elevons moving during taxi

[bkthunder]

For the sake of realism and authenticity, please let the FBW move the elevons up and down also during taxi (when you hit the brakes, small bumps etc.).

 

This is a feature of all FBW aircraft and is visible already in DCS Su-27, F-15 (yes I know, this one is not FBW), and in BMS F-16.

 

I remember at one point also the M2000 had this effect, then it was removed.

 

If you have a look at videos on youtube you can spot the small movements, for example in this video

 

 

Thanks

[razo+r]

can you provide a timespamp please? I wasn't able to spot anything you said...

 

Also, keep in mind, that the -5 might got a FBW upgrade.

I think there is a bit of movement visible at 1:49 on the right trailing edge

but could also just be an illusion and the effects of the heat in the air.

 

Also not sure if this is what bkthunder requests or the pilot touching the stick.

It seems to be a rare thing, compare to the F-16 which is very visible an common.

That's exactly what I meant, thanks, I struggled to find a video where it was so clear :thumbup:

 

Anyway, I remember it was implemented at some point. To me it seems like you are "stopping" control laws below a certain speed. What if you let the FBW on all the time? That would give such effect I think.

 

P.S. Agree that on the F-16 is particularly evident, but on the Mirage is definitely there too, just the elevons are smaller, so you see it less.

[bkthunder]

You are absolutely right, it was there before, however at some point I reduced the stabilization gain to such a degree that it was very small to none at taxing speeds. I more or less went back to the original way and doing heavy breaking the effect is pretty much as seen in the video now :)

 

Haha! cool :holiday::punk:

What if you let the FBW on all the time?

The flight computer or the FBW system is always on with electrical power. So if the generators and the battery are working, so is the FLCS/FLCC.

He was referencing a possible speed limit the devs imposed on the FBW.

Got that, and I was saying the FLCS should always be on. So, what are you saying?

F-15 (yes I know, this one is not FBW)

 

Er, the F-15C is most certainly using a variant of FBW called Control Augmentation System.

Its not a variant... its just an analouge dampning crontrol device

F-15 is not using FBW system by any stretch of imagination

[Vladinsky]

The F-15 CAS and hydromechanical systems work together to provide more or less the same thing a FBW system would, so while yes, calling it FBW is wrong, to say that it has nothing to do with FBW and is a simple damper system is equally wrong.

 

The inputs through the stick force sensors are sent directly to the rudder and stabilator actuators after passing through the Pitch and Roll/Yaw computers. Even if every single mechanical linkage breaks or the stick is welded rigid the plane will be controllable, with degraded performance obviously.
