stability and low speed flight, automatic flight control systems, ground handling test methodology, and closed-loop handling qualities testing.  (Prerequisite: Satisfactory completion of T&E 4113)
