CCIP aiming with mk-82air

[latearrival]

Don't call them dumb bombs. It's not politically correct. Call them "unguided" bombs. Just because a bomb doesn't have a fancy GPS/Laser guided system, it doesn't mean it's dumb. They're actually smart if you give them a chance.

 

Quite right too Kenan. Directionally challenged bombs, then?

Accuracy Averse Munitions I think is the PC term

Well. Here is the thing.

 

Today, I decided to try the MK-82 AIR under different parameters. So, I load up a *uckful of MK-82 AIR, set a few static objects on the tiny tarmac of the airfield NE of Batumi, +17 klicks away, and to do more passes until I've exhausted my load (LOL).

 

So anyways, I came up with a very important fact at the end of it:

 

 

• AIR is for unresponsive targets, typically installations, parked soft-skinned unarmed, non-retaliatory targets.
  

 

• AIR is best used under CCIP. Forget using CCRP mode with them, because no matter what you do, you'll never shack the way slicks do.
  

 

• AIR is best used at a 1000 feet, no less.
  

 

• AIR DTOF for HD and LD convey some special relation. I don't know it, no body does, except real life A-10C jockeys, who are keepers of the gate to precision and equipment spiking.. We, n00bs, don't even match real life pilots. But it is not a crime to try it out, right?
  

So, here is the track. I should be reviewing it, with remarks about dropping altitude, dropping speed, dropping range to target, settings applied each pass (LDTOF, HDTOF, RT,UP,E_Velocity, Delay, and footprint in Ft.)

 

 

Somehow, this information will be helpful to some of us, and perhaps, wise men of the Hog, can corroborate it, or even add some useful remarks.

 

 

And an assumption of mine: Eject velocity ranges from -10 ft/sec to 35 ft/sec, right? So, you'll note that I mistook the velocity for the footprint and punched the IAS to ft/sec conversion in the footprint. However, I wish to understand how a plane going at 261+ kts, has such a low limit of velocity?

 

 

Unless the zero value is the aircraft speed, that is another issue. Care to explain, fellas?

[BlueRidgeDx]

Can't watch your track, but the eject velocity should be left at zero. It represents the velocity at which the weapon is pushed away from the bomb rack by the release system in the pylon. It is totally unrelated to airspeed, and should not be changed.

 

The LD and HD TOF values are there because an 82AIR can be released in either HI or LO drag configuration, based upon the fuzing selected by the pilot (N, T, N/T), assuming it was wired up that way by the weapons crew. The different values allow the pilot to preset the desired TOF for both/either configuration ahead of time.

[Tailgate]

Great information. The amount of detail you guys have with weapons delivery is awesome,. Now if I can just get the ripple intervals figured out. lol.

I just call them special bombs.

Its easy to use mk-82AIR with CCIP, just change the fusing to 'Nose' and be sure to set a nose fuse setting in the inventory page on the DSMS.

That defeats the purpose of the Air and basically uses the Mk82-Air as a plain mk-82 with no drag parachute lol why not juse use mk-82's then. Good idea though if you don't like the air feature.

[BlueRidgeDx]

Your sarcasm detector is inop. ;)

A. Release Options

B. Of the default payloads you can select from the ground crew 2 of em are pretty similar, but one has 6x Mk-82s and no jammer pod, and the other has an identical payload but with 6x Mk-82AIRs and a jammerpod. I like having a jammer pod, and I hate the payloads that haven't got em onboard, thus I use the 82Airs in slick mode.

Thanks for the info BRDx. But shouldn't setting it to +35 ft/sec make the DRC appear at a much earlier range? And the MRS appears only with the CCIP which makes it more accurate at least in centering the nose of the aircraft with the target aligned.

 

I meant to ask you; what HUD object should be used to perfectly align the aircraft with the target? is it the PBIL, ASL, the HUD SPI indicator boresighted and then slewed down only on a stable autopilot path , or is it the cross + in the center of the HUD denoting the GUN long axis with the aircraft nose? (not the actual GUN aiming reticle, but the smallest cross atop the HUD)

 

Reason is, if you watched my track, I'm struggling to get the TTRN to be flush with the PBIL, the ASL, and the target.

 

Speaking about autopilot, I notice that when I R/L trim under ALT/HDG HOLD (middle switch postion), the aircraft wants to return to the heading when I first engage the A/P (meaning no fine heading adjustments without reversion to default heading) and this means subsequent loss of straight run on target. Should I use the ALT hold setting instead? (which is rougher by the way)

 

And the relation between LD HD TOF: When the bomb is first released, pending ballute deployment, the LD TOF governs free-fall time (X1), and HD TOF governs the high drag time (X2), both of which (X1+X2) contribute to total TOF displayed on the HUD, right? Or is it the setting of the fuze that picks one of them for a time to impact?

 

Thank you in advance.

No, the DRC is affected only by the DTOF. Also, the nominal Eject Velocity for each weapon already resides in the IFFCC. By entering a value in Eject Velocity, you're adding/subtracting a correction to/from the nominal value. Don't touch it, it won't help.

 

And the MRS appears only with the CCIP which makes it more accurate at least in centering the nose of the aircraft with the target aligned.

 

The MRS is available in CCRP as well.

(not the actual GUN aiming reticle, but the smallest cross atop the HUD)

 

If you're making a CCIP attack, all you need to do is:

 

1) Set the desired dive angle with the TVV.

2) Make lateral corrections as necessary to put the PBIL on the target.

3) Allow the Pipper to track upwards along the PBIL toward the target.

4) Pickle when the Pipper is on the target.

5) Don't hit the ground.

 

If you're making a CCIP Consent Release attack:

 

1) Set the the desired dive angle with the TVV.

2) Make lateral corrections to place the dashed reticle and pipper on the target.

3) Press and HOLD the pickle button.

4) Make lateral corrections to place the PBIL on the Solution Cue

5) Either maintain the dive angle, or make a gentle pull to "toss" the weapon.

6) The bomb(s) will come off as the CAP flies through the Pipper.

7) Don't hit the ground

 

If you're making a CCRP attack:

 

1) Set the the desired dive angle with the TVV.

2) Make lateral corrections to align the PBRL with the ASL. If the PBRL and ASL aren't aligned, that's ok, just roll to place the PBRL on the CCRP Aim Point (CAP) and pull slightly.

3) Press and HOLD the pickle button.

4) The bomb(s) will come off as the CAP flies through the Pipper.

5) Don't hit the ground

 

Reason is, if you watched my track, I'm struggling to get the TTRN to be flush with the PBIL, the ASL, and the target.

 

I'm unable to get into the sim today, so I didn't see your track. But don't worry about trying to align the TTRN with anything...it has nothing to do with aiming.

 

Speaking about autopilot, I notice that when I R/L trim under ALT/HDG HOLD (middle switch postion), the aircraft wants to return to the heading when I first engage the A/P (meaning no fine heading adjustments without reversion to default heading) and this means subsequent loss of straight run on target. Should I use the ALT hold setting instead? (which is rougher by the way)

 

Yep. You can't change the reference heading that the LAAP tries to maintain. In fact, if you trim, it should disengage altogether (known bug).

 

Regardless, you shouldn't be on autopilot while making a weapon delivery. Hand fly it.

 

And the relation between LD HD TOF: When the bomb is first released, pending ballute deployment, the LD TOF governs free-fall time (X1), and HD TOF governs the high drag time (X2), both of which (X1+X2) contribute to total TOF displayed on the HUD, right? Or is it the setting of the fuze that picks one of them for a time to impact?

 

The IFFCC uses either the LD or the HD TOF, depending on the DSMS configuration (FIXEDHI, FIXEDLO, PILOPT, etc), and DSMS profile fuze settings (N, T, N/T).

 

It's one or the other, not both.

 

Thank you in advance.

Thank you for such a wealth of information and bearing with all of us. I will practice using all your remarks.

 

Kind regards,
