The medium range missile:
R-27R and ER variants can be used in any meteorological conditions. Launch can made at less than 5
g overload and less 50 deg/s roll rate.
[3] It is allowed to redesignate targets during flight, or sharing target illumination with other aircraft.
R-27T and ET variants can be used out of cloudiness, at least 15 degrees away from the bearing of sun, and 4 degrees away from the bearing of moon and ground based head-contrasting conditions. In cases of maximum head-on range launches where lock-command cannot be utilised, missile can be fired in PPS: In this mode, missile will fly straight until achieves target lock. As missile lacks capability of maneuvering before lock, aircraft itself must maneuver so that missile will be pointed to no more than 15 degrees bearing of the target for confident capture by the IR seeker after launch. Equalising altitude is recommended but not required.
[4] On combat operations section of the Su-27 manual, this mode of usage is especially recommended for head-on usage for passive attacks at targets with 0 degrees approach angle (i.e. another fighter moving to intercept), leaving target unalerted to incoming missile.
[5] Launch can be made at 0 to 7
g, but limited to 6
g if roll induced slip is more than 2x diameter of the ball.

As you can see, ther is lack of software and hardware. What i now is our amraam can be fired with two modes. You can target the missile and guidance with the radar of the figter untill it is near the enemy. Or you sent the missile with automaticly lockdown, the missile fly wher you have programmed with a radar seeker. But you have chance to mis the target with this mode.
So every Russian BVR missile have to lock on, hitting a missile from 250km ask a powerfull radar. Big rocket engine and very good hardware in the missile. As we can see, the russian medium range missile lacks on radar seeker, so they are using infrared seeker. How effective is that? They have in the front of the fighter IRIS to lockdown, how good can you site tracks?
In Russia there is a saying, "Stupid like a Turk
