Impossible to maintain centerline when braking during the landing rollout

[cmbaviator]

Hello Guys.

I would like to know why the aircraft is yawing left and  right when braking with the F1. Indeed even with max manual brake, ie there is no differential braking as both brake have 100% deflection, why is the aircraft  going left and right ?

Probably the rudder-bug at work. Hopefully the next patch will get rid of this.

Yeah that rudder gets really happy on landing.

I'm glad to hear I'm not the only one!

I suspect there's something wrong going on. Almost impossible to control yaw after landing, and really easy to tip the nose once things start going wrong. I can't imagine an aircraft in service having such a demanding sweat-inducing behaviour...

Does the aircraft in question have asymmetric loading? Is there crosswind component? is there runway sloping? All these would require yaw inputs to correct. Maybe rudder pedals require a dead zone to mitigate undesired inputs when centered.

The problem as I seem to remember (it's been discussed before) is the yaw SAS channel working too hard when there's weight-on-wheels. After rollout, centre your controls and look at the yaw-trim gauge: that tells you something

Is the workaround still working with setting middle position of the yaw SAS switch before landing!?
