Question

Why is the BFW system used?

(a) To control aerodynamically efficient but unstable body

(b) For communications in aircraft

(c) Better navigation

(d) Reduced chances of enemy detection

I have been asked this question in semester exam.

I want to ask this question from Fly-By-Wire Technology in section Fly by Wire Flight Control of Avionics

Answer 1

The correct answer is (a) To control aerodynamically efficient but unstable body

Easy explanation: The literal meaning of Fly By wire system is flying by wires(I.e; electrically). One of the main advantages of using FBW is to exploit increased aerodynamic shapes at the cost of stability. The FBW system provides high integrity automatic stabilization to compensate for the loss of stability and provide overall better performance.
