Level bombing, my rule of thumb which works fine is 500' at 500 kts. Obviously terrain will dictate your approach.

Hello to all.

As I 've read somewhere in the forum that the programmers need us in order to help us, I want to tell this: when I start the AV8B on the Tarawa with A/G ordnance such as GBU 12, a part of the AGL line (CCRP bombing) that doesn't work fine like in the A10C, if the flight path is correct, the gbu's work fine and they hit the targets. On the countrary, when I start the same mission with the same weather conditions and at the same time with an air to air configuration and after I land on the Tarawa asking to the ground crew an A/G configuration that inlcludes GBU 12, after the gbu's don't work. I tried to fly in the best way like when I start with A/G configuration ( Ialways use CCRP - Auto mode) but there is no way to hit the target(s). It seems that the gbu's don't see the laser and, as a conseguence, they fall down like dump bombs... Another thing....the Tarawa ship. It's able to take many hits from Kormoran and As20 antiship missiles without any result but at the same time the CiWS phalanx dont' shot to the incoming missiles. The ship seems "dead"... no effect from the missiles but also no reaction ..Did aAnyone noticed this or I am alone to have realized theese things? thanks for the support .... Bye Fabio

How close to the target should the velocity vector be? For a while I was getting solid CCIP solutions without even trying, and now I can't seem to get a solid solution any more.

It is also depending on speed. If you go too fast it may cause problems.

In general the CCIP is calculated by the ARBS and this takes a couple seconds. So if you move the plane too much the ARBS needs to recalculate the solution.

So if the cross is solid it has a precise calculated solution, if it is dashed the solution is more an estimate.

[Nealius]

I'm probably too fast, with my aim-off point too far away from the target.

I'm probably too fast, with my aim-off point too far away from the target.

Most important is to keep wings level and let the plane fly the cross over the target. If your angle is correct, you can place the fall line over the target, with the Velocity Vector on or near the aim-off point and the rest happens more or less automatically.

Key is t the roll in. If you end up with bad parameters, abort and run in again.

 

It isn't as easy, as it is to write it down.

You need to train the visual cues and a decent estimate if the distance to the target...

With BDU33s, at least, that doesn't seem to work. VV at 30°, Target at around 35° in the HUD, wings level, maintain 1G, fly the cross through the target, the cross never becomes solid. I pickle anyway, with bombs typically landing long (which I believe means excess speed). I'm going around 430-450KTAS at release.

[DJSean]

Sorry for the silly question, but where can we find development updates about the harrier?

 

Would be good to know what's currently being worked on and planned for the next patch.

Hmm, I didn't have much time to test this, but in a quick run in on the targets in the Instant Action mission with dumb bombs (Mk-82) it worked. No designation, simple eyeball Mk I attack from 12k feet, dive angle 15-20°, speed below 500kts. Stabilized between 8.000 and 7.000 ft with a slight but constant pull on the stick, solid cross after 2-3 seconds and could have pickled at about 5.000, if had not forgotten to arm the f...ing "Master Arm", again! ;)

 

If I have time I'll try to look up the speed (IIRC it was in the NATOPS Tac manual) and test with steeper angles and designation etc.

 

At a glance it looks like it works, already.

[al531246]

Steady parameters for a couple seconds, for the ARBS to calculate... No time to look up the exact parameters in the NATOPS manual, but I'm sure they are in there.

The key is to fly a proper bomb triangle/approach and put the nose/velocity vector behind(!) the target and let the plane fly the crosshairs through the target after leveling out, instead of trying to make last seconds adjustments... Easier said than done, I know. ;)

Lads, this is not an error you can fix. The CCIP bombing on the AV-8B is programmed incorrectly. The dashed cross IRL signifies that the piper is not the ACTUAL impact point. The CCIP piper / cross cannot leave the HUD FOV in the AV-8B IRL so when the impact point is off the screen it displays a dashed cross to denote it.

 

The dashed cross for 'inaccurate release' or whatever it's supposed to be is bollocks. It is not a function that exists.

 

Also IRL the DMT must be slewed to the area you're going to bomb say approx within 50ft or so of the target, you can't just select bombs and start bombing. You must give the computer something to range from. I don't believe this has been programmed in yet tho.

Partly yes, partly no. According to the NATOPS Tactical manual, chapter 2. it is explained in detail.

First the dashed cross, as you pointed out indicates a release point outside the HUD, at least IRL.

We miss the reflected CCIP as far as I am aware and it is strange with the impact point calculated short, as in the "angle cannot be exactly calculated as the area the aimpoint is looking at is outside the HUD (or more precise too far away from the flight path left or right will also give you a bad solution)" the bombs drop long and not short.

 

So I would expect if you pickle with a dashed cross the bomb should fall short and not long, so there likely is a bug.

Also the drop should be inhibited as long as the reflected CCIP bar is shown, so you shouldn't be able to drop, anyway.

 

Now the ARBS seems to be a very smart system. It uses either a GPS, a Barometric height, or RadarAlt to determine the height and calculates a CCIP (Continuously Computed Impact Point) and that is absolutely independent from a designation on the ground. A designation can enhance the accuracy, but the angle in ARBS is what enables the calculation of a bomb triangle.

This works pretty well unless your altitude above ground varies drastically from the target elevation.

You can see the current method of height calculation by the GCIP, BCIP or RCIP displayed in the HUD (I can at least confirm RCIP - Radaraltimeter is showing in the HUD in DCS).

If you fly good parameters it at least shows a solid cross as expected, and my drops where within acceptable range.

 

As this whole module is still early access and WIP, I would not bet on everything is 100% exact, already.

Unless Razbam gives us some details that is.

 

For now I try to get to grips with the real life procedures and studying the A1-AV-8BB-TAC-000.

...and I found the limitation. It is on the Mk-82 bomb, it says in the TAC-050 under weapons limitations for the Mk-82 something about 550 kts A/S, though the typical deliveries use 450 kts, 500 kts or 550 kts profiles.

So I am not sure this is relevant at all in our typical attack profile, as 585 kts or 0.98 Mach or more starts giving you trouble with the airframe anyway. :dunno:

[AcroGimp]

I picked up the Night Attack AV-8B as a tide-me-over until the Hornet releases and wow, what a complex beast.

 

Just starting on basic indoctrination right now, day/VFR unarmed fam flights but so looking forward to learning sensors and weapons, really a cool little jet.

Hello to all.

I have a question and maybe someone of you could help me. I am not able to get a valid lock on moving target with the litening in the AV8B. It works only with static objects. And with theese targets I can use Mav and GBU's. But when I click the button AR/PT only Area works or instead the button INR. But all theese 2 are not able to lock a moving target. Maybe because the litening is stil a WIP or I am not able and I do something wrong? Could you kindly help me ? Thanks .

[Pikey]

Currently a known bug that is fixed internally or close to.

Workaround is to hotstart your Harrier.

Thank you very much. I've understood. Actually my problem was that I remembered that al teast one time I was able to lock moving targets but when I tried yesterday I was not able and this is because I like to start the plane (the chopper...everything) from the cold....and that's the problem I think. I suppose it's a bug...you cannot lock moving targets when you start the plane from the cold..I hope that Razbam will solve also this... and soon....because now the module is out since last november and we are in march... bye

Hi I have a question regarding the Harrier and thought this might be the best place to ask.

Is it likely we'll see some more ordinance for the Harrier. I read it can use Harm missile and AIM-120? But can't see in the weapon load out screen.

[Einherjer]

AIM-120 only for the AV8B II+ , not for the night attack we have right now

[Fabion66]

Actually they don't give us nor what they promised in the advertisment...like AGM 65 E (laser Mav) and GBU 38 GBU 54 jdam...and also a well working litening...where it's possible to choose point tracking also when you start the plane from the cold....it would be enought if they'd give us what there is written in the web site substantially... now we are in april... :noexpression:

We are in early access...

So ofc the aircraft is not feature complete.

Wait and see what its like when it reaches full release and if things are still missing then there would be reason to complain.

 

Before buying a early access product always take into account the fact that it is work in progress and there will be a long time untill all the features are implemented into the aircraft.

Why should they... they never said it’s included to the early access produced. But they said the early access isn’t feature complete , please come back after release.
