[REPORTED] EZ 42 remarks [0027501]

To be honest I don’t think so this is the EZ 42 crosshair (or this is the part of EZ 42), it is missing any evidence of damping system and for me It isn’t looking similar to picture in manual (servo motor in EZ 42 was behind the mirror see attachment). In manual is EZ 42 crosshair clearly visible. Also on your picture is clearly visible 10% ring used on standard REVIs for distance calculation so it is looking they used mask from standard REVI because you don't need this on gyro gunsights (maybe after gyro failure ) for me it is indicating experimental or prototype.

You must consider one thing in reality German development of gyro gunsights was running from early 30s and there was lot of experimental gyro gunsight like EZ 2, EZ 6, EZ 31 (and more), some gunsights also passed the gunnery trials like EZ 40, EZ 42 and EZ 44, and some future planned like EZ 45 so there are many opportunities. From my knowledge I am guessing this is from EZ 40 (but Askania EZ 40 not Carl Zeiss), because there was 0.serie production (also trials at field units) and crosshair on EZ 44 was different (when you consider only gyro gunsights produced in more than 10 pcs) ….

When will we get a fixed reticle for EZ-42?

 

Without a fixed reticle, I'm not able to do deflection shooting, which the butcher bird was famous for and their pilots were proud of.

 

If I had a fixed reticle, I would be able to kill the mustang within 5 minutes. I can't remember how many opportunities have slipped away from my hands.

 

P. S. How can I display TAS of Dora?

As I'm reading through my book "He 162 Volksjäger - Letzter Versuch der Luftwaffe" i found this 3 sentences at page 371 about the EZ 42:

 

"Das EZ 42 wurde im Herbst 1944 von der Firma Askania in Berlin fertig konstruiert.(206) Es war für den Zielbereich von 80-1000m geeignet und wog 13,6 kg. Vorgesehen für die Heinkel He 162 war der Einbau ab Mai 1945.(207)"

 

206 - Unterlüss Report 295/VI, Page 8

207 - Protocoll KdE from 12.2.1945 Pt. 12

 

"The EZ 42 was final constructed in autumn of 1944 by the company Askania in Berlin.(206) It was applicable for a target range of 80-1000m and weighted 13,6 kg. For the Heinkel He 162 the Installation was scheduled starting May 1945.(207)"

 

Ingame we have a range from 10m to 1000m.

To me, this looks like a typo. 10 km range? No way... You barely hit a barn at 1 km due to spread - why should the aiming device be adjustable waaaay further than that?

 

(edit: you "corrected" that typo already yourself in your translation ;o)

Text says 1000m, but finger went one time to often down at tipping. Sorry.

Heh, allright. But what is then your criticism? The minimum range, 10m vs. 80 meters?

 

Btw, where did you get the 10 m from - the manual? The range scale has an unmarked tick for less than 100 m, but the scale seems to be not linear. So it could very well be marking 80 m.

Under /mods/aircrafts/FW-190D9/Cockpit/Scripts/Gunsight_EZ42/device

looking into the EZ42_param.lua told me:

 

Dmin = 10 << should be 80

Dmax = 1000

Dmin2 = 250

 

Lmin = 10

Lmax = 40

 

:music_whistling:

 

Another bug is the Reticle vanishing behind the "bar" by moving your head closer to the Revi.

Also the 1% open cross in the middle of the Revi never changes by increasing/decreasing distance or wingspan.

Reticle reflection of a EZ 42 Revi.

Notice the extended lines outside the ring and the degree marks.

 

From http://www.cockpitinstrumente.de by selling items (but already sold)

I always thought the EZ42 reticle looked a bit odd in DCS. You should report this. I would much rather use this as a sight than what we have now.

Guys it is replica :)!!!, probably they used same shape of recticle like REVI 16 have. For gyro gunsight this recticle shape don’t have any sense (maybe only when gyro is destroyed). Source for current DCS recticle is EZ 42 manual….

It's a replic yes.

 

But the manual doesn't show the real reticle either, since it's mentions the degree scale which isn't present in the 6 reticle pictures.

 

Here the text from page 5 of the manual:

[ATTACH]106859[/ATTACH]

 

Good point Kodoss, I have read manual few times but never think about this sentence. It is for me little bit mystery because also in attached schema from manual is recticle showed like on all another pictures. Generally in all REVI manuals is always recticle shape displayed according to reality, usually also explained... Maybe they planned use different shape from start of project (they were lot of changes) and they forgot to change this sentence, or they planned use different shape of recticle for fighter bombers (Me-262A-2)??? In my opinion is recticle Ok, according to reality. It don't mean your suggestion can’t be right, without analyse of real EZ 42 we cannot be sure….

Another document which states the degree scale, see the red marked text.

 

EZ-42.thumb.jpg.9dcf428475aece901f41d9b66ddfb01f.jpg

 

They planned 2 EZ 42 sight version, one for fighter with degree scale EZ 42/1 A-1 and a gunner version EZ 42/2.

The last one is mentioned in the manual with giving the respective manual: D. (Luft) T. 6414

They were planned an also tested another two versions of EZ-42 one was EZ-42SP (Selbsttätige Peilung - I haven’t translated whole document so I cannot explain it functionality) and EZ-42 with radar setting of distance using FUG217 radar as part of OBERON system. I have document what you have posted, it is overview of German gunsight development ... For me it is hard to believe all German REVI manuals are showing real shape of recticle only EZ 42 is showing false shape... By the way main competitor of Askania EZ 42, Carl Zeis EZ 44 has only 8 dots as recticle without any helpscale for bombing. For bombing focus was on TSA2...

Documents presented by you and me are indicating different things, so as I wrote before - without analyse of real EZ 42 we cannot be sure….

EZ42 issues

 

I found a few (potential) issues with the way the EZ42 is modelled in DCS for the Fw 190.

 

1. EZ42 Ballistics Adjustment Control Box (right panel)

a) Is it functional at all? I could not see much of a difference of the reticle placement when playing around with the settings. But that could also be because ...

b) The default settings are that both rotaries are set to "0", but only rotary I can be used by us as the rotary II is seemingly hidden under a cover and is not clickable. The problem here is, that according to the attached adjustment table, rotary II should be set to "63".

attachment.php?attachmentid=111751&stc=1&d=1421841541

d) Why is the rotary II not adjustable by the pilot? The table suggests, that there is only one setting necessary - but the Luftwaffe manual shows an example that, while the values for rotary I are quite the same, rotary II is to be set to different values as well.

attachment.php?attachmentid=111752&stc=1&d=1421841541

attachment.php?attachmentid=111754&stc=1&d=1421841541

2. Reticle not correct?

The adjustment table, which is attached to the control box, hints that we have an EZ42/A1 in our Fw 190. According to the Luftwaffe manual, this version should have an aiming cross with tick marks (in degrees) to help aiming/estimating the lead when dropping bombs.
