FBWjärjestelmää

FBWjärjestelmä, which translates to Fly-by-Wire system in English, is an aircraft control system that replaces conventional mechanical linkages with electronic signals. In a traditional aircraft, control surfaces like ailerons, elevators, and rudder are moved by physically connecting the pilot's controls to them via cables, pulleys, and pushrods. An FBWjärjestelmä utilizes computers to process pilot input from the controls, such as a joystick or sidestick, and then sends electrical signals to actuators that move the control surfaces.

This system offers several advantages. It allows for the implementation of flight envelope protection, which prevents the aircraft from exceeding its structural or aerodynamic limits. This can enhance safety by preventing stalls or overspeeds. FBWjärjestelmä also enables more precise and responsive control, as computers can fine-tune the response to pilot inputs. Furthermore, it can reduce pilot workload by automating certain control functions and providing artificial feel to the controls, mimicking the feedback that would be present in a mechanical system. The removal of heavy mechanical linkages can also contribute to weight savings in the aircraft. Many modern commercial airliners and military aircraft employ FBWjärjestelmä.
