[REPORTED] JDAM issues

I´m trying to hit several targets in one single pass (4 bombs, one each station), so I watched some videos and thought I had learned how to. Or something is bugged, or I am doing something wrong.

Let´s see:

1 - Turn on TGP, Master Arm, A/G, and select JDAM;

2 - After some minutes everything is on (TGP and JDAM is ready), so I start to set the things: EFUZ Inst, select all stations (QTY), PP mode selected (PP1), and fly to the OA;

3 - Find a Target, change PP to TOO, TDC depress, and return to PP mode. Ok, the coordinates are stored to the station linked to PP1.

4 - Remember I´m on PP mode! Press Step to change station (it changes), and automatically mode is change to TOO! First weird behavior!

5 - Press mode to PP, and my PP1 is already set in the new station with the old coordinates!!! Second weird behavior.

6 - Keep trying to set the other stations with the same result!

What I´m trying to do? Set all the bombs in PP1 mode (using TOO mode for each one), and release them all in one pass.

What´s the issue?

What´s the issue?

Behaviour has changed since the addition of the Viper, so previous guides and youtube videos don't apply.

IMHO it's best to wait until ED decide on the correct implementation for Hornet PP drops.

If you must try, this is supposed to work -

YMMV.

How it currently works:

Every station has its own master mode (PP or TOO) saved and submode (TOO1/TOO2 and PP1,2,3...) saved. So, you can setup each station to master mode and submode you want, and when you cycle through other stations back to it, it will display mode and submode just as you left it.

There is an exception though. If you have a target designated in the system (via HSI or via TGP, or whatever other mode), when you press step, next station will default to TOO1 automatically.

Method that works is:

1. Select efuse and qty.

2. Step through each station and set it to TOO

----------------------------

3. Designate target

4. Change to PP and then to TOO again

5. Undesignate target

6. Step to next station

----- Go to 3. and repeat the process for all stations

7. Step through each station and switch it to PP

8. Drop bombs.

thats exactly how it worked "before viper update".

+1. That‘s my approach to it as well. I still play around with them from time to time but only with single bomb on each station.

I don‘t get to fly so often these days and that makes it more difficult for me to break/change the muscle memory for JDAM employment once they implement further changes to the logic. So I refrain a bit from using them until we get more updates.

No, before the Viper update, if you set a Hornet station to PP, it stayed in that mode.

Currently, with a designated target i.e. via TGP, waypoint, etc., stepping to a station *automatically* puts it in TO mode and switching it to PP, updates the station's PP co-ordinates to the current SPI, rather than use it's current value.

Due to this, once PP1 / PP2 have been programmed, you *must* undesignate any target point.

You can then step though the stations and set them to PP. As there is no designated target point, stepping through the stations again they remain in PP mode and you can perform a multi-drop in one pass.

Previous Behaviour

Before the Viper update, after using the TGP to uploaded PP targets, you could leave it looking at the last target i.e. to monitor for threats during your ingress and for BDA on your egress.

If you do that now, the TGP's SPI will overwrite the existing PP points, as you step between bomb stations.

Me three.

There's too many other games to play at present for me to bug test JDAMs and learning procedures that may or may not be changed. I keep thinking I'll wait for the dynamic campaign and be done with it.........

I thought the recent update (11/01) had fixed this problem :"Corrected JDAM's drop sequence.".

Nope! The bug is still there!

So check these videos made BEFORE the viper update, and watch the procedure done. Try to replicate it, and later tell me why we could manage the bombs dropping perfectly, and now not!

Have you seen a single time in one of the videos, an UFC input? I really don´t understand your statement…...

His statement is that pre viper version was wrongly programmed. Current one as well.

I found out pre Viper that the most accurate way to always hit 4 targets with 4, or 8, JDAM’s in one pass was to assign each target to a waypoint and then input those using the TOO, WPDSG on the HSI, then PP, then step, TOO, WPDSG, PP, step, and continue until all stations were programmed. I entered data/precise first, though I don’t know if that mattered. So it sounds like that was incorrect too relative to the actual Hornet. Too bad, I enjoyed that method. So, I too am going to wait for the fix. Plenty of other things to do and learn.

Well I came here looking for answers and left even more confused than when I arrived.

I have used the technique described in this guide with success before.......

Using this technique on the latest version yields no dice, all the bombs hit the final object targeted.

If there is an intentional update to the method and a guide I would appreciate a link, thx.

i guess all he is saying is: The procedure is the SAME. but now, when you release your PP point, "If you do that now, the TGP's SPI will overwrite the existing PP points, as you step between bomb stations."

not sure i haven't flown the hornet since viper update.

There is guide in post 3. Keep in mind that method will eventually stop to work.

No, PP should only allow tgt data from UFC and Mission Editor

 

TOO will allow entry from TGP and other sensors, but if dropping multiple bombs, they will hit the same target.

Oh got it, that is a huge change then.

Can't get multiple JDAM on different targets with TGP

I've been following Chuck's guide exactly but every time I end up with all JDAMs hitting the last designated target instead of each hitting different ones.

What I'm doing:

- QTY select all stations with JDAM

- MSN - pick TOO

- TGP point designate - co-ordinates entered in TOO1

- switch to PP - co-ordinates transferred and saved in PP1

- STEP next station

- pick TOO (although usually it is by default after STEP)

- TGP new point designate - co-ordinates entered in TOO1

- switch to PP - new co-ordinates transferred and saved in PP1 for new station

etc.

but even though I watch to make sure every time I designate with the TGP the co-ordinates change, in the end all bombs just go for the last target. :doh:

Obviously doing something wrong but no idea what.

Currently borked, it is in the bugs section, go back to release , that still works perfect thankfully.

Oh pfew, thought I was going mad. Sorry for duplicate bug report then. I followed links in the bug thread to a workaround. Going to release isn't really an option for me, playing mostly MP and all my squadron is on Beta.
