LOL, seriously? You've clearly never piloted an aircraft or worked on one. Did you stay at a Holiday Inn last night?
Lets see now..
Fly by wire, simply means they don't fly by cables anymore. It is kinda funny to think of a big airplane like that where the pilots have no direct connection to the control surfaces.
So F-b-W is replacing all those brute force, control cables hookups to the yoke and pedals, for the pilot to get a real workout on. Now, it is signal wires and power actuators.
Instead of honking into a turn physically, we ask nicely through control moves that are not pulling actual control cables back and forth. Cable are single point failure modes. F-b-W is set up in redundant systems.
Our little moves tell the computer to do little moves, our big moves command big moves, but, no giant, Oh No!!!, back pressures to our hands and feet.
The ONLY time an aircraft will provide control feedback is if you are in an airliner that is about to stall. It will shake the stick. All other indicators come in the form of lights and sounds. If you slam the stick on an Airbus full left, the plane will bank 15* and stop and hold. It will never push back. You can hold it there all day long and never get tired.
In fact it is more than eliminating the strength required to fly big planes.
Yeah, see, planes have balanced control surfaces and are all quite easy to move no matter their size or how your controls are linked, be it torque tubes or steel cables. If you can push a 1lb weight around you can operate the controls of any aircraft. If you can't during preflight, you don't take off. I know a flight instructor that has his students land a few times using nothing but trim controls and throttle.
There are planes now, not commercial, military fighters that are designed to be so nimble they are "dynamically divergent."
This has been the case longer than it hasn't. Negative stability is a side effect of being so maneuverable. It means that the plane will continue to execute a control input even after you've let go of the control. Neutral stability would maintain the last input control, and positive stability will return the aircraft to level flight. Fighters have always had negative stability, this is nothing new.
It means the opposite of stable. The 777 is stable and will glide without power.
A 777 without power will glide about as well as a rock. Swept back wings are much harder to control at low speeds, and they also increase your stall speed. If you can't maintain a good airspeed, you will stall in no time and simply fall from the sky. This means you have to dive and you only have so much altitude to work with. It's a jumbo jet, not a Super Cub.
But, many planes now, cannot be flown by hand. The computer considers what the warfigher is asking, and the computer is capable of rendering the pilot unconscious if the moves are too abrupt. She does not want that.
Many planes now (fighter and commercial), with the exception of 99% of them in service today.
So, even in the heat of it, the airplane is guarding the pilot and doing the flying. She takes the commands and does something airworthy with it. She ignore commands that would rip off the wings and/or knock out the pilot, with GLOC. Gee induced Loss of Consciousness. If the pilot does go out, his ship eases up the gees and levels off.
Are you talking about fighters again? Because if this is true, it's new. The last thing you want in a fighter is a computer overriding your control input. Are you telling me that if a fighter is pulling out of, say, a loop, and the G meter triggers the plane to stop pulling up, it's going to crash him into the ground? I find that pretty hard to believe. You would never allow a computer to control a plane in these roles. Passenger planes? Sure. Fighter jets and aerobatic planes? I don't see that happening. I think it would cost more lives than it could save. The whole point in these platforms is to give the pilot complete control. So what if you input a command that rips the wings off? If you wanted a safer plane, you'd be in an airliner flying straight and level not in a fighter jet.
These computers all have female voices.
People listen better to females. A Fact.
That is the State of the Art, of Fly by Wire. It makes maintenance at once more easy for many things and more complicated for back at the shop calibration stuff.
Yeah, because yanno, trouble shooting 3 miles of wiring, electrical actuators and relays is way easier than inspecting a steel cable and some pulleys. And shop calibration? You mean like adjusting micro switches just as they have done for decades for things like, oh, I dunno.. landing gear, flaps, slats, doors, even some primary control surfaces..
The biggest advantage of a fly by wire system is the weight savings.
You can stop pretending you know what you are talking about now..
P.S. They don't all have female voices either, just most of them.
