reported earlier CCIP of F18 is inaccurate for me

[FrostLaufeyson]

In my testing, the CCRP is very accurate, almost like magic. But I find that CCIP bombs are always less accurate, and their final hit point is always lower than my CCIP crosshair.

I have no problem with my GPS and AGR is on, but it just isn't accurate. This problem has been bothering me for a long time, is this a normal performance or a problem in the game?

My trk file shows several CCIP bomb drops, my operation may not be very standard, but you can definitely find that my drop point and bomb hit point are inconsistent.

I‘m posting to ask if anyone has the same situation as me.

The Hornet IRL is supposed to be capable of 1 MoA accuracy in CCIP bombing. That's approximately 5x more accurate than the F-14 when dropping dumb bombs, to the point that the Navy stopped tasking the Tomcat with dropping unguided weapons entirely. 

Right now the experience in DCS is the exact opposite, and it feels quite wrong.

Havn't watched your track yet but I also noticed that my bombs always dropped a bit short when using CCIP. Wasn't sure if it was just me being incompetent. Will try it on the weekend again.

Mine are falling short too most of the time. Don't have a trk and I'm not a good 'dumb-bomber' in any way but though I feel the same inaccuracy.

Aim high. We call it holdover with a rifle.

CCIP target point may be inaccurate, but I have had good success rippling 2 with 150 FT intervals.

[silverdevil]

CCIP in both hornet and viper, i place the aoa indicator a few hundred meters ahead of target (the aim high comment) while i am diving on the target.

You mean the flight path marker, a.k.a velocity vector, right?

I took a QUICK look at the track in Tacview: (this is the first drop)

 

Slant range (at drop) is 1.21 nm = 7352 feet... Impact is 62ft from the target. 1 MOA @ 7352 is about 735in = 61.25ft ... 

Unless, of course, I messed up somewhere! (Always possible!)

What is the width (in MOA) of stadia mark of the F-18 HUD?

One thing I'm doing as of late if to reduce the brightness of the HUD to get a better look at the targets...

I have done a bit of testing and found that the Hornet in CCIP drops consistently 200 ft short of where the pipper is in a 45-degree dive from about 20,000 ft. I ripple two at a 200-foot interval and the second bomb almost always hits exactly where the first one should.

Wait are you saying when you ripple 2 with 200ft spacing the second bomb hits where the aim point was? Because that's not 200ft short, its 100ft short.

That's what happens. My understanding is that the first bomb is supposed to hit where the aim point was, and the second bomb is supposed to hit 200 feet beyond that--is that wrong? FWIW, when I drop bombs in singles or pairs (with no interval), they also seem to hit about 200 ft short.

AFAIK the standard behaviour for aircraft is the aimpoint represents the pattern centroid. I don't have anything specific for hornet, but its certainly supposed to work that way in harrier

yes. sorry. i used wrong term.

This is how CCIP works for F18 in the game, so does CCRP

So according to you, the two bombs should have landed 100 feet on either side of the target. However, the problem with the CCIP crosshair actually caused your bomb to drift 100 feet, and finally the second bomb landed on the target.

I don't really understand these specific calculation, but even so. . The bomb will deflect these distances each time. So doesn't it just need to move the crosshair down a little to solve the problem?

OK, thanks (to you and Swiftwin9s) for clearing that up for me! But yeah, as you say, there's still a problem there.

[FrostLaufeyson]

If you have no other questions, I will report this as a bug next Monday

[Wiggo]

Has this been fixed yet? I have pretty much same kind of problems. What comes to ccip of gun (in A/G mode ofc) it seems to fly over the target.

[MTM]

Seems to be working fine for me. 

[BIGNEWY]

Hi all, 

we are ware of a POS/AINS issues and it is being worked on. 

thanks

With GPS it is meant to work currently then? I may just be bad, or misunderstand what's being said here, but I also noticed the point being off with AGR and GPS. What I typically do when bombing a tank, is to press the button when I'm past the tank about 2-3 tank lengths. And then I get pretty close. That way I can use a smaller spacing.

There is an option to UPDT the GPS which may cause a very minor shift in hud targeting. I’m not sure exactly how it works (I don’t use ccip very often). Perhaps try that as you get very close to the target location, just to see if it changes.

The UPDT option is used for correcting INS positional drift, analogous to the FIX options in the F-16 (only available if the position-keeping mode is not POS/AINS).

You’re probably right, but I *do* see the bomb fall line shift very slightly (I’m talking pixels here) after UPDT/ACCPT in gps mode.
