Aircraft Feature; Fly-By-Wire Technology 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).
