GBU-12 3/9 way off?

[majapahit]

GBU-12 3/9 way off?

 

for instance

instant action - Georgian foothills (start nice high altitude)

active pause On

set TGP to 2/supply

POINT to 1 of truck at 2/supply

 

set CCIP consent to 3/9

 

select GBU-12

in CCRP mode / misses by 90 feet edit<< i mean CCIP mode of course

in CCRP mode / misses by 90 feet

 

?

what am i missing

 

BTW outside F6 (Ctrl?) GBU-12 missile view: still shaking, GBU-38 still not (doesnt miss either)

 

1.1.0.7 fresh full install

Did you activate laser either manually or program for automatic mode?

Oh and CCIP consent mode shouldn't effect CCRP anyway since CCRP is 3/9 anyway IIRC.

[WarriorX]

At the risk of stating the obvious, you do not mention lasing the target anywhere in your description.

 

I drop my GBU 12's from high altitude (>15K), use CCRP, and lase the target for the last 10-12 seconds.

[WarriorX]

Sniped by my friend from Germany!!!

[159th_Viper]

SPI?

 

Your original post illustrates well the necessity of always providing a track with potential issues that need investigating.

 

Please do so :)

I'll try lasering

shouldnt this be AUTO by default (read this somwhere?)

[MTFDarkEagle]

Nope, isn't set to auto by default.

[majapahit]

OK, autolasering is OFF by default, oopsie

 

anybody care to report the exact sequence how to 3/9 a GBU12?

 

I laser 'somwhere' with the taget in sight,

and keep my finger on the Laser INS button

 

I point the centre of pickle (dashes) on the target

push release

dashes go to line & a timer comes down the pole

 

eh, am I supposed to keep the centre of pickle on top of the target all this time? (with timer racing down)

probably, but somehow this defeats the purpose of 'automatic' release

 

.. and still misses by 30 feet (which is 300% better than 100 feet:smartass:)

[WarriorX]

Just a FYI majapahit, the GBU12 and 10 are both terminally guided to their target by a laser. They are known as LGB's or Laser Guided Bombs.

 

Your job as pilot is to set them up to drop the bomb on a ballistic trajectory that will send it close to the target, and then fire the laser.

 

The guidance unit uses fins to steer the bomb on to the reflected laser energy.

 

A quick google search will provide a much better explanation than I can.

Did you try the Precision Guided Munitions Training Mission?

As DarkEagle pointed out the Laser is not set to Auto by default. You must change it from the DSMS INV page. Or, if you want to manuallly lase it (as I do myself) you need to set the Laser to Latch On. If you don't do it, you'll need to continuously press the NWs button to lase the target.

To set Laser Latch On, go to the CTRL page on the TGP and on OSB 8 (i think) you'll have the option to set Latch On. Press it, go back to the TGP main page. When you press the NWS button once, it will turn the laser on. When NWS is pressed again, it will turn the laser off. Very useful for attacking AND taking measurements to targets.

long time ago, and confusing

(wasn't Laser 'AUTO' then? ~beta4/5)

aha,

clever

if this works I have something to figure out

thx

[WarriorX]

dont get hung up on whether the laser was or wasnt AUTO before or now, just go back and work throught the tutorial, watch Headspace's video, and RodBorza's advice.

say nasty Sergeant Loudmouth

 

you know John Wayne died rather horribly after an exposure to nuclear radiation on a very bad set of a Howard Huge movie

 

there's a lesson back to you :megalol:

majapahit, dont bite the hand that feeds you!

[roob]

 

This might help!

[majapahit]

figured it out

was missing the laser button

 

in instant action I can now make a Stuka dive

have the target 'somewhere' within the recticule, laser, boing

 

great fun

thx

If you're using LGB's, you also need to have a TGP loaded to lase the target. Try using this to designate your target and set it as SPI. Then drop the LGB using the CCRP mode (can be set in the DSMS profiles page). If you do this, you can drop from level flight (actually, you can even toss while in a climb, although the A-10 lacks the speed for this to be terribly effective) instead of needing to be in a dive like you mention.

 

CCIP is much more relevant to dumb bombs with no targeting pod available. You then need to acquire the target withthe Mk.I eyeballs and take it from there. The 3/9 mode you're talking about (where you get the TDL and a countdown to release) is like a cross between CCIP and CCRP (although this hybrid mode is called something else, I'm forgetting what right now).

 

The concept of this hybrid mode is that you can "acquire" your target by putting the pipper on it in the HUD like in CCIP. However, this mode keeps your pipper glued to the bottom of the HUD so you can always see it (as long as you're in a >3 degree dive if I remember right) while in CCIP you may need to be in a steep dive to see you're pipper.

 

3/9 vs 5 mil actually refers to the accuracy you need to place the CCRP marker through for the system to actually release the weapon (remember, you're only a voting member in the aircraft systems with modern aircraft). In 3/9, it will simply release when it is at the 3 o'clock or 9 o'clock position of the release point on the TDL. In 5 mil, the release countdown circle has a 5 mil ring on it and the TDL needs to be inside that ring when it reaches the release marker. 5 mil is more accurate, but slightly more challenging as well.

Question: Is it possible to drop a GBU in CCIP mode with no target formely designed? I mean, what I want to do is that my TGP designates the point where the CCIP reticle was pointing just when I press the delivery button on my HOTAS. Without SPI.

 

Regards!

I don't think the A-10 has a delayed CCIP mode...you can try using the HUD designator to quickly set a SPI, but that's not the same.

[Frederf]

A-10 has 3 CCIP release constraints:

1. Manual

2. Consent Release, 3/9 line

3. Consent Release, 5 mil

 

Manual is the immediate release classic CCIP. The CR modes are the visual acquisition/ CCRP release delay types. The only difference between 3/9 and 5mil is how picky the FCC is about your accuracy to command release.

Is it possible to drop a Paveway purely CCIP? Sure :) However if you want it to be aimed any where you still need to lase for it.

 

Here's a party trick method to drop CCIP Paveways.

1. Set IFFCC SPI

2. Slave TGP to SPI

3. Set TGP to SOI

4. Drop Paveway via CCIP and immediately tap down on the slew hat

5. Refine TGP crosshairs on the intended target

6. Begin lasing

 

That's actually pretty hilarious. Thanks for the nudge in that direction!

[rob10]

In 3/9, it will simply release when it is at the 3 o'clock or 9 o'clock position of the release point on the TDL.

 

Cool!! I wondered what the heck 3/9 in 3/9 release actually meant.

The A-10C targeting systems always designate markpoint Z as the weapon impact point (for the last launched weapon).

 

You could "quickly" load the Mark Z as the Steerpoint and Slew all to steerpoint and lase away. Quickly, here, being relative.. Of course, if you first set the CDU steerpoint selection switch to MARK mode...
