Campus: Camperdown/Darlington
Pre-Requisites: AERO3560 AND AMME3500.
Brief Handbook Description: This unit aims to develop an understanding of aircraft flight test, validation and verification, and the development of modern flight control, guidance, and navigation systems. Students will gain skills in analysis, problem solving and systems design in the areas of aircraft dynamic system identification and control.

At the end of this unit students will be able to understand: the principles of stability augmentation systems and autopilot control systems in aircraft operation, their functions and purposes; the characteristics of closed loop system responses; advanced feedback control systems and state-space design techniques; the concepts of parameter and state estimation; the design of observers in the state space and the implementation of a Kalman Filter; multi-loop control and guidance systems and the reasons for their structures; flight test principles and procedures and the implementation a flight test programme.
Assumed Knowledge: This Unit of Study assumes that AERO3560 Flight Mechanics 1 and AERO4560 Flight Mechanics 2 (or equivalents) have been successfully completed.
Additional Notes: Note that not all of the listed topics will be covered. Topics will be selected and delivered subject to the interests of the class and rate of progress with the major project.
