That is a work around.. but that does not fix the bug

That depends on your definition of mild..

Per the Australian Bureau of Meteorology

They only issue airport warnings for mean wind speeds of 18mps.. Which means there is nothing to worry about at wind speeds less than that.. And that is for airports with cement runways.. But we are seeing planes spin at far less wind speeds (more than half of 18mps) while sitting on grass runways.

So I think Ill side with the Australian Bureau of Meteorology definition for now, until someone comes up with a better one.

No need, in that I am able to take off in any wind setting in CoD.. Not that my skill level or anyone else changes the fact that this is a bug that needs reporting

You don't need to tie your Spitfire with ropes in CloD with winds below 18mps, or even higher. You just need to use differential brakes and propwash when taxiing.

If your plane starts to slowly spinning with winds acting, use wheel brakes. Wind act on control surfaces, and vertcial stabilizer works like a sail in crosswind. Thank's God for that and differential brakes, or we'll need ground crew in CloD to push our aircraft around...

The planes in CloD don't fly away or spins like crazy even in strong wind speeds. And we don't need a truck to spin a Spitfire using tailwheel, or taxiing will be really hard.

Use brakes. Or give some proof that the behaviour in CloD is really a bug. I don't think so. After all, the Australian Bureau of Meteorology don't said that you can sit on your Spitfire without brakes and with tailwheel unlocked with some wind and the aircraft will not spin.

We need more consistent data to confirm this is a bug. Can you provide some usefull info?

Your missing the point my friend..

I realise there is a work around for this bug..

But the fact remains that planes will sit-an-spin on a grass runway at far less than 18mps..

Your own video shows a Spit spining at 10mps and there are other videos showing planes spinning at 5mps.

Which is a bug IMHO

In either case lets provide 1C with the info on this bug to take a look at it, if they fix it fine, if not we use the work around. No big deal

Why it's a bug? One Spitfire starts spin in crosswind in wich wind speed, with brakes off and tailwheel unlocked?

I don't know. You know? Please, provide us some data.

What I can see now in CloD is that planes have decent inertia and friction with ground when taking off and landing. And in taxiing in mild wind. I really don't know how a Spitfire handle each wind speed on ground. We have some real Spitfire pilot here?

I really don't know, so I cant say it's a bug.

In my humble opinion, some WWII aircraft like a Spitfire need to runs smoothly over grass surface, or will need much more power to taxiing, maneuver and take off. I believe that the Spitfire tail was made to spin with ease on ground, isn't?

Agreed, nor can you say it is not a bug

So we will have to agree to disagree

Eitherway it does not hurt to report it and let the 1C take a look at it

One other thing that make me think it is a bug is you don't have to 'hold' the breaks to make it stop spinning..

Just 'tap and release' the breaks and the plane will stop spinning..

At least that is what I am seeing when I do a test..

And that tells me there is a bug..

In that the wind is the same before and after the tap of the breaks

Therefore once you release the breaks the plane should start spinning again

Based on your logic

But it doesn't

So, by 'tapping' the breaks you have changed someting.. or in the software sence.. initilased a variable that was not initlised prior to 'tapping' the breaks..

But again, we can agree to disagree on this.. It does no harm to report it and let 1C take a look at it

I propose in the other thread a theory: the spawn logic put the plane "flying" and the friction will not start properly without brakes on. But I really don't know if all the behavior of aircraft when taxiing with wind is wrong.

Just need to ask these guys:



I really don't know. If all is correct, just set "brakes on" as default when spawn, a simple change. If all the wind settings are wrong, specific work is needed. But we need some expert advise.

[ACE-OF-ACES]

So, in your testing, did the plane start spinning again 'after' your tapped the breaks?

Well sure if you have it set real high.. the plane will jump up into the air as was the case in your 50mps video.. breaks are no good in those cases

But I am talking about the 5mps and 10mps cases that are WAY below the Per Australian Bureau of Meteorology warning levels of 18mps

Lets assume for a moment that your right and there is no bug and that 5mps wind speeds should cause the plane to spin.. And that when you apply the breaks it stops spinning as expected.. But if your correct, than once you release the breaks it should start spinning again

Yet it doesn't!

The plane no longer spins after you tap the breaks..

As I stated before, based on my software background, this has that feel of a variable that did not get initialized correctly and got initialized 'after' you tapped the breaks.

That is why I consider this a bug, because if it wasn't a bug than the plane should start spinning again after I released the breaks

Yes, I said the same too: spawn logic don't works Ok with brakes off. But now after all this discussion I have the curiosity to know in wich wind condition a Spitfire will start to spin into wind...
