Aircraft technology has been constantly under refinement since the first successful flight. Fly-by-wire is the complete replacement of the mechanical linkages between the pilot's stick and the control surface actuators by electrical signal wires, which offers a convenient and logical solution to many of the control system problems associated with modern high performance aircraft and aerospace vehicles. However, there exists a strong reluctance on the part of both pilots and flight control system designers to remove all flight control cables and mechanical linkages and rely solely on electrical signals and electronic devices (Sutherland, 1968). The purpose of this paper is to assess the fly by wire system, with reference to previous flight control

The Hydraulic control system has encountered problems in the past and one of which is the Delta Airlines Boeing 757-200 flight B752 from Los Angeles, CA to Detroit, MI. The crew on board requested to level off at 5000 feet reporting a hydraulic malfunction and the aircraft returned to Los Angeles where the tower reported that they could see both main gears but weren’t sure about the nose gear, the nose landing light was in place however, the landing gear doors appeared wide open. The airline reported the aircraft to have a hydraulic issue. This explores one of the problems that can occur to hydraulic control systems without other forms of backup whereas on a Fly By Wire aircraft there would be multiple forms of backups if the electrical signal was to …show more content…
This is due to the improvement in safety of the aircraft. Within a military aircraft the fly by wire system introduces carefree handling by providing angle-of-attack control and angle-of-sideslip suppression which lead to automatic protection against stall and departure, and by the automatic limiting of normal acceleration and roll rate to avoid overstressing the frame. This means that the pilot and aircraft are protected from any inadvertent pilot control commands that exceed the aircrafts limits (aircrafts structural or aerodynamic limits) whereas in the Hydraulic system the pilots input into the system were not monitored and as a result this led false maneuvers to take place, which caused fatal stalls in fighter jets. As such it can be understood that the Fly by Wire system has proven to be a great advancement through prohibiting controls inserted by the pilot that exceed the flight envelope reducing
