Spacing out Durandals
-
What was your altitude on delivery, Frederf?

Well perhaps a confusion of wording but that point in the center of the CCIP pipper is where that first bomb will impact.
Start of the runway. Otherwise if you did your first pickle at mid runway when you have already exhausted roughly 3350 feet of runway already thus only leaving 3350 before you are into overrun. If you set exactly 600 on spacing that would have your 7th durandal lucky if it hits the overrun and 8-12 pounding dirt.
Apparently, this is no longer correct… unless I have a wrong setting somewhere.
I did a test, 12 BLU-107 @ 610’ CCIP. I put the pipper in the middle of the runway length and the bombs landed before and after the pipper with the center of the pattern where the pipper was.
Just did a similar test. 12 BLU-107s, 630ft spacing, CCIP. I pickle when the pipper is at the runway threshold and when I fly back for a BDA, I drop bombs BEFORE the runway threshold and it looks like it was trying to put my pipper as the center of the spread.

In 4.32, CCIP pipper was the beginning of the ripple. This has been fixed some time ago …
4.33 UP12- RC1 Changelog:
Fix CCIP pipper position to represent middle way of the bomb train when ripple is used. Note that for large ripple intervals this will not work exactly as expected. -
What do you guys do about release angle on a level, low level CCIP drop like this?
-
Release angle is not an issue. I think it’s just there for if you do a loft release.

Correct.

Ripple interval is not really suited to drop bombs along a long runway, it mostly is used to bracket a target and make sure that if the bomb train falls a bit short or a bit long, the intended target still get hit.

Thanks for confirming that guys. So manual-pickle is now the norm for a runway attack? Feels so weird having to space it out manually after having that “feature” before.
Still ended with mission success though!
-
You need to keep the pickle depressed all the way anyway, so between keeping it depressed and depressing it at regular interval, the difference isnt that great
-
Correct.
Thanks, I had this completely wrong. I always set my release angle for every type of drop, but is it only for lofting? That’s going to save me some work lol. Lots to learn
Anyway, I flew Ice’s wing on this mission and thanks to the advice here we did well. Photographic evidence as seen from one of the escorts on the mission

When we were planning the mission we talked about whether the CCIP designated spot started the string or marked the middle. Thanks to all for clearing it up, and in time for the mission. I had the fat one and even knowing how it would work I still put one through the threshold.

Well ironically now a days and with BMS directly into consideration how it handles runways the best way to attack those would be with JDAMs with penetrating warheads (GBU31(v)3/B) with precision steerpoints at the different runway bits. Depending on the runway the 3 or 4 precision steerpoints are all that is required to completely take out a runway as far as BMS is concerned. It also has the added bonus of allowing a completely stand off/ranged attack.

Just like it was said above release angle only has an effect if you do a CCRP loft delivery. If you do a level CCRP delivery it has no effect at all.

See the Icarus pictures just don’t make sense to me. The bombing pattern is showing all the way back to the ends of the runway but at a pickle spot right in the middle of the runway you have already PAST the initial bombing impact points. How are the bombs flying BACKWARDS to make patterns like that?
-
It’s not really flying backwards, more like he’s releasing from a higher altitude. I doubt you can get that result from less than 1,000 ft AGL.

Released at 1500 feet AGL at 500 kts in this picture.
500 feet needs to be manual. 12 bombs at 800 feet spacing requires at least 1500 feet. 6 bombs you can go much lower.
When you pickle the center of the runway your jet is not even over the threshold. They start coming off immediately and start dropping on the front of the runway.

Ah yes there was the assumption of a low pass not 1500 feet AGL.
