ABRIS Map scale

[Bucic]

In civilized systems :P the map scale is given in relation to major display dimensions e.g. display height is 100 km. ABRIS guys did it "better". Their scale is related to 1 centimeter. They obviously didn't think of that ABRIS will be simulated one day and that it will be hard to determine how much is 1 cm in a simulation.

 

Imagine even real pilot frustration if ABRIS had a bigger display. "Wai, wait... My scale is 1 cm : 12.5 km. So what's the distance from my position mark to the datalink point about 17 centimeters up? ... It's... one hundred... ahm... two hundred twenty... :joystick: fourty ... damn it! ... :wallbash: ".

 

 

So my question is, wait for it, what are ABRIS display diamensions? :lol:

In the ABRIS / Map-submode is a ruler, called "Estimated Range and Bearing Line". This tool in combination with the "Marker" measures every distance (minimum 10 meter) on the ABRiS-map. There is no need for how is the dimension of the the ABRIS-screen.

[Bucic]

Believe me, If a certain display has no qucik reference scale then it's crippled in terms of usability.

I swore that the screen dimensions were in the manual some where. It would be a relatively easy test to use the ERBL tool and make a measurement of how much distance is represented by the screen at a certain scale and then using the conversion scale backward. Knowing range a fractions of the total screen dimension is absolutely a real Ka-50 pilot would know offhand.

 

Very good question, in fact rep for Bucic.

 

Does anyone know the manufacturer of the ABRIS AMMS and/or any names of its civilian counterpart?

[igormk]

I’m also almost sure that I saw or heard ABRIS dimensions somewhere. I’m not sure was it in the manual or maybe in some of Producer’s Notes videos.

 

Still as Frederf suggested we can use ERBL to measure it and we can double-check it with scaling it to diameters of Exhaust gas temperature indicator or Dual engine RPM indicator which I can find if you want.

 

S!

Check the PDF.

Thanks!

...

Some bad fate upon us. They provided only diagonal:megalol:

 

Edit:

OK, 150 x 200 mm +/- 1 mm.

 

Vhalha :D

 

It would be good to have even few dots on the edges of ABRIS display...

Make a cockpit mod ;)

[Bucic]

Can you point me to the texture. I'm making the scales ATM. 10 x 20 mm for height and 7,5 x 20 mm for width, not aligned to the display corner. Or aligned... :)

[Frederf]

Well if the pixels are square (and not rectanglular) then a 640x480 screen is 800px on the diagonal. 10.5" is 26.67cm.

 

The screen would be 21.336cm by 16.002cm or 213mm x 160mm in a reasonable format and rounded.

[Bucic]

ABRIS pixels cannot be square. It would be too simple :P

[Frogfoot1606687865]

Well a quick test, set the scale to 1:1 (1 cm = 1km) then use the marker/measure tool to measure the distance to the left edge = 7.8km. Then use the same tool to measure the distance to the top edge = 6.15km

 

By my quick test the ABRIS map screen is 156mm wide by 123mm tall

 

Anyone care to check.

The problem with assuming that the screen size quoted is the visible screen size is that often the visible portion of the screen is smaller due to an overlapping bezel. This is often needed to stop backlight bleeding round the edge of the LCD. I think the best way is to measure the actual map using the built in marker/measure tool. (see previous post)

Go ahead. I'm back to other things. I don't even have DDS Plug-in for GIMP installed. Just remember to document step by step your method of measuring. This way we'll be able to verify it.

[Frogfoot1606687865]

Ok here is my method

Select NAV view (Btn5)

Press MAP (Btn2)

Press SCALE+ or SCALE- to set scale to 1cm:1km

Press ERBL

Press MARKER

Twist right hand knob until cross is just touching Left or right of screen

Note measurement (7.81 km)

double it 15.62km , at 1:1 this gives a horizontal measurement of the map as 15.62cm

 

Return cross to center (distance = 0)

Press in knob and move to top or bottom of the screen

Read distance and double it. (6.15km x2 - 12.3km or 12.3 cm)

 

Therefore displayed map is 15.62cm by 12.30 cm

Good

Soooo. Will you put some marks on the cockpit texture? :)

 

He, I knew that pilots had to have some reference! :sly: See the grooves on the bottom frame? They practically match the scale I'm putting on.

 

 

Don't worry. I'll upload the source vector file, so everyone will be able to modify the scale. The background is just for reference. The svg page borders match the texture size, so once you're done with the scale, you delete or hide the texture in Inkscape, choose file - > export bitmap | Page. You'll get a perfect PNG with everything transparent except of the scale.

 

OK, here are the results:

 

Nice from far...

 

 

... but far from nice ...

 

 

 

Something bad happened with the perfect scale. Plus the in-game texture is terribly off what it appears in CDDS files. I placed the scale not closer to the dispay area than 2 mm and here you see - 2 mm deep into the display.

 

There you go

Good find.

 

I would prefer ...

- to make the upper and lower markers symmetric. Now the upper marker starts from the right sight, the lower marker starts from the left side.

- to delete the "2cm" label because you should know the distance of ka50-abris-markers when you enter a ka-50 cockpit.

- to make a version that comes close to the original: only lower markers, nothing else (i would prefer that)

- to put all this into the mod-section

Go ahead, buddy :) What I made is for personal use and I don't have skills to either improve this or assemble it into a ModMan package. Specifically the shape distortion mis not what I can solve. Plus I prefer to spend the time I have on my X52 Pro profile http://forums.eagle.ru/showthread.php?t=53213 rather than this. Long story short - it stays this way unless someone will pick it up.

 

What's most annoying is that it would require painting a grid to determine the real in-game position and dimensions of active ABRIS display. Hmmm, a grid... easily created in Inkscape... damn you! :D

 

Edit:

 

 

 

 

Terrible texture distortion

 

 

 

Look at the texture required

 

 

to get this effect

 

 

Here's the texture mod. Just place the TGA in the Bazar\TempTextures folder. Symmetrical scales version, no "2 cm sign". If you need only the lower scale, you don't need the mod - the caption fields at the bottom are practically the same size :)

Ok, nice. Thxs for the effort. I will use this. Dowloading later.
