Multiple LGBs in one pass?

[Seanner]

There seems to be either a bug in the game or poor real-life design with the TGP where it doesn't know/care it's slaved to the SPI. Steps to reproduce:

 

1. slew pod somewhere or boresight it with china aft...just make sure it's away from the steerpoint so you can watch it change

 

2. make the steerpoint the SPI with TMS long aft

 

3. slave all to SPI with china long forward

 

Upon completing step 3, the pod (and everything else) will face the waypoint.

 

The problem with the above is that you can't lase the target for more than a second or so (if at all, maybe the indicator erroneously flashes), yet if you designate the TGP as the "master" SPI as an extra step 4 with TMS long up (instead of having it slaved to the exact same point after step 3), the laser works.

 

This means it is not possible to use LGBs in the same way people have figured out how to use multiple IAMs, unless you can slew manually REALLY fast.

 

The goal is to cycle mark points with the HUD as SOI while you continuously lase, and the LGBs, if dropped sufficiently apart, should have time to hit multiple targets.

 

A second problem I found while researching this is that the TDC doesn't always slave, e.g.

 

1. TMS long forward the TDC and slew it somewhere

 

2. china long forward so the TGP looks where the HUD looks

 

3. make sure the HUD is SOI and now TMS long aft

 

The TDC stays where it is, but if you change the SOI away from the HUD it slaves...until you give SOI to HUD again, where it will reappear in the pre-slave position. It sounds like a helpful feature almost, but it's inconsistent as the TGP doesn't do that. Bug or real-life design?

Set latch on, nudge TGP cross-hair onto target with slew control and activate laser.

[Seanner]

Yes that or TMS forward long works fine for one target...

 

How is one supposed to take on 4? It's not so easy to slave it back to the mark, change the mark, then re-bandaid-fix the TGP. Now if I had the real HOTAS maybe, but the X52 requires mode switches to have the full # of hats and it's very time consuming to do those steps that SHOULD amount to merely changing the mark...unless it shouldn't which is why I was asking if it's a bug or true-to-life.

You're not supposed to ;)

You're not listening: You need not set the SPI again with TMS Fwd Long.

 

Slave TGP LOS to Steerpoint. Now toggling between mark-points will automatically adjust the TGP LOS accordingly.

 

All you need to do now is nudge the slew control and lase (half a second at most).

[Seanner]

But when you slew the TGP it is no longer slaved to the mark. The idea is to mark 4 targets with sufficient spacing to where slewing all 4 would take too long. If you slightly slew it, sure you can lase the FIRST one, but I already know how to do that.

I'll try one last time:

 

Target A,B,C and D designated with markpoints A,B,C and D.

 

Set steerpoint dial to mark and slave TGP to steerpoint. Will automatically snap to A.

 

Now to start lasing you nudge the slew control (Think of it as a fine tune as your steerpoint will seldom correspond 100% with the target) to put laser designator on target.

 

Impact on Markpoint A.

 

Now toggle markpoint to markpoint B via HOTAS/UFC. TGP LOS automatically snaps to B.

Same with C and D.

 

As per the above, at no stage do you redesignate SPI nor do you slew TGP from A to B et al.

...

 

Now toggle markpoint to markpoint B via HOTAS/UFC. TGP LOS automatically snaps to B.

 

This is where we are disagreeing. If you can explain how to slew the TGP while somehow keeping it slaved to the selected markpoint, I will believe you. The instant you nudge/slew/whatever it from the first point, it is no longer slaved and will not snap to future mark point changes.

Apologies - My bad: Should have proof-read prior to posting :)

Alright thanks we agree now. This ends up being too much for my X52 stick to handle however :(

[SimFreak]

I'm not sure what's being asked. LGB is guided by a laser. So if you release pair, both bombs will be guided to the same spot. If you delay release of second bomb, that bomb probably will not have enough energy to switch to other target..especially since it's coming off slow aircraft. How many seconds will it need to change its trajectory?

Now this issue is resolved I will jump in. Seanner seems to be talking about having 4 LGBs in the air simultaneously chasing different targets while cycling the laser POI. Viper seemed to be talking about doing it one at a time, but it was not clear to me. Can someone clarify this point for me?

EDIT: SimFreak sniped my query. Looks like we both want to know.

Yeah I'm looking to take out multiple targets simultaneously, similar to the thread and associated video where it's done with JDAMs.

 

According to the also realistic but old DOS-based Tornado flight sim (we need DCS: Tornado please...), 4 seconds or so between bombs is fine. There're missions where e.g. you take out 4 adjacent HASs from FL250. So yeah, not so much spacing as I would like between targets (may as well slew...and it's the only way in that game), but I can't even take out adjacent trucks with slewing with a 6+ second bomb interval in the A-10. No trouble with the first target of course...

[BiPod]

Thanks Seanner. I am under the impression that the A-10 can only attack one target at a time with LGBs, but I'm not sure, so I will keep my mind open.

...LGB is guided by a laser....

 

LGB follows a dumb-bomb trajectory to hopefully somewhere within the Weapons Basket where it will pick up the reflected laser energy prior to impact and only once reflected laser energy picked up will it guide to it's target. In theory you would probably want 15 secs between bombs with targets spaced relatively close together, giving you 5 secs to paint new target while still giving second LGB time to acquire the second target's laser energy and so forth.

 

I attempted to explain the theory of getting the laser to fire to the OP. LGB's are just not that smart, especially not GBU-12's, hence the use of JDAM's for multiple target prosecutions.

Just found this. Post 11 suggests you can do it with 2 LGBs with 8-10 secs spacing. This was in a Beta.
