T&E 4103 Flying Qualities Flight Testing I

Course Description

An intensive development of the methods used to determine the static stability of fixed-wing aircraft and the implications of incorrect levels. Subjects include the regulatory requirements and flight test techniques involved to determine the longitudinal, lateral, directional, maneuvering, and flight path stability of single and multi-engined aircraft. Included is an introduction to mechanical flight control systems, Mach effects and roll performance.

Anticipated Student Academic Outcomes

Be familiar with
1. Mechanical flight control systems.
2. Aircraft trim systems. 
3. Mach effects on stability and control.

Understand
4. The practical importance and associated regulatory requirements of each type of stability.
5. The “big picture” of flying qualities evaluation.
6. How to determine the engine-out capability of an aircraft using flight test techniques.
 
Know
7. How to determine the longitudinal static stability of an aircraft using flight test techniques.
8. How to determine the maneuvering stability of an aircraft using flight test techniques.
9. How to determine the lateral-directional static stability of an aircraft using flight test techniques.
10. How to determine the flight path stability of an aircraft using flight test techniques.
