Missing function from the HUD for all Flankers!

F-15C will lose the target. F-14A/B will also lose such target. Doppler radar feature.

Stop playing unrealistic missions and try cold war servers. 120A was in short supply, barely deployed, not worth modeling.

Su-27/33 and MiG-29 radars in DCS loose track in a look-up situation unless you switch PRF which you have no indication of.

Su-27/33 and MiG-29 have exact same notch speed. While MiG-29 radar is very poor in rear aspect (18-30 km), it will lose targets in notch equally 

And about the timer, we have these other mentions of it being the 60 second timer for the whole generator 

For example, if it is really TTI, what is this command based on? If it is based only on TOF given to missile before launch, it will be too long or short depending on target managers. Does compete calculate change in TTI as target maneuvers? 
 

I find this hard to believe, so I really think it is 60 second timer, but if it was true TTI with real time post launch calculation, that would be immensely awesome

The bible does not mention how it does it, just that it is the time-to-impact indicator. What good would it be if it's only a 60s timer, if you fire at Rne for example?

TTI would have operational value as you could potentially disengage after the timer runs out.

I will have to try and read more about it...

There is no notch in a look-up, as there's nothing to filter out.

Yes, but we aren’t talking about only in look up. And it is only after 3.5 degrees of look up that the notch turns off, something we have to guess

I can see why the designers would see 60 second timer as useful. So even if target goes cold at high altitude, you know when missile is truly dead and can abandon it. I doubt the TTI would be perfectly accurate as target maneuvers and estimated missile position might not be perfect

АП Mark should remain when jamming target is locked in stt, currently it is there in search mode if there is active jamming but disappears when you lock the target.

It is important for it to remain since it gives clear indication if you can employ R-27Rs in HOJ mode.

 

You should be able to receive jamming angles even when radar is not emitting, for the same employment

I am still to dig out more information about it, but I am failing to understand why would it be a problem to calculate the impact time? The targeting computer already calculates in real time the launch zone parameters.

To me it’s more about, it can calculate parameters before missile launch. But after a missile launch occurred and the target maneuvers, I would think calculating that and having to estimate how far the missile has traveled and at what speed, would at the very least introduce some amount of increasing error. 
 

All the proportional navigation is done in the missile, but this would be vital information to estimate missile position after target maneuvers 

[draconus]

It's not something impossible, at least to have a TTI number in seconds, but it would simply need datalink to share the info between missile and aircraft. Also consider usefullness of this data in a very dynamic profile like this: 5 seconds TTI, target perfoms spit-S, TTI rises and then never reaches 0.

I'm not sure why you guys are treating this possibly TTI function as alien technology, as if its impossible to just give a rough estimate time based on initial launch parameters regardless of target maneuvering. You know, just like ED has already modeled for the F-15C.

In the F-15C you get a countdown that does not update mid-flight, be it for the Aim-7E (that definitely has no datalink) or the Aim-120C, and while it normally miss the counting by a few seconds even for a non-maneuvering target, it is still quite useful, helping you to judge whether you keep guiding the missile or evade the enemy's.

Yes that makes sense to me, in regards to “original” launch conditions. But its limitations also bring me to how some sources have said it refers to “power limit,” as ultimately no matter what happens, it can’t fly longer then 60 seconds and the pilot can be 100% sure it’s dead 

[Ironhand]

FWIW, the Russian SK manual that’s floating around refers to that line as “Time, remaining until missile meets the target.”

Look how the line is much smaller from the begining. That shows that it takes the geometry into consideration and is not just a pure representation of the 60 s timer.

Very nice find! Excellent feature
