Illumination bombs

I have found out that if:

- you are using LysB, you can drop them only once per spawn. Clearing CK37, etc. does not help reseting the system. If you do not despawn, you will be unable to release after first drop.

- in RAKT mode, they seem to always fall short

- manual states that zone 1 ab should be used for m.9 delivery. I am unable to achive that mach at all in zone 1.

- manual states FALLD LAST should lit, it does not.

I did more testing to be positive that it's not pilot error, and ballistics are 100% wrong.

As it can be seen from the attachment, it is a stillshot of the trajectory where bombs deploy chute and stop advancing toward target (>15m/s descent triggers it)... it looks like as release point is calculated for the impact point with the ground and not the height over target.

Thanks!

My lysbomb don't drop at all. The Fälld Last light is blinking and no weapon is released.

The manual is unclear in which weapon mode you should be to deliver lysbomb (I tried PLAN, RR and ATTACK).

The manual states that lysbomb could be delivered in NAV or ANF, but NAV + unsafe does not produce any popup indications in game (ANF does).

Even though I am reading directly from the manual I have a really hard time even dropping them. I dont know what I am doing wrong.

I am in ANF, Attack mode, RAKT mach 0.9 at 150 meters and I see the blinking line and pull the trigger pushing upwards in 4G.

I have managed to get maybe three releases of 15 tries.

Exactly, I experienced the same too in NAV+unsafe.

Same issues here but I can't get the flashing distance line for release …

Literally built a demo mission for it - altitude is 150, speed .9 (AB2 to get there... ) and I've tried in both ANF and NAV.

Also tried PLAN & ATTK but the manual doesn't say anything. I know the sight switch has to be in ILUM.

Anyone figure this out?

LysBombs currently need a QFE setting of at least minus 100 mbar from original value in order to illuminate timely and satisfactorily.

Otherwise the leading 2 or 3 bombs will hit the ground while already illuminating but still not having their parachutes deployed.

I attacked a track where I got very good results:

Here is another one with 8 bombs:

It is not the QFE, it is the wrong release pattern (vertical tower instead of horizontal plane), that is the problem. This problem must be super-duper low on Heatblur's priority list because it exists since like forever and has been reported almost as long. It was probably an easier fix to put in NVG instead.

Gonna bump this up, LYSBOMB profile is still incorrect.

Bombs still fall vertically instead of horizontally.

Still the same and when released over the Sea there is no reflection on the water at all. 

Thank you all, tracked.

As for the water reflection, we need to see if this is us or DCS general issue. Do other illumination bombs reflect? I havent used any myself in a very long time... Thank you!

I just tested it with the MiG-21's illum bombs: It's a general DCS issue.

Last time I checked the same issue with water happens with helicopter search lights as well, the water just stays a black void.

Ok, thank you so much guys, your great reports really help tons! In that sense, if you want, it would be best to make it a general bug report with ED, unless it already exists, or add your findings to existing ones. Thank you!

*IMAGE*

 

There is now light/reflections on the water. Still the same pattern on the bombs though.

Uhhh, nice! Why the green colour though?

New algae bloom model

This still seems to be an issue

There is an page from the manual that widen76 have posted here -->

It shows a detailed info about were/when/how the flares should be in the air.

I noticed another bug with this.

The image above is for 4 illumination bombs for one store, we can only have 2 ingame now.

There is another page in the same document noted above that confirms this.

I don't read Swedish. Is this saying 4 lysbombs per station/pallet like the M71s?

I assume so, it say 1-8 bombs for just the inner or outer stations.

If you you would put lysbombs on all stations they still drop according to the image i posted earlier only dubble since it says that its the same for the inner or outer stations.

My translation of "Tillåtna lastalternativ" is "allowed load options".

If a translation is needed of the pages i could give it a try.

S7V = Inner left store

S7H = Inner right store

LB = Illumination bombs

Are these bugs marked somewhere?

I guess no one use them...

Maybe @Silhou can check
