Abstract

The invention relates to a fly-by-wire system which comprises: three-stage piloting control (4), each stage including a control computer (16, 18, 20) suitable for determining the positions of the stick, and a monitoring computer (22, 24, 26) capable of verifying all the pre-determined positions of the stick; three-stage control-surface position calculation (6), each stage including a control computer (40, 42, 44) suitable for calculating the control-surface positions from encoded positions of the stick, and a monitoring computer (46, 48, 50) capable of verifying all the calculated control-surface positions; a single unidirectional communication link (88) connecting the control computer (16) of the first piloting control stage to the control computer (40) of the first control-surface position calculation stage; a single unidirectional communication link (132) connecting the control computer (18) of the second piloting control stage to the control computer (42) of the second control-surface position calculation stage; and a single unidirectional communication link (142) connecting the control computer (20) of the third piloting control stage to the control computer (44) of the third control-surface position calculation stage.

Description

technical field [0001] The invention relates to an aircraft fly-by-wire control system. Background technique [0002] Fly-by-wire systems are gradually being applied to more and more aircraft. The first fly-by-wire system was replicated with a mechanically controlled manual backup system, enabling manual landing in the event of a fly-by-wire system failure. However, such manual controls are bulky and heavy, so manufacturers today no longer design aircraft that include such manual backup controls. [0003] In this light, it is important that fly-by-wire systems have a high level of safety. To guarantee this level of security, redundant processors are implemented and communication links are duplicated. [0004] E.g, figure 1 A known fly-by-wire system is shown in . It comprises a pilot control device 100, a position calculation device 102 of a flight control surface, and an actuator control device 104, said pilot control device being suitable for determining the position ...
