investigating BOMBS deployment is extremely bad because of very inaccurate aiming calculation

[Kuky]

Beside the cannon on the MIG-29A Fulcrum module being bad I can see that deployment of bombs (all kinds) is extremely bad as well, I have tried RBK, KMGU, FAB & ODAB (or maybe the last one has a different name, I can't remember now but its not relevant to this issue) and all of them drop way too short of the aiming point on the HUD... I mean all of them, all the time. I thought maybe its the map issue somehow (maybe terrain elevation is off on some maps) so I tried Caucuses map also and I can see the same thing.

Another issue I found was that when switch is in ALL position (to drop all bombs of the same type at the same time) in case of KMGU bomblets canisters only 12 of them drop from 2 inner canisters at the time, so in order to drop more of them you have to quickly press the weapon release button again and again in order to release 12 more, then 12 more again etc.

I believe these canisters should drop whole 96 bomblets in one go (which is perfect for targeting columns of vehicles in straight road) and when the switch is in ALL position it should drop them all from all 4 canisters... but it doesn't.

I also have bong in-accuracy and this is off topic, but you know you can correct for moving targeted with pre-designation

Predesignation also falls short.

Not so bad than CCIP but is also inaccurated.

I tried several different ways , but - short. If you set the QFE of the target, the "ОТВ" indication appears, with minimum range values, and the lower distance mark depends on the QFE of the target. Changing the QFE of the target to QNE leads to better accuracy, but the "OTВ" is turned off even at the ground itself. If you have not set the QFE as the target and the current QFE is below the height of the target, you are constantly "OТВ" and you cannot use the weapon at the target mark.
 

Update: Some videos of marker position depended of QFE. I think it would help to find issue.  What is 'zero' altitude for target ?

Have you tried to find the barometric altitude of the target in QFE at which you will hit the target? And compare it with the altitude of the target itself, is there a big difference? You can look at the post above to understand what I am talking about

Guys shouldn't the target's altitude setting be ignored all along with laser rangefinder working? There is no mention of it in combat employment manual, and, say, in MiG-21 target elevation is only needed when radar rangefinder is off.

Nah, thats not it, not in the quick mission I tried this and where track is from, anyway... the targets are on coastline flat area so maybe few m difference at most, which should not be the cause of it. My guess is, looking at that screenshot of HUD, that aiming reticle and line are shifted above horizont line, I think the top of the line should be level with aircraft line, not anove it, and if you shift that line down to the aircraft line on the HUD the aiming circle comes right above the area where the bombs actually hit.

EDIT: ignore the crossed out part, I realised what I wrote and thought was the issue, makes no sense so just ignore it

Yes, good point
