![]() Stick shaker and artificial feedback are the methods to replicate the aerodynamic forces acting on the control surfaces to the cockpit control. With hydro-mechanical system, the aerodynamic forces acting on the control surfaces are not felt by the pilots making it easy to controls. This system utilized cables, pulleys, and gears at the cockpit control and hydraulic system consist of pipes, reservoir, valves and pumps at the control surfaces. Hydro-mechanical control system is a system which mechanical linkages are connected to the hydraulic system. By using hydraulic systems, aircraft can fly faster due to the pilot does not have to put extra effort to move the control surfaces with increasing aerodynamic forces. ![]() This is when hydraulic systems plays an important role in aircraft control system. Aircraft needs to fly faster, carry more payload and strong. With new emerging technology and war at that time, air superiority has become an advantage. Early aircraft were lightweight and the aircraft can only fly at a slower speed thus aerodynamic force is not strong making it possible to manoeuvres the aircraft. By using the cables and pulleys, every forces act on the flight control surfaces are being transmitted to the cockpit control and felt directly by the pilots which they have to counter these forces using their own strength without any assistance. This cables and pulleys act as pull and push system to move the flight control’s surfaces at the expense of the pilot’s effort. It is known for its properties which is lighter than standard copper wire, able to carry multiple signals in single cable, no electrical current involved in the cable, cheaper than copper cable because it is made from silica (glass), and does notĪt the early stage of aviation, aircraft utilized cables and pulleys for controls also known as mechanical linkage. ![]() ![]() Fibre optic cables are widely used in telecommunication and network. ![]()
