How to drop new JDAMS

i noticed that i can't cycle through *all* of the bombs on my aircraft...

Lets say i have 6 gbu-31s. I can now cycle through 5 of them: Left wing, left forward fuselage, right forward fuselage, right rearward fuselage and right wing.

for some reason i cannot always cycle through all of the bombs on the fuselage

Yeah, i've seen this too occasionally where it'll steadfastly refuse to cycle through one selected station. Sometimes deselecting and reselecting the relevant pylon in the armament screen fixes it, but it is an irritating issue.

How far have you got with it so far?

- Have you set the target points up in the Mission Editor?

- Can you see those target points in the Smart Weapons page in the jet?

Once you've got the targets (missions) in a state that they show up in the jet it should just be putting it into CC MEM mode, use NEXT MSN (or NEXT SET if you have multiple sets defined) to step through them and MSN XFER to transfer the currently shown data to a bomb (then NXT STA to step to another bomb). Pages 499-500 in the latest manual revision (13.4.7.4. CC Memory Mode)

I've got it sorted now, thanks.  Grim Reapers video helped.

I have tried programming the JDAM's with the Air to ground radar and trasnfer 6 different targets to 6 different JDAM's.

The coordinates for all JDAMS differ, but when I release them, they all hit the last designated target on the Air to ground radar.

On the SMRT page Wep Mem is shown, so I assume that the coordinates are transfered to the JDAM's

 

 

Figured this out. We have to wait for the "Designate" text to disappear from the radar/tpod before transferring the coordinates to the bombs.

Yes but don´t forget to undesignat the radar or TGP (Boat switch aft) before releasing the JDAM's

Haven't had any issues with not undesignating before drops.

Yeah, i've not noticed any issues with TGP-designated targets by not un-designating. Not tried using them for purely radar-designated targets as yet though (which I believe from skimming other posts is the context this issue applies to more?)

I haven't tried TGP drops yet, only radar. There were two instances where I had a bomb miss, both in different ways:

- One GBU-38 out of six impacted a previously struck target

- One GBU31 out of four impacted some random piece of dirt in the general target area

But neither have been reproducible. The other day I did a GBU31x4 toss on an SA-2 sight and each bomb impacted their respective targets as expected.

It would be interesting to know a bit more about how the system works if you indeed do have to un-designate. I assumed when you pushed the Xfer button it just sent the spatial data of whatever was designated at that time to the weapon and that was the end of it.

I´m not sure, since I haven´t really experimented with it that much.

But I guess that a target designated with the AG Radar will override the position loaded into the JDAM, thus You need to undesignate the AG Radar target.

Regarding the TPOD, this might work a bit different depending on whether the TPOD CDES is boxed or not.

Theoretically designating a target with the TPOD and CDES unboxed, will only designate at the moment You press designate and keep that spot as the designated target point also if You start moving the TPOD around.

With CDES boxed in will continually designate the position where the TPOD is looking

Question is just if there is a need to undesignate the TPOD before dropping JDAM's with positions ,oaded into weapon memory.

Until now I have undesignated both AG radar and / or TPOD before dropping JDAM's with good result.

Never did that and see no reason why one should do it.

Once you loaded your data into the bomb you are free to slew the TPOD around and designate another bomb; did this quiet a few times already.

Same here. Never been an issue thus far. Mind you, I don't select CDES when i'm programming JDAMs from the TPOD (didn't see the point/need) so maybe that behaves differently if you do.

I tried and tried. It’s okay for mk s and gbu s but when it comes to jdams the pickle button just won’t release them. And I get a message 108-90 in the HUD. or similar. What does that mean. 

[Sarge55]

You may already doing this but you need to hold the release button for a couple of seconds. A quick push and release will not drop the bomb.

If the bombs are set to AUTO, you will only be able to drop them when "In Zone". In DIRECT you can drop them when "In Range".

Is there a way to directly target a smart weapon at coordinates like 33010 '24.01 "N 35056' 37.93"E ?

Input those coordinates into a waypoint, then make that waypoint a target waypoint or whatever it is called (like for example 1.A) and then you can transfer that to the JDAMs.

Hmm as far as I know in order to transfer Navigation Target Points these have to follow a special naming scheme like "M1.x". How do you create those outside the mission editor?

Go to the steerpoint page, enter a steerpoint number, and then enter that number again but with a "." and that's it. That will allow you to transfer that steerpoint to the JDAM.

I don't see how. There is no XFER <anything> button on the SMRT WPNS page.

Make sure you are in AG mode and that you selected the Target Steerpoint, then the XFER TP on the left side at the top should appear.

You didn't mention the TPOD at all until now. Cueing the TPOD to a SP, designate and XFER TPOD is not really what I was asking and it can't be done sitting on the ramp either.

I don't mean TPOD and I didn't mention TPOD. TP is not the same as TPOD...

Just tried it, and it doesn't show TP but something else, sorry for the confusion.

When I use the TPOD and designate a target I dont get the weapon release line in the HUD.. I am in A/G mode with Master arm on... Any ideas? I was sucessfully using JDAMs a few days ago so I must be missing a step or a switch...

• Designate target
• SMRT WPNS page - XFRTPOD - data appears
• NEXTSTA
• Repeat
• AG mode - fly to target - no release line

I have tried different altitudes/speeds etc but cant seem to work it out...

Only thing i can think of in addition to that; You have a Weapons Program set with those JDAMs in it?

The only program I set for all JDAMs is Auto - Step - N/T
