Toe brakes too sensitive at low taxi speeds

[N55E008]

Moin.

I find the toe brakes to be too sensitive when taxiing at low speeds ( 10kts or less ):

when applying manual braking during roll out, everythings fine until slowing down to below 10kts, then suddenly the brakes become much more effective without changing the deflection of the toe brakes, leading to full braking action as if max manual braking were applied.

Best regards,

Thorsten

I also find this too. After around 1.5-2.5 seconds of using continues' of *light to medium* braking action, the brakes heavily come on. Must be fixed ASAP!

Thankyou.

Hi and I disagree. It works fine for me. Check your X-Plane datarefs (data output) to see how much brake input you have.

Hi Jan,

have the same oversensibility below 10kts with my really good  MGF Crosswind pedals  ,they are absolutly linear and sensitive

Did get my MFG Crosswind pedals yesterday. The first I noticed was the toe brake sensetivity. Braking at low speeds is like hitting a wall  very hard or impossible to brake smooth. Will do some more testing today with monitoring dataref for braking etc.

On my video you can easily see that below 10kts the aircraft is braking very hard. You can see the dataref for the brakes on the top left corner.

Did you guys check if your parking brake was still set, maybe?

I ran some test and have the brakes at 0.1 (approximately) - my deceleration is much slower and steady all the way to 0 kts (no sudden increase in decel below 10 kts).

Can confirm that parking brake was not set or used.

[Tom Stian]

I have the same issue with a other aircraft. So its either a X-Plane issue or a plugin that are messing it up. Will try without any plugins tomorrow.

Cheers.

Did test without any plugins now. But the result was the same. Below 10kts the brakes get super efficient. even with only 0.1 brakes.

So I wonder what you have done too your x-plane to have smooth braking below 10kts

 

[Litjan]

I have done - nothing .

I wonder if there is something else coming into effect for you here - some cross-assignment of braking, for example. There are keys that can be set up for braking, namely V and B, and I think you can also adjust if they "toggle" or "push to brake". Some users reported that the "B" key also toggles the Beacon for them - I think it is easy to map a key to braking by accident, and have it set to "always brake" after toggling it. Maybe you push a button to do something else (get a certain view, etc.) and it also "toggles on" the brakes?

Another idea: Try the same on a "default" airport (not a custom one) - maybe the designer did something that affects the ground friction?

There is also a certain code in place (default X-Plane, not IXEG) that adds "really strong braking" at very slow speeds, this is to avoid computational creep and flutter which used to make airplanes "shimmy" and weathervane in crosswinds - but this should not kick in at 10kts.

Thanks for your tips. 

I dont use keyboard bindings. Have deleted most of them. 

Also tried on a default airport, but same behaviour. With IXEG and a default X-Plane aircraft.

With P3D the braking is smooth as butter, so I really want to find out why this is happening to X-plane.

I could understand if everyone had  this issue, but when you dont have it should be possible to find a solution to it.

I have the same issue, Tom. But sadly I also don´t know what might cause it.

[Tom Stian]

With XP 10.50 the braking are fixed i think. My results from my first testing is that the braking is smooth now below 10kts. Nice

[Litjan]

Thanks for letting us know, Tom - I wonder what fix affected that one...
