The term "Fly-by-Wire" is an electrically-signaled only control system. However, the term is generally used in the sense of computer-configured controls, where a computer system is interlinked between the operator and the control surfaces. This changes the manual inputs of the pilot in accordance with control parameters. They are carefully developed and validated in order to produce maximum operational effect without compromising safety.
By using electrical control circuits combined with computers, designers can save weight, improve reliability, and use the computers to mitigate the undesirable characteristics mentioned above. Advanced modern fly-by-wire systems are also used to control otherwise unstable fighter aircraft. I think "Fly-By-Wire" is a very successful technology that is used these days in order to aid in flying an aircraft. However, I believe that with the introduction of more sophisticated computers and IT systems, we could really help improve this technology in terms of reliability and safety.

This article is absolutely correct. Although fly by wire can be more efficient, it raises the question of reliability towards the applications used in order to operate the movements of the aircraft. In the past, flight controls have been operated by hydrolic systems which is a completely different system to the aircrafts of today. However, since it is electronic, security is a major concern for many airline companies because there might be unknown errors within the computer systems itself and thus, can lead to a disaster on board. So to what extent can fly by wire is reliable and trustworthy to mankind is the question we should answering ourselves. In contrast, this new technology improves can enhance the control system. As seen today, autopilot and automatic landing system had reduce the amount of pressure on pilots. In conclusion, passengers can trust fly by wire but only to a certain point because there are some disadvantages of it that can raise issue such as safety.

Fly-by-Wire is a more reliable source and systems to changing aerodynamic conditions. This can occur to flights computing, in such situations as by tailoring flight control surface movements so that airplane response to control inputs is consistent for all flight conditions.Furthermore putting circuitry between pilot and aircraft can enhance safety; for example the control system can prevent a stall, or can stop the pilot from overstressing the airframe.
Alls that a fly-by-wire does, is replace the enforce of the physical control of the aircraft with an electrical interface.
Fly-by-Wire is a very indeed a successful idea and consideration to flights and electrical systems.

A fly-by-wire system literally replaces physical control of the aircraft with an electrical interface. The pilot's commands are converted to electronic signals, and flight control computers determine how best to move the actuators at each control surface to provide the desired response. Those actuators initially are usually hydraulic, but electric actuators have been investigated.

Fly by wire baisically is an electrical signaled control system. The term is used when discussing computers usually, it means configured controls where a computer system is interlinked between the operator and the control surfaces. This changes the manual of the pilot together with the control parameters, they are developed to produce maximum operational effect without compromising safety.
By using these types of circuits with computers, designers can save weight and improve reliability and use the computers to designate the undesirable characteristics mentioned above.

This is not an article is basically defining what a "Fly-by-Wire" is and what it is used for and is also like a story.The use of electrical signals to connect the pilot's control devices with the aircraft control surfaces; or the use of electrical control connections with no mechanical backup linkages and providing the pilot direct control of aircraft motion rather than control surface position.an aircraft flight control system that has electronic rather than mechanical controls.

" Fly-by-wire " is an Electrical control system used in Aircraft. and in this article it brings up the fly-by-wire issue , I agree wih the Article.. alothough " fly - by - wire " is efficient but is it really relible ? thats the main question brought up in this article weather its realible to Operate the Movements of an Airplane, so can we really go from Manual to Digital ? or from Physical to electrical.

Fly-By-Wires is a system applied for aircrafts that turned the way they are used from a Mechanical and hydraulic flight system to computer and electrical linkage. This is a huge improvement for plances since the mechanical and hydraulic system is heavy and requires careful routing of the plane's system. The Fly-by-wire system changed that so the plane could automatically adjust its flight system and aeorodynamics to the flight conditions so that all planes using the fly-by-wire system could move at a constant speed and not be affected by the weather.

This is an improvement on reliability in lots of area as the planes are much safer to fly in and even if the computerized system fails, there is a backup hydraulic system that can be used for emergency. In addition, flights would arrive in time with no delays.

Fly-by-wires is basically a technological change from a manual to a digital or electrical system.

Fly-by-wires is a system used in aircrafts and is an electrically signalled only control system. This has raised a few questions, prodominantly reliability questions. Since it is run by computers, there is a chance of a problem occuring in the mainstream that could lead to fatal accidents happening on board the aircraft.
Despite that it has certainly made our lives a lot easier and airtravel is much safer than it was 30 years ago.

Aircraft flight control systems consist of flight control surfaces, the respective cockpit controls, connecting linkages, and the necessary operating mechanisms to control an aircraft's direction in flight. Aircraft engine controls are also considered as flight controls as they change speed.

Fly-by-wirse is an electronically signaled airflight control system. The system is mainly digital which means that it uses a number of different sensors in order for it to function properly.

The effect on society here is that it's easier for a pilot to control a plane, and therefore more people are able to become pilots.

However it creates the problem of over reliability of the system. The passangers of the plane may feel insecure as they may not trust that the system is reliable.
