fixed "LOST" indication on HUD after shooting in TWS

[NoJoe]

I'm not sure if this is a bug, or just me doing it wrong.. But I keep getting the "LOST" indication flashing on my HUD shortly after shooting an AMRAAM and cranking. DCS version 2.5.6, and I've already run a repair after updating just in case.

 

I've made a simple 1v1 mission in the Nevada map of me vs a single MiG-29. In the attached track I fly right at him with him bugged in TWS. I fire when in range, then as soon as I crank to the side (keeping him within the radar gimbal limits) The time-to-active indication gets replaced with a flashing "LOST" indication. Why is this?

 

From what I can tell, that indication means that the L&S track file has been, well, lost? I'm struggling to figure out why that's happening in this situation. The L&S symbology remains visible on the radar DDI, and the HUD target box stays there too. In other words it doesn't seem like I've lost the L&S trackfile.

 

Thanks in advance for taking a look at this!

 

[EDIT] What in the smurf... Now that I watch the track reply, it's not showing "LOST" anymore. It shows the steady countdown to ACT, then TTG as expected. And it shows my first missile hitting (when I recorded this, my first missed and I went in for a second shot). I'm very confused.

[EDIT2] Since the track seems to play out differently every time I watch it, I'm also attaching the mission file. Steps to reproduce:

 

1. Launch mission.

2. Switch radar to TWS using OSB

3. Switch TWS to Auto with OSB

4. Increase radar display range to 40 miles with OSB

5. Select AIM-120C

6. Fly straight at the MiG

7. Once in range, fire and crank to the side about 45 degrees

 

Actual result:

"LOST" indication pops up once the target is about 20 degrees to the side. Target remains bugged and visible on radar screen this whole time.

 

Expected (?) result:

"ACT" countdown remains visible while the L&S track is present.

[CHECKING] AMRAAM lost instantly

 

On this track + tacview you will see theses AMRAAMs instantly lost after launch in TWS or RWS.

+ Getting the "LOST" indication on the HUD regularly with the AIM120C after 2.5.6, in TWS or RWS. Only when within 8-9 miles does it seem to display the TTA / TTG appropriately.

I confirm this!

 

In TWS, a Boxed target in the HUD disappears the moment an AIM 120C missile is launched.

same here, in TWS i get "LOST " indication on HUD . 2.5.6 update in tws with AIM 120 C and AIM120 B

It almost looks to me that the "LOST" indication pops up any time the DLZ max range decreases below the bandit's current range.

 

For example, while engaging a two-ship flight that is in trail (so one plane is a couple miles behind the other). I fire on the lead plane when it is in range. So far so good. But as soon as I press the pinky button to swap to the trail plane (which is outside the max range cue) I get the "LOST" indication.

 

Not sure if that's right. It "seems" like the "LOST" cue should only pop up if the max range changes for the current missile in flight (as a result of the bandit's maneuvering; my maneuvering cannot have an effect on my missile once it's already in the air). But then again I don't have any source for the correct behavior, so I don't know for sure. Something for the devs to check?

Reported, thanks all!

Awesome, thanks NineLine!

LOST cue?

 

I'm curious what exactly prompts a LOST cue on the Hornet radar? I've seen it a few times on dropped tracks and contacts where it makes sense, but I've also had it happen while guiding an AMRAAM in STT where I had a solid lock the whole time and was still several seconds TTG. So if I've got a solid STT lock and a missile in flight and get a LOST cue on the HUD and radar, what does that mean? What got lost?

Interesting, so I guess it's a bug?

 

Of note, I'm seeing it in STT as well, and I'm also running stable so I'm not on 2.5.6 yet.

So, has this been fixed or what cause I got this the other day when firing AMRAAMs and was like WTF, cause I was still dead head on at the target in an STT lock at around 20 miles. Missile seems to have completely lost track right off the rail. Seems to happen every time.

This is fixed, if you are still having problems make a new thread with short track replay examples. 

thanks
