investigating HARM launch in SP mode is not inhibited before firing solution is achieved

[maxTRX]

Currently we can launch HARMs in SP at any time, as long as master arm and A/G master mode are on. I don't think it should be possible until the target 'box' is visible.  The mission track is too long. I'll make a short one later on.

Another 'funny' thing:  When I launched a HARM in SP a bit too early (threat emitter tracking, just before my HARM got a solid lock), the missile made a 180 and headed for my carrier battle group, 120 nm away. This could be related to an issue described in an earlier thread in this forum and already reported.

Track attached.  2 HARMs launched in Self Protect mode. I also tested the PBLK function in this track (from A/A). This part worked fine, except... I still had the HRM OVRD boxed but that's another issue, hehe.

The first HARM launched before full lock on a threat. The missile makes 180 toward my CBG. The second missile fully locked on, hits dead on.

No launch inhibit.trk

Hi, 

You do have a boxed radar source already behind you ( the AE ) you can use cage / uncage to select the 15 and you will get better results, I will check if the highest priority target should be selected however with the team. 

thanks

Hi - Just checked your track, and it looks like HRM OVRD was unboxed, so that part looks ok. 

The first missile goes for the ships as the AE is boxed in SP mode - as at the point of the first shot, it is regarded as the priority target. (HARM does not know friend/foe) Always ensure that the target you want to shoot at is boxed. I will investigate a little more however, as it may be that the priority should have been placed on the SA-15 sooner ( as it was for second shot).

Thanks.

Couple of things I noticed:

In TOO mode we have number of very useful filters we can apply, including 'HOS' (hostile).  In SP, the processing is obviously more involving. I'm definitely not an expert but I think the threat radar should at least be in pre-launch tracking mode on own ship to be included in threat ranking and allow the HARM launch.

2 pics showing Class Scan we have now in TOO:

 

 

Another thing, or a question rather:  Currently, when HRM OVRD is boxed in NAV or A/G master modes, switching to A/A unboxes HRM OVRD. Is this correct?

Actually the HARM can know friend from foe, as well as the ALR-67 (modeled in DCS too: F in front of friendly emitters in TOO, and standard HAFU symbols on the EW). That should be taken into account for the priority of the emitters. The AE ship shouldn't have even been an option...

There is no such thing as "threat radar". What do you mean by that? RWR? RWR is not a radar!

IMO it's correct. You launch A/A weapons withe a trigger, A/G with weapon releas, so in A/A mode there is no possibility of unwanted HARM release.

My question was about having override function boxed across master modes not weapon release buttons.

...and without drifting off too far from OP... Another question:  Should EW page pop up on RDDI whenever PBLK is active?

Override function is connected with weapon release - it changes behaviour of weapon release button when you're locked. So it by default is turned off when you're A/G and have to disable override manually. In A/A it doesn't matter, because you use different button.

Just in case HARM pullback involves switching you to a different page(s) on left and right DDIs, weapons release button would not be the only factor to consider.
