Fly By Wire

[Viraaj Shah]

Hello guys,

I hope this question isn't repeated.

Please explain how the ''Fly by wire'' technology works in detail and why is it used. Thanks

It is such a large topic that I doubt someone will type it all up on this thread.......

Try this - Wikipedia (http://en.wikipedia.org/wiki/Fly-by-wire)

The basics are actually pretty simple, manual input by pilot is converted to a regulated signal of voltage that makes it's way usually through a computer to the flight control where that rated voltage tells a valve to open or close.

The actuator on the flight control in return sends back a regulated voltage "based on the electrical resistance of a device that veries with actuator position" back to the computer to verify the actuator is doing what it is told to.

Not the full story, Mud.

You omitted the smoke, mirrors and PFM...

well I dont know why you post it here when it can be easily googled but the simple answer is...
A fly by wire (FBW) system replaces manual flight control of an aircraft with an electronic interface.
