CBU 97 falling short A-10A

Witchking · November 12, 2012

Hey guys,

I have been trying out the CBU 97 and it always seems to fall short of my target. I set a CCRP point...then press o and then pass over the thingy....then it will release...but then it falls short

See the smoke...there are targets...I dropped the CBU (CCRP or CCIP) and then notice where it exploded...the grey smoke.

What am I doing wrong? Is this a bug?

thanks,

V

The 97 is very prone to winds as it uses parachute deployed canisters that spin up and deploy target aquiring skeets that fire shaped sharges onto their target.

Come to think of it, FC2 did not have the "new" 97 functionality that DCSW has, so you might not be used to this behaviour.

Use the CDU to correct for wind..oh wait.

yeah...come to recall...even when I tried it once in DCS A-10, it fell a bit short. I guess I didn't use the WDM version. But currently, I am trying it in the first A-10A, F-15 mission and I am always short...no matter what approach/CCIP/CCRP that I use. How do u have to employ these bombs then? is there a proper way to correct for the wind in A-10A?

Lets see the track..?

Witchking · November 13, 2012

Hi,

Here is a track of a try I just did. Bad try though...lol...got shot and limped back to base.

ANyways...mission start time around 9:10, and I used the CBU around 9:14. Notice that I target on the road... I fly such that the box is pretty close to the centre line and even then...the cbus fall short.

thanks,

V

Other other note... bugs found...even when I lost both my rudders and hydraulics...once I landed I was still able to control rudder. it turned as if the rudder was present. Secondly, there is no intense yaw or compensation that I needed to do inspite of shutting down one engine. In DCS A-10C, I need to have constant rudder input or something or else..the plane constantly skews to one side.

CBu fail.trk

well of course your going to be-able to turn, it's using the front wheel at this point, more than likely not effected by damage, due to the rudder is at the other end of the plane with the damage?

Witchking · November 13, 2012

opps...sorry...thats fair. completely forgot about nose wheel steering. lol

Hi Witchking,

I can confirm that.I shot them over 5K.Same dust/ smoke.So it's a bug i guess.We should report it.

Witchking · November 13, 2012

glad to hear. I knew I could be just bad...but not that bad. :p

Witchking · November 13, 2012

Anyone else find that they can't use the CBU either? or can anyone actually use it properly in 1.2.2?? Is this an actual bug?

I'm having the same troubles with CBU-97 (A-10A, FC3). I drop CCIP at 1000-1300ft in a shallow dive and can't do any damage. I actually double checked my loadout to make sure I wasn't carrying training shapes, because all I saw was a couple plumes of grey smoke with no explosions or damage to targets.

JABO2009 · December 11, 2012

can confirm this.

The A10A CBU-97 drops go definately short.

silentbob11 · December 16, 2012

can confirm this.

The A10A CBU-97 drops go definately short.

as are the A-10C CBU-97's. it used to be OK in previous versions though, so it must be a simple bug to fix.

cause the problem still occurs for me

min alt to drop them is 6,000feet.

skouras · August 3, 2013

go for 8.000 feet and above

Is there tutorial / guide for CBU97's? I've tried CCIP under 5Kft and I never get an explosion... just puffs of grey smoke. Sounds like I need to be over 5K ft and maybe using CCRP?

A guide (that applies to A-10A FC3) would be GREATLY appreciated... maybe even a youtube video with FC3 AFM A-10a... (anyone!!??)

this is just a demonstration with some tests that this guy doing

i think the CBU97's is still falling short or something

Apples · August 5, 2013

It is falling short and its annoying. Explosion's still look like something from a 1980's cartoon to!

Witchking · August 5, 2013

Well...Mastiff's video shows that they can be dropped correctly. I don't know how to recalculate the systems to consider wind. I know that it works well with A-10C, but even then in heavy wind situations I have had the CBU 97 miss.

Home Fries · August 5, 2013

It definitely seems that they fall short, but if you understand how the CBU-97 works then this may only "seem". It may also be true, but after the following description it is not so obvious.

If you're concerned because the puffs of dust hit the ground behind your intended target, these aren't the submunitions hitting, but rather the bomb casings, which are ejected at burst altitude and then become high drag particles that won't follow the standard parabolic bomb arc.

It's at this point that the BLU-108 does its thing, as the submunitions deploy drag chutes to point down, then engage a rocket motor to climb vertically in order to search for targets. If targets are found, then they engage them with a kinetic sabot. This is also why the explosions often follow the puffs of smoke (casings) after a number of seconds.

The big question (for the A-10A) is: what is the burst altitude for the CBU-97 defaulted to?

Yes I agree. If the A-10a does not have all the complex settings for the CBU-97's we should at least know what they are set for so we can plan attacks accordingly!

Seems like there is no burst altitude for CBU-97 applying for A-10A, alike it was in FC2's bomb table script - 4 sec. delay only before submunition disperse...

And, of course, absence of WMCD makes bombing run more unpredictable, compared with A-10C systems. / CO mod OFF/

Ballistic computer in FC3 calculates impact point for ordnance assuming that weight and air resistance of the bomb will be constant on whole trajectory. In the case of the CBU-97 - bomblets, after separation, actively slowed down by rocket boosters and then descend by a parachutes.

FC3 script simply calculates and displays the impact point of a dumb bomb. IMHO.
