The paper discusses the fly by wire technology in aircraft that has replaced the manual flight control with electronic controls. The paper describes the features of fly-by-wire technology and relates that an aircraft designed with fly-by-wire technology is way lighter than an aircraft with a similar design based on conventional manual controls. The paper also discusses how fly-by-wire flight control systems eradicate the intricacy and the weakness of the mechanical circuit of the hydro-mechanical or electromechanical flight control systems. The paper addresses the differences between a digital and analog fly by wire system and discusses the main concern with the digital fly by wire system that is reliability.
From the Paper:"Fly by wire is a new technology in aircrafts that has replaced the manual flight control with electronic controls. In this technology the flight control signals are converted into electrical signals which are transmitted to the processors through electric wires and the computer determines the movement of the actuators according to the control command (Crane 2002). Moreover, this system sends out certain commands to the computer without any input from the pilot, these commands are mainly transmitted for a more stable flight. The fly-by-wire system also allows automatic signals sent by the aircraft's computers to perform functions without the pilot's input, as in systems that automatically help stabilize the aircraft.
"Mechanical and hydro mechanical flight controls system comprise of all heavy steel cables, metallic pipes with hydraulic fluid, cables and pulleys which adds to the air craft total weight thus slowing it down and decreasing its full efficiency. Both systems frequently need unnecessary backup to tackle mechanical failures, which further increases weight. Additionally, both have inadequate capability to adjust to changing aerodynamic conditions. Dangerous maneuverability such as stalling, spinning and pilot-induced oscillation (PIO), which is dependent chiefly on the strength and configuration of the aircraft concerned rather than the control system itself, can still occur with these systems (Crane 2002)."
