COOP partially implemented

In such a case you can enable IRST search mode. Put your nose on the target. And the target dot will be right in the middle. 
 

Often you can put the TDC in the middle, hold the lock button. And just put your nose on target to get lock since your TDC in IRST search covers 4x6 degrees 

Then you can get radar ranging up to atleast 35 km 

Yes and using this mode with Coop you can have the radar lock on outside 10km, and employ radar guided missiles, by pressing the lockon button a second time.

@CrazyGman Thank you, TIL.

Worth noting is that you have to be in radar DUMMY mode, otherwise I couldn't get it to work

There are other options for the above scenario. You could lock this far away but visible target with helmet and change mode to IRST search for radar ranging, or do the same with OPT or IRST vertical scan. OPT is most precise

Correct...at this point we've mentioned in this topic that you need to have the radar in dummy mode to work in tandem with the IRST so much I didn't feel the need to mention it again. But for clarity yes

On your table for ISRT CC you have if stated that if outside laser range STT lock immediately no matter if inside or outside laser range.

However currently in game with radar in  dummy and coop enabled The radar only locks on to the IRST track and allows you to guide radar missiles when inside 10km. Outside 10km the radar doesn't lock, no diamond or radar ranging appears and R27R will not be primed to fire.

 

Same for if locking with helm/optical. You will lock with IRST, but radar in coop.amd dummy will not lock on untill inside 10km.

Currently with IRST search If you lock on with IRST at any range with radar in dummy and coop enabled and you press lockon again the radar will lock on regardless of range. 

So your table implies that using IRST CC or opt/helm, The radar will lock on regardless of range.

I've tested it a bunch. In both IRST CX and Helm modes radar locks on to the irst track and preps R-27 ranging/vector at 10km (also doesn't need lockon to be pushed in this instance, will just happen automatically.)

I assumed this was normal because when using IRST CC or helm/opt that the radar even in dummy goes into what is similar to it's vertical CC mode which is limited to 10km range.

Okay updating table since we’re talking about DUMMY. To compare notes, for your testing, when the radar entered STT only within 10 km for IR vertical scan/OPT/Helm, did you do this with a second press of the lock button after acquisition Like in IRST search, or did this happen at 10 km without pressing lock a second time? 
 

Been away from my computer for a bit and have a lot of testing to do. But it would be interesting if it was like “Radar enters STT either once laser returns range or when pressing lock a second time within 10 km.”

Just tested again to make sure and there are some changes. For all examples below radar is in dummy mode and coop on:

Using IRST search. Once lock is made at any range and you press the lockon button a second time the radar will lock on target, and radar missiles will be primed to fire.

Using IRST close combat vertical. Once irst lock is achieved, the additional radar lock will only happen if your inside 10km and you press or are currently holding the lockon button a second time....or it will happen automatically without pressing the lockon button if inside laser range finding range (6km ish). As soon as radar lock is achieved R-27R's are primed to fire

Using helm or opt mode. Once IRST lock is achieved, radar will automatically lock on when inside 10km from target, and the R-27Rs will be primed to fire.

Thank you that’s very helpful

My testing confirms. However, I am struggling to find places where TP is leading, loses lock, and radar picks it up. Within laser range or after pressing lock, it shows radar leading (yet I have seen IRST leading with radar STT diamond). Yet I swear I have seen it before! Perhaps when I had coop on but radar still in ILLUM in IRST lock. Just more testing needed to narrow it down now that the rest is taken care of. 
 

I realize with radar ranging this shouldn’t happen, but only STT. 
 

One thing your results inspired me to look at. In vertical scan beyond laser range in coop, the radar was in ranging mode just not showing range. Then when laser or lock button pressed of course STT as you found out. 
 

When locking Helm/OPT above 10 km, radar was constantly on as if trying to regain lock, and thus we get to how it knows when to suddenly capture at 10 km. This seems to jive with statements that in helm/opt coop both sensors attempt to lock until they do. Yet descriptions of IRST vertical scan are much more vague.
