CBU HoF

[112th_Rossi]

I was flying a mission last night where I wanted to fly in fairly low (around 800 ft) over the target and drop a CBU (I forget the variant). I wanted the CBU to disperse at around 300 ft to create quite a localised area of effect. But I couldnt workout how to change the HoF function from 500ft. How do I do this? I hit the chg set button but can't see how to change HoF?

 

Thanks!

You need to set it from the inventory page, not the weapon profile page. The HoF is set on the bomb itself while on the ground and can't (in real life) be changed in-flight. Again in real life, the inventory page settings are just set to match whatever was configured on the bomb itself (so the weapons system knows what it's going to do). In the sim changing the setting on the inventory page magically changes the bomb to match, so you can disregard pesky limitations of real life if you wish.

Thanks! Hmm, do I take the realistic route? :D

800ft is too low to be employing CBUs. MK-82AIRs are the only non forward firing weapons you should be using that low. ;)

Navigate to your Inventory page and select CBU-87. Then use OSB17 to set the RPM to preset 1 (0 RPM) and OSB18 to set HOF to preset A (300ft). Thereafter load the info and you're good to go.

 

Just a matter of pressing the OSB's to select your preset.

At only 800 feet, a CBU-87 wouldn't generate enough spin to spread the bomblets out, and 300 feet is hardly enough to help. While it's not really modeled in the sim, in reality they'd all land in a big exploding heap.

big exploding heap.

 

That'll do :D

 

I was out of Mavericks and I was only going to use guns as a last resort. Lots of Manpads and IR SAMS in the target area. I just wanted to do as much damage as I could and get out using the terrain to mask my egress. I thought a CBU would do a fair amount of damage, especially since I wanted to destroy multiple static soft skinned targets.

Hey Rossi,you may want to set the HOF above 1500 ft or greater the pattern that they release at is larger and covers a greater area at a higher alt. Also if there are manpads in the area you don't want to get to low cus thats there killing range low flying aircarft are there bread and butter.:pilotfly:

300 ft HOF is pretty effective when you're dropping '87s on a tank, provided you're accurate enough for the "exploding heap" to actually hit the tank. It's certainly not the most efficient way to kill armor but if your only remaining weapons are a couple of CBU-87s and your target is a T-80, then at least you get to go home and put another hash mark next to the tank painted on your fuselage.

[Frostiken]

To be fair, life would be pretty damn unpleasant inside a tank that just had 200 grenades land on it.

 

Actually, I honestly don't even think dropping a CBU-87 at that altitude would even do anything - the bomblets have to experience 6G of decelerating force to arm themselves, and I don't even think there's enough fall height before it opens to get it up to much more than 120 mph or so. By the time it opens, they spread out, and they deploy their drag chutes, I think they'd hit the ground and dud.

Also: When the dispensers open at 300' ft AGL with a RPM setting of 400-500, the BLU-97s will decimate an area larger than 20,000 square ft.

Just to be sure -> There is no way to define the HoF before you enter the mission?! Does the mission designer have an influence on this setting? In this case, we could talk about realism and sticking to the setting. Otherwise, I'm afraid we do have to take this not-so-realistic way of changing the HoF via the INV.

That is a valid point! Not to mention that the option is there, even in sim mode, for a reason. Some elements of realism have to be fudged for playability, IMHO.

[112th_Rossi]

We need something like the Tornados JP233 :D

You can use the 'prepare mission' option to preset various avionics settings, although for the DSMS this tends to cause issues if the player chooses a different loadout. Also I think it only works in SP mode.

Yes, but you can simulate reality by only changing them when you're parked on the ramp, i.e. at mission start or after re-arming. Changing it in the air is the massive departure from reality.

Indeed. That would Be an option!

[Divide Et Impera]

The prepare mission options ? Wharf is it located ? I've never heard about it

In the mission editor, check the menus at the top. ;)
