Nose down look

[chinjh]

I know this problem has been reported in a few closed threads before Nose up to high and on discord. But the A300 currently has this issue where it does not have the iconic nose down compression look like the A330 has.

Currently i have tried moving the weights to the nose which causes bad CG but has resulted in not much compresson to the nose gear itself. So i guess this is much tied to a modelling. issue. Also this bug is not present on the xplane release of this product.

Is there any timeline or promise or a small hint that this will be addressed in the future?  This is probably the only remaining visual gripe left with this aircraft at the moment.

On the X-plane version it is correct ! This an very important thing 

 

You can see it on the PFD

Hope it will be not closed 🙄😌

Thanks thats a really good closeup photo from a spotter. Did a small comparison yes there is something that needs to be changed on the nose gear.

This one is tough while I do see what you folks mean in some of these photos where you can say, "yeah there is definitely a nose down" but some of these photos I have uploaded like the UPS and DHL it looks as though the fuselage is flush. I am torn...

If i am not mistaken when the plane is on acceleration and deceleration at higher speeds the tendency for the nose gear to lift(floating look but wheels is still on the ground with lack of compression on the gear) is always around. The A330 is also somewhat affected by that. It is also present on the 738.
 

 

For now i am hoping the devs could at least take a look at the nose gear modeling cause there is definitely something over there that is affecting the default stance of the aircraft on the ground. I am not sure if tinkering with the flight_model.cfg's contact point would visually bluff viewers with it as i dun really know how to edit this part. Unless some other people in the forum are more willing to play around with it.

It makes me wonder if it’s a contact point thing like in the fs9/p3d days? I definitely see what you are saying.

and
\Community\inibuilds-aircraft-a300-600\SimObjects\Airplanes\inibuilds-aircraft-a306f

Both having a a file called flight_model.cfg inside there's a field called contact points i believe this is where certain parameters if adjusted correctly can effect certain parts of the plane visually. But note i do not know which points needs adjusting or even if correctly adjusting the correct points would effect. Cause currently the default nose gear itself has some modeling issue.

On the PFD you can see it realy good  hope this helps

On the ini A310 it is correct !

Tried to take a look at the data values especially for contact points from the A310 but it being an official msfs aircraft means the flight_model.cfg file is encrypted by Asobo!

[chinjh]

Some interesting stuff. Played around the flight_model.cfg namely [CONTACT_POINTS] under

point.0 = 1, 46.700022, 0, -15.574176, 2000, 0, 1.68, 65, 0.328, 2, 0.33, 22, 22, 0, 0, 0, 2

The 2 figures that has highlighted bold seems to effect the nosegear relative to the ground but unfortunately not for dampening nor compression. A high value used "1.23" and "1.25" than the bold default values results in lower nose gear which by right makes the nose down look there but this results in the nose gear sinking further into the ground. A lower level results in the nose gear gradually rising above the ground to a point it floats.

Overall there just does not seem to be any compression with whatever weights added that effects the nosegear compression no matter what contact points have been amended. The default modeling of the nosegear itself appears to be tall in default.

Another fishy area that i am suspecting is under
static_pitch =-0.2

Okay looks like i've found a little niche area without compromising too much. Also just did 2 circuits does not seem to have any CTD causing stuff. 

What to do
Locate the flight_model.cfg file at
Community\inibuilds-aircraft-a300-600\SimObjects\Airplanes
Inside this directory there are 4 variants of the A300-600 each needing some changes to their respective cfg.

• Open flight_model.cfg as notepad for each aircraft
• Ammend the line under [CONTACT POINTS] Replace the following below.
  point.0 = 1, 46.700022, 0, -15.574176, 2000, 0, 1.68, 65, 1.0, 1.15, 0.85, 22, 22, 0, 0, 0, 2
• Save what you have edited.

Note it may still look off visually but at least the nosegear does not seem to sink so far into the ground now.

[chinjh]

Looks okay now. Still not nose down enough but its a compromise.

[chinjh]

Some further checks with adjusting the nose gear contact points.

1) Abrupt deceleration causes wonky bouncing.

2)low speed around 3knots to 0 knots causes the same wonky bounce.

Currently adjusted the points to minimize the disturbances but it is still around

Seems to be the only go to while we wait for the devs to push a proper update.

Any more recent acknowledgements of this?

I won't say "this is an easy fix" because I don't know what other effects this has on things like the flight model...but if its working in the 310 I'd think a similar "fix" can be done for the 300 🙏

I did 2 long sectors and 1 very short 1 so far no issues apart from the annoying very minor bouncing compression on the nose gear when decelerating from 3knots to 0 knots with brake pedal applied.

I am getting a bit frustrated cause this was logged for 3 months without any patch issued to address it and i ended up having to eyeball a self DIY fix on the contact points.

+1 !!!

Nice Video and view.

bump

[jstnj]

@richboy2307 any chance this can get triaged? Seems like an easy win and a minor change to the visual model. 

[chinjh]

With SU15 out, is there any updates on the way and is this also being pushed for that build?

[jstnj]

not a lot of movement / official acknowledgment from iniBuilds in the A300 forum in a few weeks 😞

[richboy2307]

Thanks, as reported previously, it is logged for the team to look at.

The currently released A300 build was already made with SU15 in mind and tested with SU15beta as such. However things can change sometimes with public release of SU. so we will be giving it another look.

Not specifically about this issue, but updates in general are planned and will be coming. Cannot provide any firm time estimates on them. The team has been awfully busy behind the scenes but is working to get caught up on all the issues and updates for products accordingly.

Appreciate your patience and understanding.
Thanks!
