Topic: Are The Next-generation 737's Fly-by-wire?

Hi,

I have a flight in about an hour with Ryanair who fly the Boeing 777-800 aircraft and was just wondering (am a bit of a nervous flyer) if the aircraft are fly-by-wire or like the older generation Boeing 737's using cables etc.?

Any info welcome.

Many thanks,

Pierre.

They are not fly-by-wire. They use basically the same control arrangement as the older 737s.

I guess you mean B737-800 & the first line is a typo.
As mentioned the B738 is Not Fly by wire.
Just curious what was your concern if it was FBW?

Hi,

Just to say merci for the info. Was just curious mainly. I guess both systems are pretty much failsafe but I must admit I'm pretty nervous about everything(!)

Many thanks,

Pierre

The 737 uses steel cables that run from the flight deck to various control valves and components. All critical systems use cables, rudder, elevator, ailerons, flaps, spoilers, landing gear, brakes, etc. The 737 is one of the few commercial jets still made where in the event of a complete hydraulic loss, the pilot can still fly the plane using the control wheel and applying forces that translate directly into aileron and elevator movement. A cable driven system is adequately reliable and safe to use. History has shown it to be very reliable. It is interesting because airplanes are often very low tech. When you look at features like hydraulics and flight controls, most of the designs have not changed over the decades. Using well tested designs that designers have experience with has proven to be cost effective and safe.

The 787 will be Boeing's first ever exclusively fly by wire commercial airplane. The 777 is fly by wire, but kept a couple systems as cable driven. The 787 will be first to have everything exclusively by wire. The 747-8 will have an interesting hybrid with a few of the systems going to fly by wire, but not the entire control system.

It appears you lived to tell about it based upon the time difference between your two posts.

Congratulations!  champagne   champagne

And on that note, there is really no need to continue this topic.
