Question

How is fly by wire system implemented in an aircraft?

(a) By using control rods and linkages connecting stick to control surfaces

(b) By using high power radio transmitters and receivers

(c) By using computers and actuators to control surfaces

(d) Artificial intelligence

I had been asked this question in my homework.

My question comes from Fly-By-Wire Technology topic in division Fly by Wire Flight Control of Avionics

Answer 1

The correct answer is (c) By using computers and actuators to control surfaces

The best explanation: The fly by wire system uses actuators to move the control surfaces to maintain the stability of an aircraft. The signals sent by the pilot via the control stick is intercepted by the flight controller computer and signals are sent to the respective actuators to move the control surfaces.
