Your notch is defeating the missile not the chaff. You also change your altitude to break the IOG guidance phase. If you had done those steps without chaff there is a chance you defeat the missile
Try that in a disadvantageous position being ambushed, short range shots and BOL chaff is not as effective.
He notched a missile the notch and altitude changes are what defeated the missile. When you notch the missile radar switches to into IOG mode as it cannot find you, it heads to where it thinks you are. As long as you stay perfectly in the notch and make changes altitude changes the missile will in many cases fail to reaqcuire.
In game we use chaff to guarantee the missile does not reacquire.
My point was that worked great because of the notch, now how effective is BOL chaff at avoiding an R-27ER launched close range? Or a MICA when you do not have time to get into the perfect notch?
Only if the missile seeker can see him though, as we don’t have DL after a certain point the missile seeker would have to acquire him when he is already in the notch. If that was an R-27ER he likely doesn’t defeat it as he would have to notch the aircraft Radar. I’m not saying you don’t need chaff I’m suggesting he performed the perfect defensive manoeuvres.
A better test would be to enter the notch fly straight and level and aggressively chaff and compare that with BOL chaff and Large chaff. Then while the missile may still reacquire we can see how many in comparison it took and how many times the missiles seeker bit on the chaff using the sensor view mode.
I have said that chaff is needed but the test was perfect conditions.
the steps taken were the correct ones and it doesn’t really prove BOL chaff is good or bad.
Defending against any ARH or SARH in the Tornado Gr4 is trivial compared to the F3. They have the same RWR, they have basically the same FM (if anything the F3 is better). The only meaningful difference between them is one has BOL and the other has large calibre chaff.
there were multiple missiles fired and some of them were looking up, meaning that they were in LPRF and will be able to track you even in a perfect notch
I think you are confused. Chaff aren’t the most important to defeat missiles. The most important aspect remains notching. Chaff are only useful when the missile (or the DL from the plane) switches from pulse Doppler to regular tracking (such as in the video above when the missile sees clear sky behind the plane). Then, when chaffing, the missile switches to IOG (whatever the size of the chaff), which is when you need to pull outside of its IOG vector
Do you think that chaff is just supposed to permanently defeat the missile regardless of aspect? The first missile is launched at 18km which is within visual range and from front aspect. Do you not understand how this works? The whole point of chaff is to temporarily distract it and move out of its field of view. I am showing you exactly how to do it and how it is repeatable. Every missile in game can be defended against this way; the only one that is a little harder is MICA due to much narrower notch gate and higher closing speed.
Defeating missiles with notch up is more advantageous when they are closer because their search zone to reacquire is smaller. This technique is simple enough that I could probably teach morvran how to do it and practice it in a 20 minute long discord call.
It’s alright on the gripen with the comparatively cold running RM12, but in a harrier, or with the portable star that is typhoon engines it loses that effectiveness.
This and this is the reason why the BOL nerf on chaff hits particularly hard. While notching is the main factor, worse chaff means you need a better notch to be successful. In aircraft with large calibre chaff I can generally just “vaguely notch” and hit the chaff wall and get away with it, but with BOLs it’s a bit (lot) more careful, albeit quite easy to achieve with the typhoon’s handling and the DASS.
