Default VDI/HUD symbology for missile launches

So my friend and I were in the Tomcat practicing the radar and flying intercepts against another friend in another Tomcat.



When he locked up the other plane, I got a bunch of symbology on the HUD and VDI that I didn't recognize. I think I was able to figure out what it all did, but I was hoping there was a guide somewhere that I missed that told me what it all was. To know the actual names and functions behind the symbology. There is somethat's explained in the manual in ther A/A weapons section, but what I'm looking for is all the extra stuff, mainly in the VDI, like the vertical bar, the small T, and the black circle. In hindsight I guess I should have taken a screenshot, but things were moving very fast at 1200kts closure lol.

Yea not sure about the black circle and the small T, (I definitely know what you are talking about though) but I know for a fact that the vertical bar on the VDI is just for steering purposes. Keep it centered and it will put you one the best intercept course.
I'm pretty sure the manual does talk about the vertical bar but I didn't see anything about the growing black circle or small T either...

Does the manual explain the various symbologies on the HUD for various modes. I cannot find it in there.

All the symbology on the VDIG is roughly analogous to the F-15 or F-18 which you may have seen before.

The small inverted T is the steering cue, in otherwords putting this in the middle of the display means they are directly ahead. The expanding circle is the Allowable Steering Error, this will expand as range decreases and gives a representation of the initial turn any weapon fired will have to make in order to get onto an intercept path.

In other words center the T and then shoot.

Comparing to the other jets this is shown on the HUD or radar display, with a dot instead of a T.

The long green bar is the weapon range scale with ticks on the right of the bar representing rmax and rmin for the current weapon and the tick to the left the current range to target.

Again this can be seen in a very similar way on the HUD or radar display of any other teen series jet.

This is what I figured it all out to be, but it would still be really neat to see the write up on it and how to use it with the RIO to intercept and not necessarily fire on targets. Just nice to see the documentation on it. I'm really excited to see HB expand on the manual, especially since the online version has no restrictions like the PDF has with regards to update schedules.

Unfortunately not, although I found that info in the NATOPS manual.

No idea how RMax values are calculated though, they seem to overestimate missiles range at least by a factor of two for AIM-7.

Thanks
The Aerosoft version of the F-14 has some good manuals with relevant explanations of all the symbols. Those I am reading to get myself acquainted with dcs F-14.
