Its noting that you have no SPI anymore isn't it? I think this has to do with how the CDU purges its navigational data on touchdown. If you notice after the CDU resets to its Warm Start state you are no longer in Flight Plan mode but instead are now in Mission mode. If your SPI was slaved to your Steer Point then that would be why there is no more SPI, or something like that.

 

No doubt Noodle knows why and probably has an explanation thats actually true and not just conjecture like mine.

Note indicates a message through the Datalink, usually a 9-line from a JTAC, but also a Message from another pilot is possible...

RMFCD look for the MSG button. Shows the Message received.

Use the ACK (acknowledge) button to clear it.

Other possible sources for a note indication are EO-Time of MAVs, or other system messages. Use ACK to clear the indication.

TMS Left Short will also clear it.

[wolfstriked]

Thanks fellas.I think I have tried hitting CLEAR and TMS left short with no effect.Too tired now but will try again tomorrow and see if I can make sense of it all.Funny thing is my last mission I ran into something that makes wondering what the NOTE is all about seem trivial.I was attacking some targets and suddenly I had no weapons anymore.Outside view showed they were all still on their pylons but DMS had red circles around each store with nothing listed at all.Never seen that one before which prompted me to realize its late and I need sleep.:joystick:

Since I've got proper(-ish?) dumb and smart bombing completely covered by now I'm focusing on CBUs. There's a document containing the CBU 87's footprints as a function of HOF and RPM, which I find very handy bit of information. Does such a sheet also exist for the CBU 89? And what other parameters besides HOF affects a CBU89's footprint?

Or am I asking the wrong question(s) because perhaps footprints are totally irrelevant in employing CBU 89s and I should focus on other aspects?

[Eddie]

DCS doesn't model CBU-89, sadly. Do you mean CBU-97? If you do, set HOF to 700 (900 on very uneven terrain) and forget it

[JayPee]

Sorry, meant 97 yes. What will that setting result into then? In terms of effectiveness, dispersion, area coverage, etc..

 

Reason I ask is because if I set HOF to 700 for a 87 I can still choose between an area of 18x18 metres up to an area of 396x320 metres, depending on RPM setting.

The footprint of the 97 is not depending on the HOF. The deployment of the submunitions is controlled by the 97 itself and covers a fixed area of, iirc 300x300 ft. HOF only influences the time the submunitions descent on their parachutes. (but: the higher the HOF, the more time the submunition spends on their parachutes, the more they are susceptible to the effects of wind! Therefore, set the HOF as low as practicable possible)

 

Search the forums and or google for the CBU 87 and CBU 97 to see the differences in function - this will make things probably a bit clearer. :o)

I did look up the functional differences in terms of employment mechanics but honestly that didn't give me an indication of how to control for footprint area in case of the CBU 97.. I'll look up the differences again and while at it will try to confirm the 300x300..

After looking for it by myself ... I might be wrong with 300x300. This brochure of the manufacturer speaks about 800x800: http://www.textronsystems.com/sites/default/files/pdfs/product-info/blu108_datasheet.pdf

 

But nevertheless, the covered area is not configurable for us. The basic idea is, that the "smart skeets" search for targets actively and it doesn't matter if these are 10 ft or 100 ft apart - the deadly effect would still be the same (as long as the target dispersion is within the maximum coverage area of the said 800x800 ft).

Indeed it seems so. I also read the 476 factsheeit on the 97 and there too it is said that HOF does not influence footprint/spread.

 

But, what does HOF influence in the case of a 97 and why would I change it and/or stick to Eddie's advise of setting it to 700 or 900 in case of uneven terrain?

The HOF determines the height over the ground when the CBU releases the submunitions (BLU 108) which then descend from there on their parachutes. The earlier/higher above the ground this happens, the more time the BLU 108 will spend on the parachutes and therefore wind can longer blow them off their target beneath them. Because of that, you will want to minimize the time on the parachutes, i.e. reduce the HOF as much as possible. But if you set the HOF too low (i.e. 300 ft), it can happen that the remaining height above the ground is not sufficient for a proper deployment of the submunitions and/or the skeets. A low HOF is also problematic if the terrain is uneven as then the above also applies ... to at least some of the submunitions (some BLU 108 have 700 ft air beneath them, some only 300 ft --> half of them will be duds)

Right! So the only reason to alter the 97's HOF is to find the proper effect balance by taking into account both wind and terrain relief.

 

By the way, did you test the 820ft by 820ft as written in the brochure? If not I'll test by throwing a 105 exactly in the middle of a 820x820sqft field full of T80s using 700ft HOF with no wind.

Sadly the CBU 97 do not work as effectively as in RL. See here for a discussion of the problem(s): http://forums.eagle.ru/showthread.php?t=124673

 

Basically, you will probably manage to kill 1, perhaps 2 T-80 with a 97 ... or maybe 3-4 T-50 although they supposedly kill something like at least 5-7 (or more in case of older tanks)

[JayPee]

Yeah I know about that thread and the ineffectivity of the modeled weapon. However by placing tanks on the perimeter of the 820x820 square and by making sure I set the SPI exactly on the intersection of the diagonals I think I have a pretty decent measurement tool.

Hrm, yeah. Try it - would love to see the results as well! :o)

[JayPee]

As promised. Made a square of 800ft by 800ft and placed a total of 10 Abrams' on the perimeter and one in the middle. I tried it once with a 97 and once with a 105. Both times from a 7,500 AGL delivery altitute with a HOF setting of 700. Did the 97 using CCRP, both times the centre tank was the steerpoint on which I dropped.

 

Both bombs seem to fall a little short, leaving the 'front' 2 tanks untouched but the remaining 9 all got hit. Sadly only 1 was destroyed in the first run (105) and 2 in the second run (97) but that's another issue.

[wolfstriked]

Hung store, probably.

 

Were you dropping JDAMs? If so, you probably made a "quick pickle", which means you didn't hold the pickle button long enough to complete the weapon release process. JDAMs can take up to 1.5 seconds to come off the pylon; you need to hold the pickle button until it does.

 

 

Every weapon was red though so the DSMS page only had the TGP and jammer as green.I had the default load out loaded.

[JayPee]

Within the cockpit, zoom in/out seems to alter the FOV instead of zoom like you'd do with a lens on a camera, is there a way to alter the pseudo zoom functionality by locking the FOV and have it zoom in/out?

[cichlidfan]

The zoom on a camera alters FOV as well.

[JayPee]

DCS A-10C QUESTIONS

 

Yes the diagonal FOV in a circular lens. The game changes the horizontal FOV in a rectangular frame, effectively changing height/width ratios of objects..

[shagrat]

Erh, yeees... if zoom in (watch a smaller part of a scene just larger) the angle between your focal point and the part of scene (aka FOV) is smaller...

Do you mean the 6-DoF axis to move your "Virtual Head" forward?

[JayPee]

No, I do not mean the Z axis shifting forwardd and backward, I mean zooming in and out.

[cichlidfan]

effectively changing height/width ratios of objects..

 

I don't recall ever noticing a change in aspect ratio when zooming.

[shagrat]

No! It does exactly what a zoom lens does... or a fisheye lens when "zooming out".

EDIT just with out the focus effect. On the PC everything is sharp, usually.
