On the Range #58 - Multiple GBU-38 Releases in the DCS: A-10C Warthog

[@cbremer83]

Just getting started in the A-10. Been away from sims for a few years. While doing some RTFM I was thinking this would probably work. So I googled it looking for vids or writeups on this topic. And here I am. Now that I know I had the right school of thought, it's time to try it myself. Thanks for the vid!

[@MrSniffleChihuahua]

Thanks for sharing this method! Could be a big timesaver.

[@nightman7263]

Good one! Ideal would be have them droping at the same time and each one go after its own target.

[@joemacneil2]

Oh man I was wondering how to do this and of course Bunny already had the video out, thanks!

[@revenger681]

What map is he on? Such a nice desert area. Whenever I create missions the targets spawn hidden in trees, or around houses, lol. I can never see them or spot them.

[@ajobis1881]

Where do you find the maps that show where the battle lines are? I.e. FEBA. Is there an available download or in game reference? Thanks!

[@CODMODDERZ360]

How do you set the mark points as the SPoI or do they automatically become it as you place them?

[@4023446]

+Dr Dwe It is TMS aft/long to get the steerpoint back as SPI.

[@jowenjv4463]

+Dr Dwe I never use this method to set SPI, usualy i'm only with the TGP as SPI, and Markpoints are for bad weather. It seems when the HUD is in SOI, the steerpoint your sensors are looking at are directly set as SPI. But i could be wrong.

[@pitbullvicious2505]

Hi Bunyap. Do you have any rule of thumb for how far off the ASL can be from the pipper with the furthest target for this to actually work (I guess this also depends on the altitude)? I'd imagine you'd like to set up your run so that you'd minimize that spread as much as possible of course, but how do you judge if the targets are not spread too far apart from each other for this to work? Or is it just matter of practising it and getting an intuition for it?

[@tommeier1888]

+Pitbull Vicious Dont mind this comment just wanna know

[@jowenjv4463]

+Pitbull Vicious I'm wondering the same thing. At the release of 2nd 3rd and 4th bombs, the ASL is way too far for me. But remember he is at a good altitude (+15 000ft it seems), so the JDAM can correct this offset. And if bombs are released, it is because LASTE (LASTE, CICU or IFFCC, i don't know which systems allows or inhibit weapon launching) have allowed their released. I mean, look at AGM-65, when you havn't a good track, it says ''NO TRACK LNCH INHBT'', and same thing with the canon in standard cueing system (not the 4000/8000/12000 one), it will indicate ''CCIP ERROR''. Even with dumb bombs in CCIP Consent to Release in 5MIL mode it will not let you release your bombs in some conditions. So Actually, even if the reticle is far of the ASL (until a certain distance limit i think), LASTE, IFFCC or CICU will consider that its still in a good release condition.. But in bad weather condition, i think it can be more difficult to accuratly hit targets (like MBT) with a so important offset, due to the wind effects. For me, planning a specific route to align (if possible) each target with the others will be a better option.. But lost of time in some emergency conditions (like if fast JTAC support is needed).

[@pitbullvicious2505]

+Johan G.Bruère-Dawson Indeed, to my understanding too, the plane's systems should inhibit the release if the JDAM can't reach the target. And this, as you state, is dependent on weather, altitude, etc. My question may have been a bit badly formatted. What I was trying to ask is if Bunyap (or anyone else) has any rule of thumb how to judge before the run if the targets are near enough to each other to ensure that all of your drops will be allowed. To use the video as an example, I hadn't realized that the system would allow dropping JDAMs with as big of an offset as seen with the pipper and the ASL (very briefly) in Bunyap's video @2:32 with the mark point D (this is just due to my lack of understanding, obviously). Or if there is no other way than to simply practice, practice and practice until you get a good intuition about this. As a side note, I think that JDAMs in general are a weapon you'd use if you have enough time and in emergency pilot's would rather use their gun or dumb bombs (I think Lt. Col. Olson mentions this in his interview that can be found at the ED forums).

[@jowenjv4463]

Pitbull Vicious Ok. Yeah i've listen to the Lt.Col Olson, it was very very interresting. I don't know for the rule of thumb, interresting to know in fact

[@reyco1987]

just curious, how would your accuracy be affected if you didn't actively lase when you created the mark points??? I feel like it wouldn't be a huge deal...

[@pitbullvicious2505]

+reyco1987 Check his previous video (link in the description) :) He just had a tutorial on it.

[@reyco1987]

Yea, I'd already seen that as well, I know lasing is supposed to make it more "accurate" but I'm just curious the difference it really makes not lasing...

[@pitbullvicious2505]

+reyco1987 OK, sorry for butting in... If you are willing to accept my explanation of it, I believe it is dependent on the angle where you set your mark point from and the surface altitude in your plane's systems. How I understand it works is that your systems know your plane's position in space, the ground level altitude for the location you are at (and trying to set the mark point to) and the angle of the TGP camera. It then calculates a straight line from your camera based on these data and places the mark point to the x,y,z coordinates where that line intersects the programmed ground level (which in general should be quite close to the actual ground level). As human made objects (especially mobile ones) are not included in these data, the line does not intersect them in your systems "mind". Now if that angle is very low (you are relatively low and far away from the target) this line will "go through" the target and intersect the ground level behind it (from your perspective). I guess the distance can be anything from few meters to several hundreds of meters, depending on the angle and where you are aiming at and what the ground profile is. Plus of course there is the errors from your location, the angle and the ground level, which may work to your benefit or against you :) If you are straight above your target (your laser and LOS is nearly perpendicular to the ground) the error will not be that bad. When you add the laser measurement to that, the systems will know how long the line is supposed to be and can then add that to the equation on calculating the x,y,z coordinates that you as a pilot are trying to set the mark point to, resulting more accurate mark point coordinates.
