Bambr Posted November 6, 2015 Posted November 6, 2015 (edited) SU-25T has the bug with lazer mark on a target. The mark isn't placed on the same positions to target. Here are 2 screenshots where you can compare HUD and Shkval pictures. So the problem is HUD at this angle. If you put a plane nose down a few angles then HUD mark will be placed correctly (right on the target).

Esac_mirmidon Posted November 7, 2015 Posted November 7, 2015 When the point selected is below the HUD bottom the CCIP can´t go down. You must move your nose down to let the CCIP adjust to the true position. The HUD has a bottom limit to represent CCIP simbology. " You must think in russian.."

There is a space down of laser mark on these screenshots. Check this out yourself. Actually I've wrote this for SU-25A because it's critical bug for 25A when you aim laser guided missiles or aim unguided weapons below HUD's center. But it's a bit hard to see on screens and I've guessed to show the bug on SU-25T where you can easly compare HUD and Shkval pictures. The bug exists for both SU-25s and first appeared with new 6DOF cockpit.

Bambr Posted November 7, 2015 Author Posted November 7, 2015 OK, let me show this bug on SU-25A. The first screenshot shows laser mark which was placed on a target without moving it from initial position. As you can see the mark is placed just right on the target. Now lets look at second screenshot. Here I've moved down HUD glass and put my plane nose up a bit to see the target on the HUD. And as you can see laser mark is placed in the wrong position, much higher of the target. Now you see? I think it's a very important bug and should be fixed as soon as possible.

pepin1234 Posted November 7, 2015 Posted November 7, 2015 The Su-25T Hud is not an accurate source for aiming correction at certain distance. You should trust the ballistic calculation only when you are in the effective laser range. In the case of the Su-25T is 10km and in the case of Su-25A is 7km. The Hud is a representation only Anyway you should make some pipper movement closer to the target in order to correct the laser point impact always you get into the laser range effective calculation. Like that you get the best Hud response representation. [sIGPIC][/sIGPIC]

Like that you get the best Hud response representation. You did't understand the problem. Laser mark position depends on angle of view, angle of plane nose. So when you put the nose up the mark moves up and when you put the nose down then the mark moves down on a target. This means if you want to place laser mark right on a target you shoud do it when laser mark isn't lower it's initial position. More you put plane nose up more laser mark places in incorrect position. Intel Core i3-530 2,93 ГГц, NVIDIA GTX660, Corsair XMS3 DDR-III DIMM 8 Gb KIT 4*2Gb, LCD 1920x1080
Esac_mirmidon Posted November 7, 2015 Posted November 7, 2015 Maybe a movement limit of the laser designator stabilizator? Maybe the stabilization system has a mechanical limit moving down so you cant move noseup to a certain degree. " You must think in russian.."

When we had old SU-25s there wasn't that problem. And as I've said before you don't need move plane nose too much to see that laser mark leaves target position. Better one time to try this then many times to talk about it. Intel Core i3-530 2,93 ГГц, NVIDIA GTX660, Corsair XMS3 DDR-III DIMM 8 Gb KIT 4*2Gb, LCD 1920x1080

Esac_mirmidon Posted November 7, 2015 Posted November 7, 2015 So it´s not a 6DOF bug, it´s a "bug" related to the plane movement and the laser mark. " You must think in russian.."

mpdugas Posted February 2, 2016 Posted February 2, 2016 So it´s not a 6DOF bug, it´s a "bug" related to the plane movement and the laser mark. If I understand the thread correctly, and I've viewed the demonstration mission, it appears that it is a tracking discrepancy that was first seen when the 6DOF SU-25 cockpit was introduced, and not apparent in the older SU-25 cockpit (i.e. non-6DOF cockpit). Is that what you mean, OP?
Bambr Posted February 18, 2016 Author Posted February 18, 2016 Right. When you pull down the plane the lazer mark "shows" to you a lie. Thx to my mad skills in drawing you can see what I'm talking about. Intel Core i3-530 2,93 ГГц, NVIDIA GTX660, Corsair XMS3 DDR-III DIMM 8 Gb KIT 4*2Gb, LCD 1920x1080
