AS RPC is required before launch, as the CVK should select a flight program of the SRP from the available 97 (flight program number 104..201).
On the other hand you can launch with AS-2 also, without measured range or speed information.

Just refreshing memories: Easiest answer is that Plamya use different program codes, for the different tasks.
(manual page 17)
Plamja-KV CVM (digital computer)
The digital computer has a 16bit processor, running at 64kHz frequency.
It has 256 bytes of RAM, and 4,096 bytes of ROM.
It has five built-in programs:
1. Idle
In this mode, the Plamja-KV is calculating the firing solution using the instantaneously available data from the RPC.
2. IADS target acquisition
In this mode, the Plamja-KV is interpolating the target's predicted position, between the 10Hz updates received from the IADS information.
3. Target tracking
In this mode, the Plamja-KV is continuously calculating the target's predicted path, and figuring the firing solution based on this information.
4. Tracking Jamming Target
In this mode, the Plamja-KV is calculating the firing solution using a manually preset target range. This mode is called AS-2.
5. Self Test
I think, that CVK always DO a firing solution, no matter how the data is inputed on it (manually, by "local sensors" (those MD buttons and red lights) or by IADS. The real behaviour of the system is a mystical process for me, understanding the behaviour is a key for a bug findings or some mistery solving (04.10.2001 - Tu-154M)...

Yes, the poor Tu-154, I do not understand if the measured range was real range of VR-3 how the missile could get so far. Maybe error of a tracking officer who mistakenly entered wrong range?

Yes, the CVK for a launch must have some range information, but in SAMSIM when I completely track target, then I switch AS-RPC off, PROLONG is thus active and apparently CVK is not computing track range data. But I am able to launch and successfully kill the target. So in this case CVK seemingly has the last range information and uses it for the missile.
Because when I track the target only in velocity, I am unable to launch as there is no any (even not some last estimate) range information.

Maybe we could move the last posts into a Vega theme.

Do not mix Plamya-KV (CVM) programs (5) with the available 97 flight programs of the SRP.
Before launch, CVM in program 2 (IADS - AS4), 3 (P14 - AS4), or 4 (Jamming - AS2) should supply onboard SRP with the selected flight program 104..201.

SA-5According to "Manual of battle work of S-200B", page 146,- "RABOTA PO V" knob must be in "AVTOPEREZAHVAT VIKL" mode by default.... Link

So, does it mean that it must stay wrong??? As it is like now, we had AS on epsilon/beta only...

SA-5:
On Tallin scenario, managed to shoot at receding SR-71 and got it down... According to manuals, we could engage receding targets with 300 m/s....

Hmmm, a lucky shot. As target and missile speeds are almost equal (1000 m/s), thus most of the time the return signal frequency would be with ~ 0 doppler shift, i.e. targt cannot be tracked successful

And what if you can not track it.
�Target speed of almost 1000 m / s this is true, it is strange that in Operation Tallinn grab this goal is very difficult, I tried a lot of times, it was possible only very rarely.
�Strange if another shoot at moving away goal, then the maximum speed of 300 m / s, why do Volkhov then 420 m / s, Volkhov system older than Vega rocket and she also weaker.
�At the C-200 'Vega' Hypersonic missile, the idea should not be a problem, it just easily catch up with the target.

No idea... Probably due to SARH method...

-----------------
Total, SNR On Air Time: 8min 21sec TL;DR Shot down a Blackbird with an SA-2F  . To be fair though, something must've glitched because the jammer wasn't on, or at least not having any effect on me. I'm guessing the same goes for the various other anti SAM systems that have been mentioned in this sub forum if they're modeled as well.
