ALR-67(v) Update

[Zeus67]

The ALR-67(v) RWR is being updated.

Here are the following changes:

1. The Azimuth Display (AD) has changed.

2. Emitters are now being discriminated into three categories: Non-Critical (SAFE), Critical (Threats) and Lethal (Attacking Threats).

3. How the emitters are displayed in the AD depends on their category.

4. Two filters are being implemented: Normal and Priority contacts. Limited Display.

Normal (N) = All detected emitters (up to 16) will be shown on the AD.

Priority (P) = Only Critical and Lethal threats will be shown.

Limited = When selected only the first 6 Non-Critical emitters will be shown.

5. HUD will show only Critical and Lethal threats to prevent cluttering.

6. AD center will display RWR status.

7. Sounds will be improved.

 

 

Based on al531246, the bands have been edited:

Inner: Critical.

Middle: Lethal.

Outer: Non-Critical.

Hello Zeus67,

does it also mean that the sounds are now working?

Yes. It also means that the sounds bug will be squashed.

Glad to hear that. Looking forward to this update!

[Kula66]

Great news Zeus, thanks for the update.

Great work. Thanks for the news.

Brilliant!

Good news, thank you for listening to our posts.

 

So this is just awaiting ED push to patch? Or still quite some time left until its released Zeus?

RAZBAM, the RWR threat ring labeling and position is incorrect. You have 3 bands;

 

Nonlethal Band - search radars and other radars not capable of launching missiles

Lethal Band - radars within active tracking range, not necessarily locked onto you though

Critical Band - radar is within engagement range, can also be here if the radar has launched on you

 

From inside to outside it should run; Critical, Lethal, Nonlethal.

 

As for HUD RWR I'm not sure exactly how the stem's should appear. I have a couple videos but I don't know if they're nonlethal, lethal or critical threats.

New RWR format test.

It is more useful to determine threat priority and position.

Interesting. The only transposed position are the critical and non-critical bands. The middle ring still is the lethal band.

 

Unfortunately although both the Hornet and the AV-8B use the same device, both use different versions. The AV-8B uses the ALR-67(v), which is the oldest one. The F/A-18 uses the ALR-67(v2) and now the ALR-67(v3).

 

 

So my docs could refer to a different version than yours. Still thanks for sharing this.

Any options to disable the HUD Symbols like in the Hornet?

None that I've seen.

For landing, I just turn off the EW. Part of cockpit cleanup and before landing checklist. In the absence of a declutter switch that's about it. Though the new modes noted are promising for less mess on the HUD.

I'm convinced there is a button that enables / disables HUD RWR but I cannot find it. I've got a lot of AV-8B documentation but so far as I've read none of them mention an option to toggle it.

Probably the button is in the EHSD EW page.

Just checked todays 2.5.3 update for the Openbeta, was there a chance this RWR fix was going to come today? guess it needs further tuning?

RWR is still being upgraded. It will be available in the near future.

Yes?! So the last posts' stuff maybe made it into the update? Just a guess...

[jonsky7]

So not in today's (29th-Aug-18) DCS patch right? As mine is the same as before??

After many hours of research I think I've worked out the HUD RWR system for the AV-8B. To begin with I can say RAZBAM's simulation is 95% correct. There are 5 key points I will note below, if anyone has contesting evidence please let me know.

 

1) The HUD RWR cannot be turned off, see the RWR rotary on the right hand side of this image. With the rotary off the ECM page will not function.

 

2) HUD RWR is limited to 6 threats at once

I cannot find any documentation, imagery or video showing more than 6 threats on the HUD at any one time. All documentation shows a maximum of 6. Also EWM (Electronic Warfare Menu) page which works very similarly to HUD threat display only displays 6 threats. (see page 23-48 in the NATOPS)

 

3) The three HUD RWR symbols are as follows;

Non-lethal

Lethal

Critical

 

4) Unknown and friendly emitters always appear as Non-lethal threats. I think this is achieved by the RWR analyzing the emissions for IFF codes before going onto the HUD?

 

5) I think non-lethal threats only appear for 5 seconds on the HUD after detection. I'm not certain about this though.

Only correction, the AV-8B cannot discriminate between friend and foe. The ALR-67 is not connected to the IFF. So in your sample it is classified as Non-Lethal because it is a search radar.
