[REPORTED] INS guided munitions not working

[bdlarkin]

I have an issue with A-10C II where if I try to drop a GBU-38 or GBU-54 (with or without the laser firing) the solution offered by CCRP is bad.

 

 

It doesn't want to drop the bomb until the aircraft is directly over the target SPI point. The DLZ box is basically empty. Any bombs dropped from the MAN REL point are way to far past the target and just go dumb.

 

 

I set up a test mission and tried to use both GBU-38s and 54s onto some trucks at the center of the old airfield. Waypoint (target) and SPI is at the center of the airfield. You can see the time till in range for the bomb drop is the same as the time to fly to the waypoint.

 

 

I checked profile settings, and the like but I don't see anything different. Am I missing something? Anybody else have this issue?

Pretty sure ED are already looking into JDAM ballistics...

[bdlarkin]

Ok, I was curious because I didn't see anything in the bugs lsit.

 

 

 

Did something change between when Matt did his JDAM/L video (where it obviously worked) and now? Is this broken for everybody or just me?

[laertesson]

Yeah my -54s go dumb about half the time and all INS guided only want to drop really close even if I am high up.

[Scubamurph]

same for me.

GBU54's launch cue is too close to target so they overfly.

You are not able to pickle until man rel flashes up and it is too late.

 

For GBY38's the launch window is larger but they still miss the target by a large margin.

There is some kind of a problem with the GBU38/54 now.

I experience the same problems as mentioned above.

Today I was not able to release any GBU-54. I started a mission hot on the runway in Syria. I think I did everything correctly as shown in the video by Wags. But the bomb release didnt work.

No weapon release.

attached a few tracks

 

attached a few tracks

 

For GBU38 - seems like the range in the HUD is wrong - too long. Need to lunch much closer to the target + it less accurate than before in.

 

For GBU54- In case you've lased the target and stopped - it behave like a GBU12 - continue it's ballistic drop instead of aiming to the last point of the laser. So, incase you've started lasing - you have to continue until it hits the target. Else - it will miss.

In certain lunch profiles - if you lased and stopped - it will lose track of the laser and continue flying forward instead towards the target.

Just got the same problem...

 

 

I don't get that circle which looks like a pipper with the min and max range triangles at all. Weapon GBU-38 selected, in CCRP mode, SPI on target, can see the wedding cake in HMCS and on TAD. There shouldn't be more to it, or I'm just a bellend here...

 

And yes, Master Arm is on, having fired Mavs before in that very flight, sitting in pause ATM trying to figure what I'm doing wrong...

 

Edit: Disregard, I just couldn't see the new LAR symbology on the left side of the HUD against the horizon at all in early daytime from different direction (there's a reason I opened up that HUD brightness thread, it just striked up on me again in IA-A10CII-Caucasus-Easy Russian Foothills.miz), the pipper style thing is obsolete now, at least in the II. After watching portions of Wagses LJDAM video, I noticed the change and went ahead to drop from a shallow dive so I could see the LAR and range data, bomb just came off fine and hit.

You won't. The entire CCRP IAM mode has changed since A-10C I. GBU-38, -31, CBU-103, -105, -54 all use the new system.

[jppsx]

the problem seam to be that some bomb like the cbu-105 now need to be dropped basically directly on top of the target

[CANNOT REPRODUCE AND CORECT AS IS] GBU-54 and missing sounds

 

Hi Folks,

 

 

Not sure if i'm doing something wrong or not. The GBU-54 on Station 7 seems to miss the target everytime. I have no issues on station 5.

 

 

During the coldstart, there is no warning sound at the oxigen-test, firetest and wmcu (Preflight-BIT and in flight).

[Dragon1-1]

The "warning sound" is actually the landing gear tone. AFAIK, it should come on only when the gear light does. It's not a master warning tone.

 

VMU being broken had been reported. Weirdness with GBU-54 is also under investigation.

I am experiencing the same issue. Will provide a track soon.

[BIGNEWY]

Hi all

 

We have reported this to the team, it is related to some JDAM work being done at the moment by the team, hopefully it wont be long before you see the work in a public build.

 

thank you

CCRP/WCMD Issue

 

Now this may well be complete operator error, however I am having severe issues dropping either the CBU-103 or CBU-105 with CCRP on the A-10C II. I've noticed there is new HUD symbology. I've played around with the GBU-54 and the GBU10/12 and had no issues. I cannot get the WCMD to drop though. Any ideas or help?

Hitting target with gbu38

 

I tried too many gbu38's to hit a btr. One of them succeed and others missed. Can you watch the track and tell me what did I do wrong?

 

at my last try, I released 2 bombs and one them hit and other missed way too far, how?
