requested AIM-120 Missing Contrails

Oh please.  You know all of that is BS, this is all about said targets knowing when they're being launched on in TWS.

All for the sake of realism (and fairplay).

 

Besides there will still be cloudy days, and they can still fire u ndetected below 8km(well due to  loft a bit lower).

 

Visualy it will be exciting to see a novice pilot trying to inrease PK, drawing trails in the sky up there.

Hi @Flappie,
no one from ED really commented on this.

Is a track file required or is this not considered a valid request all together?

P.S. I called the thread "AIM-120", but I guess most if not all A2A missiles are missing this effect.

Short reliable tracks are always welcome because they make testers save some precious time (to check or document more bugs, or to test fixes for instance) In this case, I think what we need most is real life videos of pilots testing various air-to-air missile types from a high altitude, so devs can see what it looks like (contrail size, transparency...).

If you can gather 4 or 5 good videos for different missiles, I'll make a request.

Thanks a lot for replying.

On page one of this thread there are three separate real life videos of 120 contrailing. Some of them are contrailing even before the actual launching platform starts contrailing, but since we don't have any data on altitude, it would be safe to say that as soon as the aircraft start contrailing, the missiles should too.

I can't really prove that missiles that smoke contrail also, since the trail they leave behind a smoke anyway, but I think it's safe to say thay if smokeless one leave contrails, so should the classic ones.

Only altitude info about the Slammer contrailing that is known to me, comes from 1999 Eagle-Fulcrum engagement where according to the F-15C pilot, missile launch happened around 24-27 thousand feet. Fulcrum pilot visually confirmed the contrails and hense ordered evasive maneuvers. I can leave a link to YT videos veirfying these claims, if needed.

Thanks again.

Thanks, these should do for the AIM-120 alone. I think we need some more videos showing other missile types being fired at high altitude, so all A2A missiles get contrails at the same time. Do we have something on R-3, R-27 or R-77 missiles?

It's quite difficult to find videos of high altitude Russian/Soviet missile shots. I will do some more research in the next days.
Here is one of, what I presume, is R-77-1

Another high-altitude R-77-1 shot

Here's a high-alt R-73 shot

High-alt shots from Su-27, but I am not sure what type of missiles are being fired. I guess it can be either/or R-27, R-73

 

As I have mentioned before, it's very difficult to tell with "smokey" missiles which part is their smoke and which part is the contrails, but it's a pretty safe bet to say that as soon as the "smokeless" missiles start producing contrails, so should the "smokey" ones.

I see no reason why an 120, for example, would contrail but R-27 would not - you can substitute 120 and R-27 for any air-to-air missile in this sentence really.

Seems I bumped into AIM-9 here with contrails:

You can stop looking for videos, it's just "simple" physics: https://en.wikipedia.org/wiki/Contrail
And @Flappy: You can read here: https://www.bundeswehr.de/de/organisation/luftwaffe/aktuelles/mythos-kondensstreifen-die-luftwaffe-klaert-auf-5474662
Is it enough of information now?

Now you are ready to go

[Flappie]

Yes, I was planning to request it, but there were issues far more important in the last few months. It's now requested.

[Flappie]

I ran some tests. DCS A/A missiles do produce contrails. They are thiner than aircraft contrails though.

Is the global consensus making these bigger?

R-77 no contrails.trk AIM-120 no contrails.trk

Based on the other videos and this one I would say the contrails should be more visible at altitude
