GBU10/12 Laser time problem

[Davros23]

Hi all,

 

Quick question. Starting to learn the (very basic) ropes with the GBU ordnance mainly by following the tutorial in PC Pilot. Setting up DSMS profiles everything seems very straight forward, selecting the specific bomb types, selecting view pro, CCRP, selecting change settings, auto-lase, but the problem comes with setting the laser time. I'd like to set the time to 10 secs but when I try using the UFC then hitting the laser time OSB nothing happens, any ideas?

 

Cheers in advance for any help. I'm sure there's a very simple explanation :)

try hitting the CLR (clear) button before the 10 and then the OSB

[Davros23]

Thanks Blooze, I'll give that a shot.

Can you see the digits "10" in the scratchpad? You could also try using CDU buttons for the input.

[Davros23]

Umm, good question. I was going to ask where the sctratch pad was (in F4BMS it's displayed on the DED below the HUD, I was looking for somewhere similar). Quick search reveals it displays on the HUD itself and CDU I believe? I'll check later but this would normally be clear, correct, there should be no reason to CLR it first?

[FreeFall]

There may be a "Note" on scratchpad. Cannot tell what happens if there is something because I always clear notes or errors before inputting anything.

[Davros23]

Thanks guys, I'll let you know how I get on.

[WildBillKelsoe]

Use the CDU instead, or you can use they normal keyboard combo Fn + Lctrl + 1-0 on numpad. I do it the latter, even with texts.

[Davros23]

Thanks all, got it working, pressing CLR first seemed to do the trick.

Semi thread hijacking.

 

Are there any guides out there as to when one should fire the laser? Maybe a scale of some sort?

 

I understand ~15 seconds before impact is recommended for bomb release at 12,000 to 15,000 ft. However it seems to be a hit and miss for me.

 

A lot of the times the bombs waaaaaaay overshoot my target. Sometimes I lase instantly and it falls on target. Turn around, do the exact same and I completely miss. Can't really see a pattern here...

 

Any help appreciated.

 

Cheers

10 secs at 12,000 ft and you'll never miss. Are you sure you don't turn too quickly and maybe mask the laser?

[Blooze]

For GBU10s and 12s I have been using autolase ON and setting the timer to 12 seconds and get very reliable results regardless of altitude.

[NhiTrac]

Cheers guys I'll give 10 to 12 sec before impact a go.

 

And I'm certain the laser isn't being masked as I fly dead straight until impact.

[Davros23]

You've got autolase set to ON NhiTrac?

[NhiTrac]

You've got autolase set to ON NhiTrac?

 

Havent had the time to try it on 12 sec as suggested above, though I've tried it with autolase and manual lase.

[NhiTrac]

Thanks for that. I'll give that a go over the weekend too. Btw, if you're selecting lase at 30s before impact, what happens when the impact time is less than 30s? E.g 8000ft should be less than 20sec before impact I think.

 

Ps. I'm a bit confused after RTFM, page 552:

 

Tip: for best accuracy, start to lase the target 12 seconds before impact.

 

Page 556:

 

Tip: For best accuracy, set this to 8 seconds before impact. If set to 0, the laser will default to firing 4 seconds before impact.

 

Given second talks about auto lase, I thought it'd be the same?

 

Edit: Page 559:

 

Note: To improve accuracy, it's recommended that you deliver these bombs from above 15,000 feet AGL and delay lasing the target until 8 seconds before impact.

 

Truly confused :helpsmilie:

Hey Trev,

 

Why don't you just edit the default profile?

It will apply to every GBU-10/12. It's much faster then creating a new custom profile.

 

I can't even recall the last time I selected a station in the DSMS btw.

[Dejjvid]

Regarding lase time.

 

Default release WILL overshoot the target if you don't activate the laser.

IF you are engaging a moving target you should activate the laser at minimum 15s depending on altitude.

 

The most flexible way is to ignore auto lase and enable LATCH in TGP CTRL page.

This way you enable the laser with a simple push on NWS and stop it with the next push.

Very very convenient, and flexible.

[Davros23]

Good info, thanks Dejjvid.

Whenever I edit the default profile for some reason the impact keeps switching back to to CCIP and I hate that.

 

It only jumps back if you select your weapons with the buttons in the DSMS page. This will create a new profile, which is CCIP by default.

[KaspeR32]

I am paranoid about forgetting to stop firing the laser. In the systems I fly IRL I can't forget because I have to hold a button down the lase and it's an old skool guarded square push tile switch and it hurts after a while.

 

If you don't select LATCH in the CTRL page of the TGP, you will have to hold down the NWS button to lase the target. Once you let go of NWS, the laser will shut off. You can only forget to turn it off (which I have) if you turn on LATCH, and therefore have to press NWS twice. So the default set-up (NO auto-lase, NO LATCH) might work best for you.

 

Also, I didn't realize I can start lasing from only 8 seconds till impact. I usually start at 15, even on a stationary target. Good to know :)

[NhiTrac]

Think I know what I'm doing wrong... Not lasting when making a target my SPI.

 

Carried 12 GBU12s to practice first two completely missed, after I started lasting when marking a SPI, they all hit. Even at different altitudes.

 

Could this be it or just coincidental?

[Nu-NRG]

Some stuff:

1. You NEVER ever select a station on DSMS. You ALWAYS employ weapons trough weapon profile.

2. GBU-10/12 should be lased in between 13-15 seconds.

 

Now on to the lasing it's self:

You can set AUTOLASE to ON in weapon profile along with desired lase time.

The alternative is that you manually lase your self with pinky button - with latch on or latch off.

SPI has no effect on lasing, laser will always light up a target that is in the TGP's cross-hair.

 

Also, keep in mind, laser in the TGP will burn out after X minutes (I tested it but I forgot the exact number) off TOTAL time used (does not need to be continuous)
