What is “Fly-by-wire” technology in aviation? What benefits does it have and why is it used in modern airplanes today?
In: Engineering
Fly by wire or drive by wire simply means a mechanical component of your car or plane is controlled by an electronic device rather than mechanically.
For example, throttles in cars used to have a physical cable that ran from the pedal to the throttle body, when you pushed the pedal down the cable tightened up and opened the throttle body to let more air and fuel in (speed the engine up).
Drive by wire on the other hand means the press the gas pedal down, an electronic signal is sent to the throttle body, and a servo motor in the throttle body actuates to open it.
