With the increase in electronic technology, an idea emerged to create an electronic flight control system. In this electronic flight control system, steel wire and pushrod are replaced by much lighter cables. In addition, with an electronic control system, aircraft engineers are more flexible in determining the configuration, size, and placement of components. This electronic flight control system is what became known as the fly-by-wire system. Meanwhile, if you use this system for your plane but its ball screws are damaged, we recommend you to hire the best ball screw repair service.

Fly-by-wire is an aircraft control system that uses electronic circuits to send control inputs from pilots to motors that drive control surfaces such as flaps, ailerons, and rudders. In this fly-by-wire control system, there is no longer any hydraulic or mechanical connection directly between the pilot and the control surface on the aircraft. Digital fly-by-wire (DFBW) uses an electronic flight control system that is paired with a digital computer to replace a conventional mechanical control system.

By adding a digital computer between the pilot and the aircraft, so many benefits are obtained. Fly-by-wire makes the aircraft lighter because it has eliminated many hydraulic mechanical systems. In addition, the aircraft also has better maneuverability because computers can adjust aircraft’s attitude hundreds of times better every second than humans. This makes the plane’s passengers can fly more gently and better fuel efficiency. On military aircraft, fly-by-wire makes the aircraft more resistant to battle damage than conventional control systems. Fly-by-wire also requires less maintenance than its predecessor flight control system.

The fly-by-wire control system was built to interpret the pilot’s wishes for control and then translate it into actions that occur on the control surface of the aircraft, where the transfer process also involves environmental factors. In a conventional control system, when the pilot pulls the control column the elevator flap rises proportionally to the extent to which the pilot pulls the control column. Whereas in fly-by-wire control systems, flap elevator movement is generally also proportional, but computers can make adjustments if the turbulent environment occurs. The ratio between the control column in the pilot’s hand and the flap motion on the wing is not 1:1, this is no longer a direct connection.
