[WIP] New JDAM/IAM profile settings? But do they work?

[AvroLanc]

I've stumbled across new Profile Settings for JDAM and IAMs.

 

When you change settings, there's new options for 'Target' and 'Waypoint ID', along with Impact AZ and Angle. There's also a new HUD symbol.

 

The target settings are presumably used for pre-planned targets.

 

In my screen shot below I've entered Waypoint 6 as the target, which is accepted. This also generates a new HUD symbol. A small circle with a dot is placed at the location of WP6.

 

 

The problem/question is that the steering commands for the GBU-38 LAR are still towards the SPI, which is not WP6....

 

I would expect the LAR etc to jump to WP6 (Entered Target location), instead of the SPI in my case. This might not be implemented, but is there another step I'm missing? Is this a hint of further additional functionality to come?

The addition of the HUD symbol indicates maybe........hopefully.

WIP...

so this is planned to be implemented? that would be awesome

Yeah that’s low key great news!

You can have a close group of f.ex 4 targets, then use the TGP to make a MARK point on each target i.e MARK point A, B, C &D.

In the profile You can set the MARK point A as target.

Then You need to set the SPI on that target or just close to it, f.ex in the middleof that target group.

Then drop a single bomb and it will hit the target under the MARK point A.

 

Change the profile to the next MARK point f.ex B and reattack.

 

The above works fine for me.

 

I guess You can make serveral profiles, with each MARK point (A, B, C & D) and then select first profile, attack, select next profile, re-attack and so forth.

If Your quicj on the fingers You might be able to do this in a quick succession and thus hit serveral targets in one pass, if they are all close to the SPI.

 

Question is, if it is possible to give each bomb it´s own MARK point and then by dropping 4 bombs, hitting 4 targets in one attack run.

This would still require the SPI to be near all targets.

You can still do it w/o making profiles.

Just set Marpoints, set SPI to STPT (TMS aft long), make HUD SOI and using DMS up/down you're changing Markpoints hence SPIs. If you have UFC binded to some device you don't even have to make HUD SOI, just press STEER +.

It's quicker - don't have to copy and edit profiles.

That would be great, but AFAIK it doesn't worka like that at the moment.

Making different profiles would be useful once (if) terminal options get done. That way each bomb/target can get different attach azimuth and angle. Possible use.

[AvroLanc]

Just as an add on to this thread....

 

The JDAM terminal parameters do actually work in the A10. The Impact Azimuth is respected, the bomb will attempt a terminal maneuver to impact at the correct setting. There is a bit of a margin, often it will impact +-5 degrees either side...

 

I've not seen a major difference in Impact angle, but needs testing more. The GBU-54 release/standoff range is still really low. (Reported)

 

Even so, this is cool, and good news. Bodes well for implementation on Hornet and Viper.

That's a very nice surprise! Actually it's an undocumented feature, the manual doesn't say a word about this new options.

I thought this was implemented. I made four profiles JDAM1, JDAM2, JDAM3, JDAM4 each with a target waypoint MSNO01, MSNO02, MSNO03, MSNO04. I flew toward the waypoints and released, next profile, released, next profile, etc. They ended up going for my SPI.

 

Is this not in yet?

Yes, it's worked since the Warthog II was released. Your SPI has to be set to IFFCC for it to work, though.

edit: When I last tested impact azimuth and angle (many months ago), azimuth seemed to work, but it was hard to really be sure because impact angle didn't.

I should note that while it's not *usually* as useful as just using markpoints as your SPI, it does allow you to plan sequential drops of varying weapon types and targets with far fewer button presses, simply be re-ordering your DSMS profiles. Copy-pasta from a pair of posts I made on Casmo's Discord a few months back to follow:

Let's say your target area has two target structures that you're supposed to drop 31s on, which are steerpoints "TGT A" and "TGT B." You have a secondary target, a fuel depot, that you're to drop a 38 on, which is steerpoint "TGT C." The three targets are located with a mile of one another and reasonably lined up north-south, with the fuel depot being between the buildings. With your TGP, you spot a pair of BMPs, one south of TGT A, one north of TGT C, and a watchtower north of TGT B. All six targets are located within a mile and a half of one another. To hit everything in one pass, you'll want to drop, in order: GBU-54 on the first BMP, GBU-31 on TGT A, GBU-38 on TGT C, GBU-54 on the second BMP, GBU-31 on TGT B, and GBU-38 on the watchtower. (You're dropping the 54s on the BMPs because they're potentially mobile, and could therefore lase one if it starts rolling.) Using the tried and true method of swapping steerpoints with DMS up/down and weapons with DMS right/left, you could drop the appropriate weapons on the appropriate targets in a single pass... provided that you're extremely fast, memorize the target and weapon order, and you've either converted the three pre-planned targets to markpoints or the three markpointed TOO targets to steerpoints. Since the A-10C II module came out, though, you can tie GBU-31/38/54 profiles to a specific steerpoint or markpoint. Example: Create a new GBU-31 profile, title it TGT A, set its assigned steerpoint to TGT A. Rinse and repeat for the other weapons/targets, reorder them in the profile list so that your drop order is set, select the TGT A weapon profile with DMS right, make IFFCC SPI, "1, in from the south", fly towards the targets, "1, pickle times six," pickle, DMS right, pickle, DMS right, pickle, DMS right, pickle, DMS right, pickle, DMS right, pickle, and "1, out to the west."
 

It's definitely a niche alternative, but I find it useful for pre-planning attacks. It takes a bit more time to set up, but it reduces your workflow during the actual attack run. (Example: If you're attacking a site with 10+ markpoints, you can just pick the four that you want to attack in advance rather than potentially needing to juggle what you're actually targeting - you just set the drop order and start pickling.)

For that particular example, using markpoints, that would be (assuming markpoints were in order): DMS up, DMS right to GBU-54, pickle, DMS up, DMS left twice to GBU-31, pickle, DMS up, DMS right to GBU-38, pickle, DMS up, DMS right to GBU-54, pickle, DMS up, DMS left twice to GBU-31, pickle, DMS up, DMS right GBU-38, pickle. That's 18-20 button presses in a short period of time with a high potential for doing something wrong compared to 11 presses with no thought whatsoever during the actual attack run.
