Dive Toss dropping bombs very very very, really very off

[leonardo_c]

Used to work before the patch and I had no problems hitting targets consistently, now I'm completely unable to hit any target, following the guide according to

https://f4.manuals.heatblur.se/stores/air_to_ground/bombs/employment/accurate_modes.html

Track in attachment, adding also video.

Already tried a repair, the issue is consistent and 100% reproducible, starting from air and from cold start on apron.

Two potential issues:

1. Drag coefficient was still 0 in the bombing calculator.
2. You didn't fly the reticle bank indicators for release (they showed your wings banked right instead of staying level).

the bank was intentional to figure out what is happening, at that point it is way off and should have released waywayway earlier.

I also noticed the drag coefficient to 0,before the patch jester would set a number there.

Last I recall I had to re-input one of the entry fields for the coefficient to populate if I selected the weapon.

and you've put me in the right track, I decided to drop without opening the bombing panel first.

just select DT, lock target as usual and pickle, perfect hit.

The issue is in something done, or not done, or wrongly done, by that bombing panel.

 Set the reticle to 45 mills. Set A/G. Take your time. No hurry.  With that low pass you probably would have damaged yourself. No need to adjust parameters, 'Tell Jester' to do that.

That's also what I've been doing, at least with Mk81/82 slicks and high-angle dives. For anything else I use the calculator.

What's occurring seems to be your lack of dive angle input in the bombing computer which provides a drag coefficient of 0.00 to Jester which he latter inputs into the WRCS (as the drag coefficient is required for DT). In both cold and hot starts, it appears the WRCS' drag coefficient is set to 1.02 (which is roughly what Mk-82s are in typical DT weapon release conditions) by default which is why you're seeing hits without the bombing table.

What I typically do is put in a rough approximate dive angle and that is fine since the only bit required for DT is the drag coefficient. Hope that helps.

I remember that before the patch there was no requirement to specify any dive angle, also such requirement is not specified in the employment guide from heatblur so for me still something is not right in the bombing panel.

It was always required to input.

It just happens to be the case that, as DSplayer explained, the default settings roughly line up with a typical and reasonable DT attack profile. Which is why, if you fly such a standard attack profile, the default settings usually serve you well.

As soon as you fly any other profile, not inputting the right drag coefficient (which depends on *all* settings the bombing tool asks you to enter) will result in missing the target.

You can easily experiment by entering different values into the tool and observe by how strong the drag coefficient value changes. If it barely changes, you can see that this kind of profile would be very forgiving.

Why is it defaulting to 0.0 instead of 1.0, and why does the UI often fail to respond to mouse clicks? It usually takes me 10 or so clicks just to open the bomb selection menu, and if I want 0 degrees, I have to set it to a different value and then click it back to 0 again just to get the correct coef.

It is responsive for me. I am not sure I understand your questions of "why" though, its obviously just bugs that will be squashed away eventually when someone mentions them. There is no intention behind making suboptimal user experience, why would there.

Can you tell me how to use the Bl-755 in DT mode? I've never used this bomb because the F-4 has a lot of other bombs.) Today I read about it on the Internet and decided to try it. But, it's not in Juster's bomb calculator.

If you select CBU-87 you get reasonably close results for the BL-755.
