Contrail direction influenced by wind, is not okay !

[P3CFE]

I had this gripe a long time ago, and i thought it was solved but it sadly  is not !

Situation:
-Flight F16, 24000Ft, 300kts, Heading 360, with Cond trail , wind was 30kts/090.  and NO Sideslip !!
-External  view, looking from the nose to the tail, exactly alligned with the longitudinal direction of the Airplane.

Observation Contrail Direction:
-The contrail is NOT in a straight line into the longitudinal axis of the airplane as it should, but it is in an angle as if the Aircraft is in a sideslip
It seems that the contrail is not traveling sideways with the Aircraft in the volume of air after leaving the tailpipe.

In short: flying wings-level, with no sideslip, the contrail is angeling sideways when it should be straight allong the longitudinal axis of the Aircaft.

Hope it will be Fixed because it is strange to see smoke or contrails leaving the aircraft in an angle.
because of this, It looks like Aircrafts in DCS are in a constant sideslip while they are not.

Regards.

Wow, if it is true that airframes experiance sideslip effects, when there is no sideslip, there is a big problem with the calculations for flight simulation in DCS.

I was hoping that it are just the grafics of smoke en contrails that are faulty.

I hope that the Dev' wil react on this!?

Using these lots of exclamation marks in the opening post and underlining of statements makes a possibly valid bug report seem like an unnecessary attempt to make the issue appear as the huge scandal that will shake up the entire DCS community. It won't.

I believe this has already been reported. You might want to leave a comment there, too.

Just my way of trying to be extra clear about what i mean this time.
I was amazed that this bug is still present after i posted, and discussed this more then 10 years ago !

It should be high on the list of correct basic flight simulation in my opinion. It isn't.
It is not realistically simulated at the moment !

You are speaking for the entire DCS Community it seems, but I am just trying to help this (Almost) Perfect Flightsim become better by delivering my personal Input.

Then again, my text was a bit to loud, I agree (did adjust it).

Regards.

# Ironhand:

Thanks, I will look in to that post too

Okay "Ironhand", thanks for the link to "contrails not moving" from 777coletrain.

That link gives a far more clear and correct discription of the bug.

The discripion of the bug in that link is mentioned to the team, by "bignewy".

Hope it can be fixed in the close future.

Regards

I don't think the devs are not aware or indifferent of this effect.
However, simulating contrails effected by wind can quickly amount to a huge number of calculations, depending on the amount of aircraft, weather and flight path.
It would probably slow down the simulation a lot when it is already struggeling.
Think of an high altitude furball.

My guess, it is a deliberate sacrifice for performance.

No, it's not calculation heavy. Not more than any smoke already affected by wind.

[Hiob]

I'm not sure that is the same. Normal smoke effects are straight, have a fixed length and then vary in direction by wind speed and heading. Whereas contrails are drawn at will in any shape.
I'm not arguing. I have no idea how resource heavy something like this would be.
That was just my guess. Obviously I'd love DCS to be as close to reality as poosible (especially everything weather related).

So, bring it on, ED!

And while smoke may be hundreds of feet, a contrail has possibility of being literal miles long so yes, that is a lot more calculations.

Contrails are not heavy on neither CPU or GPU. You can have dozens of aircraft 'contrailing' in a scene easily.

Missile smoke and others are already affected by wind, perhaps there is an easy fix from an oversight for aircraft contrails.

One of the weakest parts of this sim. Weather. Hopefully a revamp is near.

Next to ATC, yes. Those are weak spots, I’d love to see improved, too.
