Finally, ailerons on the rear edge of each wing roll the plane from side to side.Īutopilots can control any or all of these surfaces. When the rudder is tilted to port (left), the craft yaws in the opposite direction. When the rudder is tilted to starboard (right), the aircraft yaws - twists on a vertical axis - in that direction. The rudder is also located on the tail of a plane. The first are the elevators, which are devices on the tail of a plane that control pitch (the swaying of an aircraft around a horizontal axis perpendicular to the direction of motion). To understand this discussion, it helps to be familiar with the three basic control surfaces that affect an airplane's attitude. Advanced autopilots can do much more, carrying out even highly precise maneuvers, such as landing an aircraft in conditions of zero visibility.Īlthough there is great diversity in autopilot systems, most can be classified according to the number of parts, or surfaces, they control. The original use of an AFCS was to provide pilot relief during tedious stages of flight, such as high-altitude cruising. In addition to flight control systems, avionics include electronics for communications, navigation, collision avoidance and weather. An AFCS is part of an aircraft's avionics - the electronic systems, equipment and devices used to control key systems of the plane and its flight. In the world of aircraft, the autopilot is more accurately described as the automatic flight control system (AFCS). The same principles, however, apply to autopilots that control any kind of vessel. Most people associate autopilots with aircraft, so that's what we'll emphasize in this article. Each technique discussed in this book is illustrated by a relevant example.Automatic pilots, or autopilots, are devices for controlling spacecraft, aircraft, watercraft, missiles and vehicles without constant human intervention. The second section discusses some concepts of adaptive and fault-tolerant flight control systems. The first section focuses on a literature review and some recent theoretical developments in flight control systems. This book consists of two major sections. This book focuses on a selection of key research areas, such as inertial navigation, control of unmanned aircraft and helicopters, trajectory control of an unmanned space re-entry vehicle, aeroservoelastic control, adaptive flight control, and fault tolerant flight control. Recent new developments in this field focus on a wealth of different aspects. Even today, many research efforts are made for the further development of these flight control systems in various aspects. Since the early days, the concept of automatic flight control systems has evolved from mechanical control systems to highly advanced automatic fly-by-wire flight control systems which can be found nowadays in military jets and civil airliners. The history of flight control is inseparably linked to the history of aviation itself. Even today, many research efforts are made for the further developmen.
