>>> GUNASIGHT - 50 MILS GYRO SIGHT <<<

This situation worries me because the gyro range, among aircraft are different and can cause us to miss targets when using gyro sights.

Therefore, I started tweaking the Gyro sight based on 50 MILs.  As stated, there is no dynamic expanding / shrinking gunsight for early cold aircraft, so all gyro sight is fixed as 50 MILs.

First, I want to tell you what I learned about MILs size:

MILs stands for milliradians.  It is an angular measurement.  1 MILs = 1/1000th of the distance to the target.

Simple formula for math:

Size (in meters) = (Distance in meters × MILs) / 1000

With 50 MIls sight, at 100 meters distance 
(100 x 50) / 1000 = 5 Meters target size

50 MILs sight, 1000 Meters distance 
(1000 x 50) / 1000 = 50 Meters size

However, there are various aircraft with different wingspan sizes.  So it all comes down to what is most common targets that each aircraft faces or most likely.

For example, F-86s, the most common target would be MiG-15, not Tu-95.  Same with MIG-15, the most common or likely target would be F-86 rather than B-29.  That is how I find the practical range for gyro sight based on aircraft and common / most likely target.

Here is an example:

for F-86's Mark 18 / A-1 / A-4 gunsight at 50 MILs and the wingspan of MiG-15 being 10 meters.

Formula:

Range = (wingspan of target x 1000) / MILs size

Range = (10 m x 1000 m) / 50 = 200 m

Therefore, the F-86F's 50 MILs gunsight would have default range of 200 meters.

And for MiG-15's ASP-1N / 3N gunsight:

NOTE: F-86F's wingspan is 11 M

Range = (11 x 1000) / 50 = 220 meter

Finally, there are three codes to look at from cockpit.ini:

(For rangefinder / radar based gunsight)
MinLeadRange=
MaxLeadRange=

(For non-rangefinder / radar or not using radar)
DefaultLeadRange=

After the projects with MIGs / Js are completed, I plan on re-visiting all of another aircraft's gyro range based on the data and flight manual.

>>> VIEW / CAMERA SYSTEM OVERHAUL <<<

The works on AIRCRAFTOBJECT.INI allows me to edit the view / camera to give you more realistic feelings of flying aircraft.  Based on the work of Warbirds's Realistic Head Movement base, modified it so the head movement is not as dramatic.  Since in the early cold war aircraft to modern, the pilots are tightly melted on the chair, as well have Gs suits.  Spent a lot of time testing and tweaking it.

Hello everyone!

I have been working a lot on adjusting the minimum and maximum effective range of various guns for aircraft I have worked on so far in SF - CAP.

Here is table I created as reference to help me figuring out the minimum and maximum effective range, as well the default range.  

NOTE:  As stated before, the default range is usually 200 meters, unless the minimum effective range is above that, then that is used instead fo 200 meters.
 

 

I wish that Thirdwire would have added dynamic gunsight (expanding / shrinking) because there is P-51 /F-51, as well F-100 and other that would have used it.  Since SF2 does not have that, I choose 50 MILs as default size for these type of sights.

Now that is completed, I am able to t move on to next aircraf.t  I am currently working on Mirage III series.  There are still more work to do.  Here is CFS Type 97K sights:

FIXED SIGHT

 

GYRO SIGHT

 

ROLL TAB (WINGS)

 

HEADING SCALE

 

SF2 screenshot (WIP - still have more to work on.)

@dtmdragon

Great information!  I also have the information I would like to hsare with you too:  I need the information for Israel Mirage IIICJ "Shahak" and IAI Nesher.  they are great help for the projects!

From what I have learned, it appear that Cyrano I bis and Cyrano II have some difference with the optical sight layout.  It looks like Cyrano II have horizontal line (wings) which is used as roll tabs, linked to gyro sight, along with the closure speed scale.  Cyrano I bis, in other hand, only have gyro sight, fixed sight, and hheading scale which also act as range scale.  (As always, feel free to correct me if I am incorrect on any information).

By the way, the optical sight I am working on is based on Mirage IIID and E, based on the information from Mirage IIIO - D flight manual.  Here is information from the manual.  If you want this manual, I can send it to you by PM.

I forgot to add one more notes about the color of opitcal sight.  A freind of mine helped me researching and found a great video.

Screenshot from video:

(The optical sight cxan be seen from 11:00)

 

[+Eagle114th 964]

Found two fo very important pages for optical sight layout. I am re-working on the optical sight layout:

Thank you Dtmdragon, while studying the sight you did for IAI Nesher, I noticed that the gyro sight is above the fixed sight, got me going through the manual again, then found these two pages!  Just like I said, your files are a great help!

Hello everyone,

After gong through manual and I realized that, the nature of CFS Type 97K is very dynamic with the gyro sight, moving veritcally depending on the mode and air to air combat situations.  Unfortuantely, in SF2, it does not have dynamic sight mechanically.

Therefore, I have no choice but to remain at 0 depression for gun.  However, I moved the layout around to match the manual at zero depression for air to air.

NOTE:  This optical sight is for Mirage IIID / E / O with Cyrano II radar.

 

The most interesting part about AG mode is that, according ot manual, for bomb attack, the gyro sight is depressed at 111.5 MILs. I tested it, turns out it does match the manual layout.



However, for the rocket attack, it is depressed at 45 and it aligns with the rockets:

And the reasons why I set it to 45 MILs depression, here ione page that talks about "EVELATION AND GRAVITY COIL":

 

While the diagram in previous posts about G / R / M mode (Gun / Rockets / Missiles) set at zero depression, it stil have the capable of depressing from -5 to + 45 MILs., thherefore I set gyro sight to 45 maximum for rockets, which aligns with rockets as shown in screenshot.

 

By the way, I am still workiong on adding the clourse speed for AA mode.  However, I am still researching to see if I could add scale version. I posted the questions at this link:


 

 

I plan on wokrong on earlier Cyrano I bis version for early Mirage III series, including Mirage III CJ "Shahak" series.

I suppose is not possible without working with the exe, but have you tried to add "slewable" radar cursors to the player?

Hello Stratos! It is great to see you here!  I am not sure if you remember me, I posted at our forum we used to chill long, long time ago. It was C5 forum, along with Dave, Falc and other members.  It is a great memories!

So seeing you here brings me great joys!

By the way, to answer your questions; I have not yet figured out how to edit the .dll nor .exe files of SF2 yet.  I am still puzzled by it.  From time to time, I take a look at the files using Ghidra.

By the way, I planon sending you PM.

Hello everyone!

@dtmdragon

I finally found information on the early Cyrano I Bis gunisght, it was quite challenging to find, it is from Mirage IIIB manual (Plates) and I finally understanda bout the horonzital line. You are right, there is no horizontal line during dogfight.  For examlpe, with Cyrano II's version of CFS Type 97K gunsight, the wing (Horzintal line) appear only if it is beyond 1.1 MN, and less than that, it disappear.

I Now with more information on both Cyrano I Bis and Cyrano II gunsight, There will be three modes:

NAV, AA, and AG. I usually use NAV to 'turn off sight" for pre-HUD era aircraft.  This time, Mirage III have unique and many uses of gunisght, therefore, for NAV, the gyro + fixed sight will be fixed with horizontal line.  for AA and AG, tehre is no horizontal lines.

However, here is pictures from Mirage IIIB manual (Plates):

It is a far more advanced sighting system than I realized with the wings serving as steering cues among other things depending on the mode etc. It's a shame SF2 can't replicate these kind of avionics

I agree! It is quite frustrating that TK does not realize the amazing potiental of SF2 earlier.  However, at least, we grow more knowledge with the hobbies we have here.  Prehaps someday when new sims that are like SF2 comes out, we can bring all of our hobbies over there too! I hope someday.

For now, in meanwhile, we do what we can do with SF2.

Hello everyone!

The optical sight for Cyrano I Bis radar are now completed.  Please note that, this Mirage III is unique with many advanced features for optical sights.  So this time, for NAV, instead of having 'turned off" optical sights, the horizontal bar, linked to gyro sight is used for navigating. AA and AG mode does not feature that.

By the way, here is screenshot of Cyrano I Bis radar optical sight (Mirage Cs and Shahak series):

NAV MODE:

AA MODE:

AG MODE - GUN and ROCKET:

 

NOTE: I didn't realize that the 2 vertical small symbols below the gunsight aligns with the rocket.

 

AG MODE - BOMB (Depressed sight)

 

For Cyrano II optical sight, it have been re-done, so the horizontal bar will only appear in NAV mode while further fixing and polishing the optical sight systems for AA and AG.

NOTE: for AA mode, the clourse speed is included.  Unfortunately I do not know the way to add scale version of clourse speed, so we have dynamic speed for now.

NAV MODE:

AA MODE:

 

AG MODE - GUN and ROCKET:

AG MODE - BOMB (Depressed sight)

The radars are being worked on for Mirage IIIs, Shahak, and Mirage IIIS are work in progress now.
