Open flight manual and point at this mode of launch
It’s NOT in manual, because that mode it’s just a unregistered feature - not a main mode of work.
As the text says, this head is inertial guidance with radio correction (which is NOT radar guidance) + IR seeker. (All R-27’s have same accumulator, guidance scheme, and other stuff - only a seeker and booster/sustainer can be replaced due to needs).
Reason
Therefore, in the course of development for missiles with radar GSN specialists NIIP based on the results of research adopted a combined scheme of operation with the ability to capture the target on the trajectory.
So, as 27R/ER can be launched, and guided by inertial guidance to the terminal part of trajectory - 27T/ET can do same, because of same “brains” onboard.
(R-24 can do almost same, because of inertial guidance (more primitive, but still better, than Sparrows “english” correction), BTW, but only radar version, due to more primitive guidance scheme)
Story from same guy
An former LSK MiG-23 pilot explained it to me in that way. “You find the target with the radar or the IR seeker of the plane, get all needed information for launch. Then send the missile on the way to a calculated point and unlock the target (go back to search mode or even switch off the Radar). For the IR guided missiles you must do nothing else because the seaker will (hopefully) find the target on the pre calculated point.
For the semi active seeker heads the activation point is 6 to 10 km away from target. When the missile comes to this point you must lock on the target.” This was called “silent shot”.
Ok, now, to the past theme.
Now, about the "special" MiGs for 27EA/EP...
Еще до постройки первых МиГ-29М для отработки вооружения и оборудования новой модификации ММЗ им. А.И.Микояна подготовил несколько опытных самолетов - летающих лабораторий. В целях дооснащения истребителя ракетами РВВ-АЕ были переоборудованы два серийных МиГ-29 типа «9-12», получившие №970 и 971. Первый полет МиГ-29 №970 состоялся 24 декабря 1984 г., МиГ-29 №971 - 12 августа 1985 г. Испытания их продолжались до 1989 г., на 970-м выполнили 286 полетов, на 971-м - 204 полета. Последняя машина в 1986 г. использовалась также для летной отработки новых модификаций ракеты К-27 с пассивной и активной радиолокационными головками самонаведения. Для испытаний ракеты РВВ-АЕ привлекались также первые экземпляры МиГ-29 - самолеты №919 (с мая 1984 г.), №923 (с декабря 1984 г.) и №925 (с июня 1985 г.).
So, as we see, they modified planes for R-77 usage, and use same ones, to launch R-27EA/EP, which proof the ability of R-77 carriers to use a 27EA/EP.
(I haven’t any idea how - i ain’t the guy, who make software for those planes. Maybe, somewhere in those machines really been soft for 27EA/EP, or, just R-27EA, recognised by plane as R-77, and only God (and coder) knows, how recognised 27EP (maybe as radar version R-27 - in the end, it need just be launched, not guided).
Planes recognize 27EP as 27EP, EP was adopted and integrated into software
Words proof nothing
Modified experimental planes had avionics both for 27EA and R-77, does serial preserved soft for 27EA?
Cool story, bro.
This describes the procedure for guiding a missile with an IR seeker using radar or IRST data. The missile searches for the target in the specified location, and if it finds it, it locks on with its seeker, and the pilot gets a ‘launch’ indication on the HUD. This is implemented for many aircraft in the game."

Well, i aint seen that in Flanker flight manual. Maybe you can show me?
Look into spoiler, to what Flogger pilot said, about “silent strike”.
If you looks into spoiler, not just answering my conclusion - you can see, that MiG-29 №970, and 971, been modified only to launch R-77.
There no more modifications to launch R-27EA.
That means, plane, who able to carry R-27, and launch R-77, CAN use R-27EA.
Book 1, page 102, section 5 ‘Combat Use’.
No.
If you have a proofs, why can NOT do this - you more than welcome to show them here.
Well, yes, but no.
If you read all the text, you can find:
…and that not, how standart procedure (seeker lock - then launch) doing.
Here, he explain how…
…where missle, by herself (if lucky), will find and lock target.
You have 0 proofs of that, except of some “expert” stating that is.
It is NOT stated in manual, where all other weapon systems are.

You forget to link the manual.
I can to said “look in (yadda-yadda) book, (yadda-yadda) page, (yadda-yadda) section” too.
What a proof.
And what proof states that any carrier of 77&27R can use EA?
First, provide proof that this is possible. What kind of idiocy is it to demand proof of absence? Provide me with proof that the Su-27 cannot fire a Phoenix.
Every missile is directed to a calculated intercept point after launch. What you’re talking about is called lock-on after launch, and there’s not a word about it in the story you provided.
You need proofs, for explaning standart procedure of launching Fox-2?
Well, on .ru, that going as “popytka dojebatsya”.
Try better.
Standart procedure for R-27T is LOBL.
You trying to state that it can into LOAL with IOG, but without proofs.
You need to ask about that. The excerpt states that two aircraft were modified for testing new missiles. The second one was also modified for testing the K-27 family of missiles.
Already done.
I won’t re-type a bunch of text, for those who are too lazy to just scroll through.
That calls “logic”. And historical proofs.
If for you it’s idiocy - the problem is you.
Well, Phoenix can’t be launched by APU/AKU-470.
Too easy, try more.
All that time, i told you, about LOAL, if you read properly (ain’t be too lazy), you can even find it.
Words of random guy from internet is not a valuable proof.
Nothing of the sort. Your ‘I want to believe’ is not proof.
What a proof.
I don’t need stories about this from you. I need proof that the R-27T is capable of lock-on after launch. That’s all.
You always can use adapters, same type as HARM on Su-27.
But, electronics cant, same with 27EA on all R-27&77 launch aircraft.
this might actually be a counter to the Aim-120C-5/7 before we get the 120D and the 77M
Loal - maybe possible, but without IOG usage, just dumb fire like a S-8 rockets
