Yes it moves but it does not change the fact that the distance between 1st bomb and the last one does not match the distance in the settings.


And yes the bombs are dropped at 1G load with a dive angle less than 10 degrees.


You can download and watch the track.

Did a quick test myself - see attachment.

That's a very good illustration. Thanks!

I was testing this out today as well and can confirm the interval of dropped bombs is far less than the one selected.

Didnt do any accurate measurements, but I found that the Mk 82 and Mk 82 snake eyes, use the interval setting differently?
With the Mk82's, it seemed like a 1st bomb to last bomb interval. So if I set that to 600, first bombs hits where I have the pipper, and last bomb aprox 600 feet later.
With the Snake eyes however, it was the the distance between each bomb (did use the Ret for drag setting). And the snake eyes came of the rack a little inaccurate, so sometimes (I was dropping 4) 3 and 4 had a lot less distance between each other.
I used unlimited ammo, and made many runs, with various intervals.

With the Mk 82's Id dive in from around 12K feet and a 30-40 degree dive angle.
With the SE's I would be level at around 500 ft, and 450 kts.
In both cases holding it steady, and just let the pipper walk over the target.

Edit: I should mention, this was on the X-field south of Kobuleti.

Is it possible that elevation of the target, or rather, the elevation above the target of the a/c is missing from the equation? It seems to me that the computer would need to know that in order to properly determine when to release the bombs.

No idea, just added to my above post, that these tests were done at the X-field south of Kobuleti, so all quite level.

It is usual to speak of time between release as "interval" and distance between impact as "spacing." That is one convention of these words, intervals of time and spacing of distance. Of course it is possible to talk of intervals of distance and maybe F/A-18 language is this way. Manual bombing profile is almost certainly in milliseconds while computed bombing is in feet. Be careful to report if your mode is manual or auto.

First a check if it is possible "200" is 200 milliseconds and not 200 feet. Three hundred knots is about 500 fps. Five bombs is four intervals, at 800ms total. 800ms at 500 fps is 400' total bomb stick length. Was your bomb stick length about 400 feet? Does bomb pattern get longer and shorter if release speed is higher and lower?

We can also calculate expectation. For five bombs at 200' we expect 800' total release path. Perhaps we find our true speed at release is 342 knots. This is 577 fps. The last bomb should release 1,386 milliseconds after the first. By replaying the track and setting time acceleration to 1/32x the time interval can be measured with a stopwatch. It should be 44.4 seconds. This gives an accuracy of 16ms (9 feet) if our stopwatch is accurate to 0.5s.

@Frederf: Good points here. Real pilots or the developers can now clarify whether it is time interval, release interval or impact spacing what we are entering there for the bomb release. This topic is not yet labeled as a bug or not so I am still waiting their response.



I still don't think it could be time interval because they wouldn't pass on the impact spacing calculations to the pilot while it can be done easily by on-board computers.

In AUTO/FD/CCIP the setting is impact spacing. In MAN its in millisecends time interval.
