787 Yoke Or Stick?

Sun Feb 27, 2005 1:30 am

Anyone have the skinny on whether Boeing is going to retain the center control yoke configuration in the cockpit on its new bird or go the way of Airbus and install a side stick?

Conventional yoke with FBW as on the 777 as far as I know.

Confirm... it will be a yoke.

Rockwell Collins has already been contracted the flight control systems. There will not be provisions for both.

The most-overlooked difference between (at least the Airbus implementation of) sidestick control and yoke control is the control logic. The visible hardware is by far the least important aspect of it.

And it would be rather expensive to certify two fundamentally different control philosophies for the same airframe, so neither Airbus nor Boeing should be expected to ever offer both conventional deflection-proportional logic (with yoke) and abstracted force-control logic (with sidestick) alternatively.

Boeing might switch at some time in the future, but apparently they´re not there yet.

I hope they never switch. I much prefer a yoke to a sidestick. Call me old fashioned.

N766UA: I agree Yokes seem much better.
But sidesticks make the cockpit so much bigger. As in more space for papers laptops, even food.

Boeing & Yoke go along great  Big thumbs up

Yeah, it does free up a little more space but... I dunno.. I can just see there being a problem and me using 2 hands to yank a tiny stick 2 inches versus actually being able to use 2 hands and have so much more travel and feeling for control. I know it doesn't make a difference as far as actual force being exerted on the control surfaces but, at least I could feel like I'm doing some good versus playing a video game. It's just a better feeling of control to be able to put 2 hands on a yoke if needbe.

I think you´re missing the point: The sidestick is not a 1:1 replacement for a yoke; It´s just a superficial difference on top of a very different flight control logic with a significant number of differences between the two.


The mechanical interface doesn´t say more about the control logic than the form of the mouse you´re using could tell about the applications on your computer.

Yeah but I'm just looking at the yoke versus a stick... I'm not gunna even get into control logic and all that.

But the difference between the two kinds of interface hardware is simply meaningless without the control logic behind it which does the actual translation of your commands.
