Gunsight vs. HUD

[Nyghtfall]

Hey there,

I've come back to a topic from the past lately.

Is it possible to replicate the Gunsight-functionality with a HUD in SF2? If you have a Gunsight, than you have a simple reticle for guns, that is depressed down a bit for unguided rockets - not lead computing, CCIP, whatever.

I would need that Gunsight-functionality together with an additonal marking for a laserdesignated Target.

At the moment I have the Reticle + Targetmarking showing, but the Reticle doesn't move if I select unguided Rockets.

In the past my workaround was a new Reticle that has 2 aimpoints - guns and rockets, so no movement was needed.

My Settings from Cockpit.ini

You could use a keyboard letter assigned to the separate 'guns or rockets selected function' eg the + key. The location is defined by co-ordinates like the location of the airspeed number etc. I did something similar for the GR.3 revisionary sight for the Falklands campaign. The sight was basically a big lowercase 't' with the horizontal line changing position depending on guns, bombs or rockets being selected. For this I had a vertical line that came up in air to ground mode and the horizontal lines are made up of multiple underscore lines together: ____ called up by the bomb/guns/rockets selected text with the position moved by the diffrent coordinates for each type of weapon.

Interesting, I didn't know that was possible. I guess, I can build something with that.

After re-reading the tiny bit of information available about the realworld counterpart, I realized, that I don't have to rely on the original gunsight-reticle, since the gunsight was exchanged for something from Ferranti (no designation or type, probably even experimental). Pics are also not available, so I will just do something that works. Thanks for your help!

What aircraft/ gunsight are you doing? Not the experimental Australian Navy A-4G air-to-air sight (by Ferranti) by any chance?

No, one of my first mods was the A-4F from VA-164 with the laser spot tracker in the nose (targetdesignation was from backseaters of TA-4F). I never liked my workaround with a double-reticle for guns+rockets.

Seems like the Gunsight, that could show the designated target was from Ferranti too. Unfortunately I didn't find any pictures, type or name of it and I think, that there aren't any, given how little detail you find about the topic.

 

Didn't know about the Australian sight. What's up with that? While searching for the experimental one above, I found 2 brochures about the Gunsights, that were used in 2 the batches of Singaporean Skyhawks from the 70s (A-4S and A-4S-1) - also from Ferranti. Maybe there's some sort of connection? Ferranti obviously was quite active... ;)

Trial was in 1971 with the Thomson (Ferranti) C.S.F. R22 Gyro Gunsight. Picture, PDF and info here:

I think I got it. Thanks Dan for your help!

That's great guys, love your works!

This can be adapted to other planes ; I remember reading somewhere that the F-4G had a similar system indicating the selected target for the HARMs, but don't rmember the source...
