Every modern aircraft is a complex dynamic system. The flight control of aircraft is an important and difficult technical task. Automatic piloting systems deprive the pilot of the need to perform routine operations, and provide him the opportunity to pay more attention to navigation and piloting.
In the General case, there are following system of automatic piloting :
The interaction of automatic piloting shown in Fig. 135. Management of automatic piloting systems is realized by using the corresponding panels in the flight deck.
The Fly-By-Wire (FBW) system provides control of the position of the plane in the air using mechanical rejected parts (elevators, rudders turn, ailerons, flaps, interceptors.)

Autopilot/Flight Director System (AFDS) - provides automatic control of the flight path of aircraft. It controls the speed, altitude and course of flight of aircraft and ensures adherence to the values of these flight parameters within certain limits by means of connection with FBW.
Flight Management System (FMS)- helps the pilot to perform the navigation function. It indicates the next position of aircraft according to the flight plan for AFDS.
All these systems are controlled by using a large number of sensors, measuring flight parameters Aircraft and reflect them to the pilot through an electronic display.
