What is the three axis redundant flight control system?
Speak plainly, "three axis 4-redundancy" is to use a computer controlled aircraft, that is no longer used mechanical lever, and the pure digital FBW system.
The active control system of three axis redundant digital / telex: the so-called three axis is the axis, roll and yaw axis, this refers to the three digital channel and a standby channel simulation.
The "telex operating system" is the Chinese free translation of the English "Fly by wire control system" (FBW), also known as the flight line manipulation system". It is an advanced electronic flight control system. A typical telex control system is composed of sensors (gyroscopes, accelerometers and other various inertial measurement devices and sensor measurement device of atmospheric angle), input device, flight control computer, steering gear and electric transmission line. The fly by wire system was originally developed to solve the stability of aircraft.
