Gbu-12 missing targets

[clanitho]

Hello,

 

is it important to enter the laser code after selecting the gbu-12?

I ask this question because since 2.51 my gbu-12 systematically miss their targets of a few meters.

Everything is ok on the 2.5.

Yes, you will need to manually change the laser code once airborne. The Harrier's laser code is automatically reset to 1111 when ever the wheels are on the ground, so even if you set it and then land, you will need to reset it to use whatever laser code the bomb is using once you are in the air again.

Why does it matter if it is the tpod that is doing the lasing? I mean, if the tpod resets to 1111 then won't the bombs reset as well. So long as they speak the same language and not dealing with jtacs, all should be good, right?

That would depend on how well the targetting computers communicate with the bombs that are loaded. Common sense would dictate that indeed, laser codes used by the TPOD are transferred to the bombs so that their seeker heads know which laser frequency to look for.

 

In other aircraft that do not have a TPOD, the laser code has to be specified in the mission editor (in this example, the M-2000C):

 

 

 

But for the AV-8B N/A, there is no such option.

Also, Clanitho didn't specify under which conditions the GBU12s were dropped. Was a different mission used for 2.5 and 2.5.1? JTAC unit on the ground, a Predator drone doing auto-lasing, TPOD?

For me, dropping GBU12s works just fine in 2.5.1 but I tend to use Predator drones for lasing.

There is no communication between the aircraft and the gbu-12. The laser code is set on the ground on the seeker itself. The game allowed us to change it it the cockpit to be convenient.

Ok, thanks for the info ! :thumbup:

Thanks for your response, the problem was my aircraft speed , too fast.

[davidp57]

What's the max speed for dropping a GBU12 ?

I stay below 350 knots.

[olivier-gaming]

and at what altitude? if you are too low and too fast your laser no longer marks the target

[olivier-gaming]

I tested GBU12 at 17000,20000,25000 and 30000 fts and a speed 519 no problem the target was destroy

[clanitho]

and at what altitude? if you are too low and too fast your laser no longer marks the target

 

Above 9000 ft.

[olivier-gaming]

Above 9000 ft.

 

Do you start plane in the air or on the ground? because if it is plane in the air the laser code does not take on tpod

[sunski34]

I had a problem when lasing EWR 55G6 (spot on the vehicle) with TPOD, GBU doesn't hit it. Seems to lase head of antenna !!!

 

It's ok with shilka, so it depends of the target I think.

I start from ground and my target is a EWR 55G6.

As suggest sunski34 i will try with another target.

You mention the bomb is missing by a few meters, how much is it missing by? If it is within 5 meters, it should be normal. Is it suppose to be like that in DCS? Not sure, but sounds within limits of RL. Also, are you turning after bomb drop? Why does that matter? In DCS, I don't know but in real life you want to lase the same side of the target that the bomb is coming from so it can see the laser illumination, so you want to drop the bomb and turn the aircraft so you can maintain the laser on the side of the target that the bomb can see.
