While the acceleration suffers from the mass, the top speed is more affected by drag (R-27E with long burntime has enough time to accelerate). Then it will fight the drag using its kinetic energy, and for that it needs some mass. A missile with the same shape that weighs 1 gramm would not go very far, even from mach 5. Weight should obviously not get too high either.

I don't think that the R-27 is inferior to the Aim-120 in terms of aerodynamics and kinematics. With a lofted profile it would reach crazy ranges, because it gets much faster than the Aim-120. The added weight would help it to maintain its speed against the higher drag. With a loft the brochure ranges of 120 km are perfectly plausible.

The Su-27 is using the notch-cheat. Highly illegal!

We are friends, not foes! Unfortunately we have to write in this forum, the other threats in the english forum don't get the same attention by ED. In previous version of DCS, chaffing and then turning through the notch was often enough to defeat the missile. When the notch was entered, the missile would go for a chaff more often than not. This no longer seems to work, it may be as a result of the change in autopilot. When going through the notch the missile may go "blind" and is unable to see chaff.

No, it is about 120B+C being buggy right now with basically complete chaff resistance, and ED not admitting the bug (Note: Chizh said that chaff resistance should be similar as before the patch, which is absolutely not the case right now. Reminds me of Aim-7 that had a bug where it was unchaffable). Could it be different between Aim-120 fired by AI and Aim-120 fired by a player maybe?

I think the RPPK should be RLPK, which is simply the radar complex. Russian L and P look somewhat similar.

As the developers already said, the range increase comes from much less drag when maneuvering. Against a straight flying target not much has improved, but when it maneuvers it will keep its energy better than it did before.

I meant the real aircraft manuals. FC3 is after all very simplified.

You said that the chaff rejection should be similar to how it was, but this is not the case at all at the moment.

Thank you!

Hi! I have just done very few tests, but I had no Aim-120 going for a chaff. The chaff rejection must be magnitudes higher than it was before at the moment. Chizh said it should be similar to previous DCS versions, so it is definetly not working as intended right now.

You RWR is not indicating the missile launch, it is indicating that the radar is in SARH target illumination mode. He was still guiding the missile fired earlier, so you will still receive the SARH illumination once he relocks you, or once you maneuver so that the RWR picks him up again.

Which page of the manual is it?

R-27R/ER can have breaks in target irradiation, and some documents about MiG-29 make it seem that the illumination is kept on until the missile runs out of battery (60 s). There are manuals saying that even in scan mode the missile can guide to the target after the STT lock was lost.

Chaff behaviour is definetly broken for Aim-120. The chance of going for a chaff is almost 0 right now.

I noticed with SNP that sometimes targets will only show up for a splitsecond after each radar cycle. But when I go to the normal observe mode I see them perfectly fine.

Other players reported 120C CCM improved from 0.1 to 0.04, and 120B CCM improved from 0.2 to 0.06. Out of curiosity, could you tell me the minimum radial closure speed of the R-27R/ER in DCS?

That is a nice improvement! But when chaffs are used, is there still a chance for the missile to start tracking the decoy and guide towards it? Or will it also just start flying straight? Have the minimum radial velocities for the 120 changed with the recent updates? What were the previous values?

Where do we know from that SNP only works in PPS/ZPS, but not in AVT?

Is it the same for 120B and 120C?

In close range the 120 is no longer notchable? Countermeassure resistance was really not changed? Maneuvers that used to work by chaffing the missile no longer work after yesterdays update. So something must have definetly changed, or it is a bug (like the Aim-7 that was unchaffable for a while).

It appears that Aim-120 no longer see chaffs. Even with slow speed flying close to the notch and close to the ground below the missile they never go for the chaff. Good to see that ED made it possible to squeeze a high performance active phased array into the Aim-120 series. And because cockpit lights are broken we are not even able to tell where the missile is coming from in our SPO-15 equiped aircraft. It is beeping, but the lamps are not glowing. And obviously the Fox1 chaff bug still has not been fixed.

Thank you!

Still not fixed on latest OB, I have attached a track. I fire 6 R-27ER, unlock, and as soon as the radar is OFF they turn into a chaff released earlier. sahr chaffbug not fixed.trk

Range did increase mainly due to the new lofting. Someone wrote that at high altitudes the resistance of the atmosphere is to low in DCS, will there be a change? Lofting gives insane range improvements right now. What I like is that the Aim-120B without loft fits quite well into the russian Aim-120B estimation chart, only that it has lots of excess speed or energy during tailchase scenarios at the given ranges. R-27 is almost stalling at the ranges from their graphs.
