Most conventional aircraft were created to be flown by human pilots. This affects the fundamental design configurations of aircraft and their handling qualities. In this anthology talk, we first look at various flight control examples where we could learn from human behaviour to create simple, safe and effective flight control systems for conventional aircraft. We also see how conventional aircraft can be extended to improve their performance by relying on unconventional approaches. Eventually this line of thinking leads us to creating unconventional high performance and energy efficient aircraft. This talk is suited to an unconventional high performance and energy efficient aircraft. This talk is suited to an audience with a general control systems background, including graduate students of various engineering disciplines, with an interest in the fundamentals and practical qualities of flight stabilisation and control algorithms.
