Dynamic Suspension Based on Gross Weight and Animation on Landing

[ykeyre]

The wheel buggy has dynamic suspension based on gross weight in the real aircraft. At lower GW, the aircraft should sit higher and sit lower at higher GW.  Also, please can you implement suspension animation during landing like in this video?https://www.youtube.com/watch?v=eHUe9W6zn1U&list=LL&index=7

I will definitely second this. I have never seen such terrible main wheel animation like on a350 on such a high quality addon. I will also add following:

- nosewheel animation when braking is also totally unrealistic, with the nosewheel itself bouncing when braking, and suspension almost not working at all

[ykeyre]

Here is another example but with an A350-900.

Here's another example of the main landing gear and suspension during take-off rotation. Please, can you pass this onto the developers?

Agreed, gear dynamics is really basic now. Suspension, dynamics on touchdown/liftoff, the rebound from a touchdown with higher than normal rate of descent. They all need some work.

[darialove]

I agree. I think they should improve the landing gear animation because, currently, the landing gear clips into the ground upon touchdown. i think it's all about contact point.

[the_taurus01]

agreed.

This photo shows the state of the landing gear from the same perspective when the aircraft is at its lightest and heaviest weights. The suspension is moving properly, but the tires are also sinking and floating unnaturally. This issue needs to be corrected first.

Additionally, the suspension's range of motion seems too narrow. It should compress more under maximum weight. Increasing the suspension's range of motion would make it appear more realistically compressed during landing. The current suspension of the iniBuilds A350 simply lacks sufficient compression.

Also in their current stream they completely omitted the topic of suspension. There is apparently the correction on the sunken main gear on landing but I think they think the suspension is completely correct.

The suspension is clearly not modelled properly!

 

I don't know why it's so difficult to understand, since all modern airliners have it. The A350 is supposed to be the "ultimate airliner" experience, hence modelling dynamic suspension is a basic expectation! As you can see in the video above, the suspension for the gear buggy is fully extended and only reduces in height based on g-force influenced by gross weight and rate/angle of descent.

Alright. So we ascertained it’s wrongly animated and also wrongly modelled, which most likely goes hand in hand with the flight model, aircraft model and ground physics.

 

Inibuilds: what are you going to do about this?

我们已经在1.0.5中看到了起落架着陆动画的一些改进，但仍然不够，希望他们在即将到来的更新中继续调整它。

Sorry，I mean we've seen some improvements to the landing gear landing animation in 1.0.5, hopefully they will continue to tweak it in the upcoming updates.

Addtionally，I recently updated to 1.0.6，and i noticed the bogie sinking into ground issue came back(which was fixed in 1.0.5) .😂

Thank you. Will inform the team.

Hi there,  

In version 1.0.7, the landing gear sinks into the ground upon touchdown again.😂（which is fixed in 1.0.5）  

- A350-1000: The left landing gear is affected.  
- A350-900: Both landing gears exhibit this issue.  

Could this be addressed in the next update? Thanks!

It has been noted. Thanks

As you are probably already aware, the tire floating bug still remains. (v1.0.8)

This photo shows the -900 and -1000 gears from the same perspective.
The photo was taken with the lightest and heaviest conditions.

I have investigated the cause of the change in tire position depending on the weight, and it seems that the calculation of “static compression” and “max compression ratio” in flight_model.cfg - [CONTACT POINTS] is often not correct.

I am not an expert, so I would like to ask another manufacturer's expert to improve this problem as soon as possible.

 

（As for the 1000, the tires are not floating, but their position has changed due to weight.）

1.0.8 and still no changes on wheel animation? I can’t read absolutely anything in the changelog.

I simply cannot grasp why.

This has been stated before, sometimes 'easy' fixes are by no means easy and take time, the team is aware of issue and will be working on fixes but sometimes it takes time. Thank you for your patience and I hope your enjoying the A350 in the mean time. 👍

[kosta]

Ok, thanks for the info.

Actually not, because it’s a complete turnoff having it perform visually and physically incorrect and the feeling on the takeoff and landing is very unsatisfying, that me personally, I parked it until you fix that. 
 

I really don’t know how it’s with others, but most likely the most joy is coming from the ops on the ground and short after takeoff and short before landing. Rest is cruise where one can more observe than anything else.

I am happy with this masterpiece also accepting a few bugs. Just wait and will be perfect for you, trust me.

The "problem" is that one of yours wrote in the discord channel that it was a bug unintentionally slipped into the release version because it was not like this in internal testing. That is why the "easy" comes from. Obviously, this was not the whole truth then, cant be that complicated to get something working again when it was already working prior release. But hey, in the end it is just the landing gear, no? 😉
