High drag bomb ripple timing

[Diesel_Thunder]

Was practicing with ripple delivery of high drag Mk 82's which brought up a few questions. We (dual crew, me as RIO) had 14 Snake Eye's loaded, and were going to drop them all in one pass. I had the armament panel set up correctly; MECH fusing to N/T, ELEC fusing to INST, delivery quantity set to 14, Attack mode to Computer Pilot. I left the interval at it's default setting of 50 ms. Stations 3, 4, 5, and 6 enabled.

We came in around 500 feet, 400 kts. Once we got over the target my pilot held down the weapon release and initiated a slight pull up as the bombs came off. After the last one released, we then dove down low and in burner to egress out with countermeasures in trail. Pretty solid attack run, though the bomb spacing was really close together. Which brings up two questions.

1 - The Computer Pilot attack mode, which I've come to understand is sort of like CCIP in the more modern jets. In a ripple delivery, does the pipper indicate the middle of the spread like it does in the Viper and Hornet, or does it indicate where the first bomb will fall?

2 - The manual does not have a bombing table that show that if you are at X speed and want Y distance spacing on your bomb impacts, then set the interval timing to Z. I didn't see anything similar in Chucks Guide either. Is there any advise or tables available to set the release timing?

Yeah there is, in default kneeboard pages, it doesnt have title though

 

about question 1

IDK but i suspect its simple and old system, CCIP would count from first bomb

I have a couple of pages here: https://flyandwire.com/kneeboard-pack/

The idea was finding the closest setting to get the desired spacing (15ft or 60ft). I wrote a simple script that, starting from complete tables, fetched these values. Hope it helps.

Afair there was a high risk of blowing yourself up when setting ripple to less than 200ms with high drag bombs.

I would never have thought to look there, thank you for pointing that out!

Wow, that's a wealth of information for the backseater. Thank you for sharing that!
