Is JDAM AutoLoft already implemented?


Recommended Posts

Hi!

 

I've found some confusing info cross-checking posts and YT videos... So far, I can see the symbology for the Auto Loft delivery working (except for missing pull-up cues). But when I try it, bombs are not released, regardless of me climbing with the set angle (15-30-45°), holding pickle button before the release mark crosses the FPM... If I switch to Manual, bombs release as always.

 

I have seen a couple videos where this mode seems to be working (one lofting, one from Wags on level flight), but I am not sure if I am missing something...

 

Thanks!!

The Loft Initiation cues are certainly not implemented yet. (Along with Launch Points, Dynamic In zone cues, proper pickle behavior etc)

 

When I've personally tried to do a 15 loft, the JDAM often didn't release and when it did, didn't guide at all properly. There seems to be serious issues with the IN ZONE calculation at the moment, even in level flight. This is true for A10C II as well.

 

On top of that the terminal parameters entry doesn't get reflected on the Dynamic In Zone trapezoid on the HSI. Still WIP I hope. It's safe to say that JDAM's in general need a lot of work, including additional features, to make them as useful as they should be.

Well, I have just made an additional test, so here are the results:

 

  • PP mode: Entered the coordinates, set Auto-loft to 30°
    • Approaching the target in NOE flight, then pull-up to 30°, 5nm from the target... bombs do not release
    • Level flight at 20k, wait for the release mark, with pickle held 5-10 seconds before the mark crosses FPM... bombs do not release
  • Changed to TOO, found the very same target with the TPOD, and designated it, keeping all other info (Auto-loft 30°), fly level and... bombs did release!!

Weird...

 

(edit: grammar)

I was wondering about launch points, since ED never mentioned those. Do you think it will be implemented?

JDAMs are kind of a mess. QTY doesn't work right either in AUTO. The only reliable way to use them is in MAN mode, no term parameters set, and heading to the target. This will almost always work. 

 

Yeah, JDAMs have taken a downgrade in recent updates. Terminal parameters are very unreliable, since the IN ZONE displayed is often not correct, espcially at the edges of the envolepe. Also the flight timers (TTI) are always in error now. I see impacts with often 12+ seconds still running on the timer. They used to be far better at various points last year, to the exact second at one point.

Well Wags made numerous references to Launch Points as a future feature way back when JDAMs were first introduced. (See his youtube videos and comments, as well as mini-updates)

Among the items Wag's referred to and not yet implemented:

 

  • Launch Points 
  • Separate Target symbols for each PP target on the HSI (with impact heading stick)
  • Dynamic IN ZONE zone that actually takes the term parameters into account
  • Pre-planned IZLAR indications on HSI (that can be decluttered using the HSI option)
  • Correct pickle behavior (at least 300ms delay when pickle, more for longer QTYs)
  • More fuse options - JPF (fancy delay fuse), DSU-33 (airburst fuse)
  • Loft initiation cues on HSI

All of these explicitly mentioned either inside a video or in comments. Hopefully coming soon, please don't forget ED. JDAMs missing lots of cool button mashing functionality. 

 

Edit:

I found a quote from a Wag's mini update 25th March 2019:

 

''Later, AUTO delivery and much more detailed attack information will be added like the Launch Acceptable Region (LAR), dynamic launch zones, terminal attack option, launch points, release zones, JPF, BIT/MUMI pages, and multiple attack zones will be available.''

 

(Not the only example)
