Automatic Landing Control System

Approach and landing is the highest risk phase of flight, accounting for over 50 percent of all accidents at every level of aviation. Many types of accidents can happen during the approach and landing phase of flight. Because of its inherent risk there have been many international efforts addressing the approach and landing phase of flight. These efforts have primarily addressed the highest risk areas such as CFIT and runway excursions. They have addressed all aspects of approach and landing accidents, and in addition they also addressed all the responsible parties involved with reducing the risk of approach and landing accidents. These parties include the aircraft manufacturers, aircraft operators, aircrews, air traffic management, regulators, and airports. Many interventions have been created to assist in reducing the risk of accidents in the approach and landing phase of flight. Some instruments can be used to land the aircraft in limited visibility by positioning the aircraft relative to a reference trajectory. However, automatic controls are to be applied when the conditions are at the worst. The objective of this project is to devise an automatic landing control system using Model- Following control and HInfinity output feedback control and test it on X-Plane flight simulator.
