MK82 profile CCRP 5MIL

[InteR]

Hi, I have noticed that when I choose or create a MK82 profile (CCRP), by default a CR 5MIL is set by default, and it visible in the HUD.

In the profile I can't find a way to remove this CR. I have checked the in the IFFCC TEST menu, the "CCIP Consent OPT" option is set OFF.

I don't understand this. How can I remove the CR 5 MIL?

Thanks.

The screenshot shows CCRP. The consent to release is a given in this delivery method and, naturally, can't be removed.

Can you confirm and possibly show with a screenshot that the consent to release is also shown in CCIP with CCIP CONSENT OPT set to OFF? Even better would be a short track showing the issue.

Hi Yurgon, 

I have managed to replicate it again. This happens when I create a new profile for MK82 bombs in CCRP mode.

I don't understand why it configures it in CR 5MIL mode without me touching the CR option in the IFFCC menu.

I am sorry, I don't know how create a track. But I only did a new profile for MK82 in CCRP mode.

Thanks you.

Maybe I didn't make myself clear before. CCRP always requires the pilot's consent to release, and in turn also requires a release constraint. For unguided bombs, this will always be 5 MIL, for guided bombs this will always be 3/9.

You might want to brush up on the CCIP and CCRP chapters in the manual.

For CCIP, by default there is no release constraint and the bomb is either pickled when the weapon release button is pressed, or it isn't. CCIP Consent to Release is only used when this is set in the IFFCC to offer pilots more flexibility, should they need it under specific circumstances.

With the edit to your first post, the answer should be self-explanatory by now. CCIP CR doesn't impact CCRP, simple as that. I guess the real question is: Why did you think it would?

It may help to understand, what CCIP CR is useful for.

If the pilot needs to acquire the target visually (does not know the exact location), but doesn't want to dive too low (risk of AAA or restricting terrain) CCIP CR allows to dive into, a valley surrounded by high mountains, for example and acquire the target in CCIP, put the pipper on top and then press and hold the pickle button. This gives CR symbology (Steering Line) and now the pilot can pull out of the dive (no longer seeing the target) and fly the TVV on the Steering Line as he would in CCRP and avoid the mountains or pulling up too hard (slowing down).

So as Yurgon explained above, CCIP CR is a separate mode from CCIP and CCRP.

CCRP only works with Consent to Release, whereas CCIP CR is a "specific submode" combining CCIP's visual target acquisition with switching to what is basically CCRP, on the fly.

No it doesn't. You are thinking about the F-16's dive toss. The A-10 can't do that. The CCIP solution assumes that the flight path marker stays frozen. You need to continue your dive until weapons release. It is not a dive toss mode. The CR is more for situation where you have a low mil depression because of the delivery you are doing and because of winds the solution is pushed out of the bottom of the HUD. You put the pipper on the target and you continue down the same wire until weapons release. It should only take an extra second or two for the solution. Times you'd see it is a low altitude level delivery of CBU or something with a low mil depression and winds force you to have to basically be over the top of the target, or a 30 HADB type delivery where the mill depression is like 300 mils and near the bottom of the HUD in a no wind condition.

The CCIP pipper is doing the trigonometry based on the jets current parameters. If you hit the pipper and then start your 4 G safe escape you are going to invalidate that solution and lob the bomb well long of the target.

What is depicted on page 376 and 377 in the A-10C II Manual, then?

To me post designate symbology looks pretty much exactly how the CCRP symbology looks, with the exact same cues?

Where did I go wrong? I assumed CR modes are to allow attacking a target below your nose, after acquisition in CCIP. And the 5 mil vs 3/9 mode is about the accuracy of the drop?

Didn't think about anything F-16, especially not "dive toss" with an A-10C

It has more similarities with the AV-8B's CCIP to AUTO conversion... which is not a dive toss mode, as well.

EDIT I read a little bit. From the A-10C II Manual (P. 375):

(...)"3/9 Release and 5 Mil Consent to Release (CR) Bombing Modes

Both the 3/9 and 5 Mil options use what is termed Consent to Release (CR). The only difference between the two is how accurately you must have the pipper pass through the solution cue to release the bomb. The advantage of using CR is that you may designate a target point and then pull-up and release the bomb in a non-diving attack. This gives you the option of wings-level bombing and toss bombing depending on the attitude of the aircraft at weapon release."(...)

Thanks you Yurgon and shagrat. I have understood all you have written above.
