Answer: Improves control
Explanation: Stealth configurations and requirements can conflict with aerodynamics requirements and FBW flight control is essential to give acceptable control and safe handling across the flight envelope. An example of such is the American fighter F -117, nicknamed “Nighthawk”. It is almost impossible to fly this aircraft without feedback FBW system.
