CTL COLUMN NULL ZONE and CTL WHEEL NULL ZONE?

How to setup these options realistically? How much input real aircraft requires before "the FBW pitch mode changes to manual control from the hands-off speed stability or path hold modes"?

Unless you're in a real 777, there's no "realistic" setting.  You have to play around with it to make it work with your specific hardware.  That's why it was added: different hardware behaves differently/

Understand that, that's why I asked. I want to change numbers (if necessary) to set my hardware works as close as possible to real 777.

 

To rephrase: What is required in real 777 for the FBW pitch mode to change to manual control from the hands-off speed stability or path hold modes? Specific amount of force applied to column? Specific amount of movement applied to column? Something else?

Here's what I did:

 

Check out the video posted here: http://forum.avsim.net/topic/447190-how-to-hand-fly-with-cu-law-aircraft/ Base on the video, observe how much deflection he gives to the yoke and the plane's corresponding response. Then I adjust my control's null zones until my deflections approximately equals his deflections. Here's another hint, your yoke's deflection should also approximately equals the virtual yoke's deflection in the VC!

 

Then you can check your settings and see if you can fly like in the video. Your yoke's deflections should nearly match his for the shown airplane response.

 

I did this through FSX's controls, however. I left the FMC null zones at default.

 

Anyway, you'll just have to do the work. There's nearly infinitely many combinations of hardware, software, and user's judgements, so unfortunately no one can just say "use null zone 5%".

I found it didn't make any difference, even setting it to 10%. I get the same control reaction regardless.

 

Best regards,

Robin.
