Hello

I Have been trying to find the range to distance markings on a A6M gun sight

http://i621.photobucket.com/albums/tt299/Dgirth/il2fb2009-08-2211-27-46-62.jpg


So i can gauge the distance to target, so if i have a plane wing tip to wing tip in the smallers ring is that 500m ? and the outside largest ring being 100m ?


thx for the help chaps!

Why dont you switch on the additional information when having a a/c in front of the reticle?

Hi, i did not think of that as i fly full real. Anyway i have put on Icons but im still a little confused.

I do not understand how IL2 measures in , here it says 47 for the small inside ring

http://i621.photobucket.com/albums/tt299/Dgirth/il2fb2009-08-2215-32-47-24.jpg

The plane is wing tip to wing tip inside the broken ring.

I think the gun sight measures in meters as convergance does.

am i right in thinking the inside ring in 50m ?

That .47 means it is 470m away. So 1.0 means 1km, and 0.1 means 100m and so on.

I don't much about it, but wouldn't it also depend on which plane you're tracking? A B-29 would fill the rings farther away than say an F4F Wildcat.

Right I know what you mean here but it depends on the wingspan of the plane .I think most of these 'ring' systems worked off 10m wingspan. As far as I know Me109 is about exactly 10 m so try put THAT inside the small ring and if its at 500m/0.50km then your theory is correct -similiarly if its at 100m and wingtips are just inside the big circle then you really have it sussed...
Now if you REALLY want to understand this you will look up a guy called "DARTS" video on this topic ...should be linked round here if you do a forum search.If you understand THIS topic fully AND CONVERGENCE you will be a far more deadly fighter pilot...
I dont know for sure about the japanese system but the german /raf and ussr I think have 100m 'big rings' while the US navy I think have a 150m one ....
Now if you REALLY wanna blow your mind check out the K14 'acemaker' gunsight on the P51D-20 (and YP80?) and learn how to toggle the outer ring to 'fit' many german planes (thats why their names are written around the base of that gunsight)Id bet hardly 5% of IL21946 fliers fully understand the K14 acemaker gunsight-me I dont like it all that much!
Good question by the way and Id guess your assumptions are correct by the looks of things just that the zero has a slightly smaller wingspan than 10m

PS Its the 190 has the 10m wingspan not the 109

100m convergence + fighter wingspan touching the '100m' ring = Devastation

thanks for the replys

I been messing around with my convergance settings while using the rings to aim and judge distance.

I fly jap fighters in =JFC= online campaigne and nearly all have the same type of sight.

So far i have found 500m for cannons and guns to be the best IF you use the sights and distance range right.

Its powerful at 50m and 500m. I found 100, to 200m not effective, if you judge the distance wrong your bullets will meet and pass each other going wide of the target.

If you judge it right your opponents wings will fly off and his fuselage will break in half from a short burst.

This is A6M2-21's Rangefinder as i have calculated it, in IL2 Sturmovik using various planes. It seems it is a 100 mils (http://en.wikipedia.org/wiki/Angular_mil) rangefinder. This means that if a 10m-wide target fits wingtip-to-wingtip into one of the circles, its distance will be the indicated one. Ex. if you have a 10m target (FW-109) tight inside the <span class="ev_code_GREEN">GREEN</span> circle, it will be 100 meters away.

Wingspan data (Plane, WingSpan):
<UL TYPE=SQUARE> <LI> SBD 12m
<LI>F4F 11m
<LI>F6F 13m
<LI>P-40 11m
<LI>P-38 15m
<LI>TBF 16m
<LI>
<LI>A6M 12m
<LI>Fw190 10m
<LI>Bf109 9m
[/list]
ALL wingspan lengths are rounded downwards so as to achieve the safest results. FW190 is 10.5m but indicated as 10m so as to be sure that it is NOT more than 100m away if it lies within the outer circle.

See wikipedia MILS for more information: http://en.wikipedia.org/wiki/Angular_mil

OR

a second explanation:

http://i202.photobucket.com/albums/aa220/klapatsimbanos/a6m2-21_rangefinder_mils.jpg

The distance between you and the object you see in the scope will be "X" times the object's wingspan.
Example:
A P-38 has a wingspan of 15 meters. If you see a P-38 wingtip-to-wingtip in the x10 circle, then it will be [15m]x[x10]=150 meters away.
[Distance] = [Actual wingspan] x [circle's multiplier]

Hope it helps!
