[CHK] WMD-7: stabilization lost when target passes the plane's 3-9 line.

[tekwoj]

In other words the moment the pod has to look even slightly behind the image starts to shake.

How to reproduce:

1. Lock area or point

2. Approach as if attacking

3. Turn away to avoid passing directly above the target

 

It should be visible in at least one target in the attached track. Problem is from what I see each time I watch this track it shows me looking in different spots and some targets get destroyed others don't.

It uses the radar to stabilize, so if you point your radar away from the locked point, it will destabilize.

Is (should) this also the case when you are within Range for Laser Ranging?

This makes it semi-useless to use for laser guided bombs as you'll almost always have the target behind you in the final phase, risking the bomb to hit away from target.

Laser rockets are now obsolete because of this bug 

[Napillo]

One thing I noticed, is that the tgp aligns for a while if you leave the radar off after takeoff, not sure if this is intended.

The laser rockets should be beam riding, so you're likely not going to be targeting something behind you while firing rockets, they can't pull that many Gs.

No? You can even see the Sensor in the nose.

No but do Designation Turn after firing them to not overfly the target, which means putting it on the 3-9 Line or even a bit above that.

To be fair in case of rockets you would have to do a very sharp turn to put the target behind you before the rocket reaches it. With bombs it's a bit more visible because they are much slower.

Yes that’s how you do a proper designation turn  The Rockets do have a longer range then the Jeff LAR wants you to believe, though.

Did some moving target bombing runs today. The loss of stabilization is so bad that it will cause loss of track and you're lucky if you hit anything moving with a gbu.

Try doing an "area lock" and then slew the cursor on to the target. Seconds before GBUs impact the pod will start shaking but this will not affect the bombs.

Point track currently is unusable in some scenarios.

Just had the following situation: approach suspected sam site, observe missile launch, find rough area, put area track, avoid missile. Everything is fine at this point. Now second approach, tgp kept the target properly, find the sam vehicle, track it. Took some time so there's a launch from SAM, avoid missile, come back on course, tgp has lost the track, is currently looking at some random point in field.

Another problem that started showing up is tgp slave not working 80% of the time. That was in MP so I have no track files but I'll try to reproduce that.

I am aware of this issue, but it is indeed difficult to reproduce. I have experienced the same problem before, but it cannot happen every time. The probability of me encountering this problem is relatively low, only about 10%. So I am currently confused about the reason. If you can create a relatively clean TRK files, it will help to find problems faster. Thanks~

I've also experienced this, pod will lose point track when flying over a target (not masked), and suddenly jump to a location quite far away. This often results in a near-miss from LGBs.

Also please look at this, might be related:

Here's a track showing loss of stabilization/tracking when passing a target, and sudden jumps/erratic behavior of slaved target mode.
