RWR Launch Warnings

[0xDEADBEEF]

I just downloaded the newest update and was super eager to try it finally! :joystick:

 

There used to be a launch-warning for the Aim120C that had some funky cirping sound. This time I only got the lock warning and was like, oh, I'm hit! oh, he launched?

 

Is this the way its supposed to be working or are you reimplementing the launchwarning? Only getting the lock tone from an F15 and no launch warnign will make it quite difficult fighting them I'm afraid ... :huh:

 

Oh and right after I was shot the game crashed with this dumped to the log.

Forget what I just said, this time I got the chirping sound from an aim 120B :huh:

no idea why i didnt get it before ...

[Rlaxoxo]

Still WIP

[SDsc0rch]

when/if you are banked such that you've moved the RWR antennas/sensor FOV away from the missile, you won't get an indication

 

or, similarly, if the missile is approaching you from outside the antenna coverage area, you won't get an indication

 

in the eagle, the antennas cover +/- 45-deg above and below the horizon - in the flanker i believe it is 30-deg

 

does anybody know what the angular limits for the mirage RWR antennas?

[0xDEADBEEF]

I have tried a couple of times now. I can confirm that the 120C launch warning is not reliable. Sometimes it comes (the chirping), sometimes there is only the lock warning without the launch. Also, sometimes the lock warning would remain if the bandit is splashed (F15). These findings are head on against AI with 0° bank angle.

 

It would be very practical if the RWR would be fixed next, this seems to be the last remaining thing that keep the mirage from being useful in multiplayer. If you get Spamrams launched at you without getting a notification, this is a big disadvantage.

 

While not on topic, it also seems the radar elevation in STT does not do it's job as designed, i would most of the time loose lock even though I notch less than 30 degrees.

[PiedDroit]

Something's not clear to me, are we supposed to get a warning from an AIM-120?

I thought it was guided by datalink begore going pitbull.

Which means you won't get a launch warning. Lock warning at best.

Slammers have their own radar and once they're close enough they start using it so target will get get spiked but not sure about the RWR launch warning

[AussieGhost789]

Hang on, are you guys actually getting launch warnings? The only audio warnings I'm hearing are the lock warning and new emitter warning. Of course you can use that information to infer that there is a missile coming at you when it's an ARH missile because an M will pop up on the RWR. But it's of little help when facing a SARH equipped opponent.

 

I was under the impression that the actual launch warning is yet to be implemented.

Yes, that's what "pitbull" is - going active with on-board radar.

My understanding is that launch warnings against SARH were possible when the radar would change it's emitting pattern from STT lock to weapon guidance, the RWR would pick up the difference.

 

To sum it up, here's what I understood from various discussions:

 

• SARH:
  
  • Lock warning when locked in STT
    
  • Launch warning when switching to weapon guidance.
    

   

  [*]ARH (with datalink):

  • Lock warning when locked in STT
    
  • Maybe Lock warning when locked in TWS (probably not)
    
  • NO launch warning,
    
  • Missile alert when the missile goes pitbull­

That's my understanding too. TWS locks give no notification to the locked aircraft.

 

Edit: you *may* get a launch warning for an AMRAAM in aircraft that can detect the IR bloom of the missile, but I think that's only for the A-10C, not sure.

[SDsc0rch]

TWS gives a "nail"

 

STT/A120 gives a "spike"

[PiedDroit]

That's my understanding too. TWS locks give no notification to the locked aircraft.

I don't think the IR detection works at such distance, otherwise all fighters would have it already, in practice it seems only fitted on A-G specialized A/C. The one (D²M) that exists for the Mirage-2000 is used on the D version which is the ground attack variant.

 

TWS gives a "nail"

STT/A120 gives a "spike"

How does that translate on the RWR? Sorry not familiar with all terms (nail?).

Thanks!

the nail is an intermittent lower-freq "beep" that lets you know someone is scanning ----- mostly this is what you hear

 

a spike is a higher-pitch faster rate alert that catches your attention to tell you you're being hard-locked or a missile is inbound ---- this is important and you need to take action

 

you report "15 nails, nose" or "29 spike, right two-o'clock"

As it works in DCS; if locked in STT you will receive a lock warning and when launched on you will hear a launch warning, be it ARH or SARH. In the case of the F-15 firing in TWS, you wont get a launch warning until the AMRAAM goes active, and you will receive no lock warning (until the missile goes active).

 

My question was focused on the Mirage 2000 in particular, as people are talking about getting launch warnings yet I am not. Just trying to figure out if there's something I haven't turned on, or if people are mistaking the new emitter "ding" combined with an M popping up on RWR as the launch warning. Of course, that does indicate an incoming missile but it isn't the actual launch warning. The only reason we can interpret that as an incoming missile is because we see the M on the RWR. And my point was that doesn't really help when facing SARH equipped opponents because no M will appear on the RWR as there is no detectable emitter on the missile itself.

 

Edit: Is the RWR on the Mirage 2000C actually capable of detecting missile launches?

 

Edit 2: Ok, now I've heard the launch warning and it has left me confused. I'm starting to understand the questions that began this topic. I am hearing the chirp that was described, but only sometimes, and it seems only for AIM-120's. This is weird.

Ok, that was a DCS-specific question, nevermind then - I didn't fly with the new RWR yet. I will wait for the next stable release then I might be able to comment ;)

Regarding systems, there is only one switch for the RWR, so it should be quite straightforward. No funky configuration that I know of.
