Asymmetrical braking

[grim_reaper68]

Hello

I noticed that the mirage F1 has an asymmetrical braking issue. When i'm braking after landing, the plane always go to the right. Even if i use the pedals or if i push the brake button assigned on my hotas, so i'm sure it doesn't come from my pedals. I've tested other planes (M2000, F14) where i have no problem.

Yes, this is a good point. I always thought it was due to how hot she lands and the narrow undercarriage. Deploying the chute helps me some but it’s still never perfect. Maybe it’s just a I need more practice on my part, but I do agree she is tough to keep lined up on landing. I’ll play with it some today to see if there is something I’m missing. I have toe brakes, so I should be able to null that out.

As said, i've tested with pedals and keyboard with wheel brakes (both activated at the same time) and i had the same reaction.

Just to make sure, is the anti skid turned on?

[grim_reaper68]

Yep

I also find staying straight under braking almost impossible, especially if the slightest amount of differential braking is used. I more often than not just slam on full brakes to avoid this but even then the nose wants to wander.. Doesn't seem right

I can confirm that this still occurs in 2.8.5.40170 MT.

Same problem with me. It's very difficult to brake straight, the F1 goes to the right.

Same here. I did a little training with just runway runs to try to get better, it's really hard to brake correctly and you get really fast in what we can call ''pilot induced oscillations''.

Is there any word from the devs about that ?

Hi, we're going to look into it. Development of the BE is now at full speed so we will focus more on bugs again afterwards. Out of curiosity, do you experience any difference between CE and EE?

[grim_reaper68]

Nope, it's the same for both version.

Thank you for sharing your concern about the braking issue with the Mirage F1. To address this, I recommend ensuring that your controls are calibrated correctly and also checking for any known issues or solutions that have been shared by the community or developers. By doing so, you can optimize your flying experience and ensure safer operations.

I have a single axis for both brakes, so both left and right are supposed to brake exactly the same in theorie. Yet, even with gentle braking, the aircraft wont hold centerline.

[grim_reaper68]

As said above, tested with pedals and keybinding, so with a key, both brakes are used with the same force. I overviewed the brake pedal pressure on the axis window, and in both case the pressure on the left and right brake were at the same level. I tested with gentle pressure on the pedals, same force shown at the axis.

Just a precision, I just made a  new test, F1 aligned on the runway, 20% fuel no loads or ammo, full flaps, full brakes, full AB, at 700°C, brake release, waiting for speed being at 150 kts, then idle and full brakes for the first test, another one with 50% brakes then full brakes, and another with keyboard pressing, 2 runs for each. As result, the F1 CE goes to the right every time but the F1 EE goes to the left, so each version goes on it's own side. Maybe there is a difference in the programming of each version, so the solution must be in the middle .

Hope it helps you to find out what causing it.

 

and the track, it's a single run of each . Calm weather condition of course.

I flown the F1 today and I found that turning completely off the steering system will help you keep centerline on braking. It doesn't overcome the problem since with the EE, as grim_reaper68 tested, the aircraft will go on the left on braking, but having only the rudder available reduces the induced oscillations when braking, making it easier. I should try with the SPAD and steering both turned off.

Hope it will help by the time devs take a look at this.

Hi guys,

We've corrected the problem that made the aircraft have a tendency to go left when braking on take-off (there was an initialization issue in the rudder trim, and it was left the majority of the time but it also went to the right at times). The braking instability still remains, we are investigating what adjustments might be needed. Keep in mind work with the BE might take priority, so bugs/problems/features might take a bit longer than usual to be resolved.

Any update on this? As it's still on the plane and It's really hard to land properly the plane :c
