C Series fly by wire
 
Hi,

I recently watched a short video of a presentation of the C series' cockpit. I noticed that the side stick was equipped with trim switches.
So I wonder with which kind of fly by wire system, especially regarding control laws, this aircraft will be equipped. Does Bombardier follow the Airbus or Boeing approach? Are the sticks connected? Unfortunately I have not found any useful information yet. I only was able to find out that the autothrottle is backdriven...
Could anybody of you shed some light on this topic?

can you give the video to watch?

Boeing (Embraer) ish downstream of the side-stick. The side-stick isn't the same as AB.

pensador,
Here you are.
Bombardier's site looks also quite impressive, although I am missing some more deeper insight...

I had Ed Long show me around the flight deck at Farnborough this year. It really does seem to be an exceptionally intuitive user-friendly bit of kit.

You're right, it was not mentioned explicitly. But in my opinion, the caption "NU" and "ND" of the double switches tells the story.

They are definately trim switches!

pilots out
 
Watching this video i could not help feeling that
This technology advances are dumbing down more and more our profession
thus pushing us pilots little by little out of the cockpit !!!

The B777 inspite of its big yoke is fly by wire and has trim switches. They are only used for speed changes.

This has a pretty good explanation of the cockpit. Can anyone tell me what is "trim to speed"?
