The pun is strong with this one

I just started playing DCS and I wanted to thank you for this very well done video. It explained even more than I expected.

I misread this as "DCS Nothing Tutorial" and thought "What, is it just gonna be a video of flying around with no speech?"

Absolutely fantastic video, you finally made me understand the principles of notching and how to perform it... no one dared to explain it so well as you did, man. Thanks

The speed loss is due to how missiles work, when fired it gets a kick up to high speed (mach 2-3 or something) by the rocket motor, but then it's flying completely ballistic ally (i.e. has no way to gain more energy), however the on board computers are continuously calculating the most efficient route to the target to ensure it conserves that precious energy. As soon as you notch and the missile looses lock it just flies in a straight glide path since it's got no other guidance commands, this means that the energy loss that's always going on due to friction is being completely wasted at this point since it's not getting the missile any closer to hitting you, on top of that it puts the missile in a bad position relative to you so that upon re-acquisition it has to make a high energy manoeuvre to get back onto an intercept path with you, this wastes even more energy and ultimately means there just isn't enough energy to chase you through any energy manoeuvres you may pull after that.

Ya I realize a lot of that, but if you watch, the re-acquisition occurs and the missile barely has to maneuver, yet it's energy is halved. I havent investigated this much further, but it looks to me like the energy loss occurs before the re-acquisition as well.

Yeah, I suppose you would have to watch the missile itself to tell. It's also possible that the missile made some kind of high energy pull but sustained it for only the briefest of periods such that tac view didn't register a large enough change to be noticeable.....

Ya this is actually something a friend of mine was discussing, he said he has observed this himself within DCS external views, I just never happened to look myself.

So here we are in 2020 and I wanted to let people know, these missions he has in the description are still there and still work great. I’m trying to learn how to do this using the Hornet and then I saw this video again. Downloaded, changed the aircraft to the Hornet and instant training. Now I’m going to go through your videos to see what other missions exist because they are very helpful. Thank you very much for making this some three years ago.

This is one of the best vids on the topic of notching. I had learned a great deal. Thanks for sharing

this was the most succinct and useful video ive found to date about dcs, regarding air to air combat. Top notch *thumbs up!*

Dude, thanks for this and the missions. New to DCS, your videos are straight what I needed.

Amazing Tutorial, thanks a lot ... very clever use of split screen along with tacview, it really helps to visualize what you are trying to acomplish when manouvering your plane.

Most awesome simulator video I've seen in a while, demonstrating a principle I'd never heard about before. Yeah, I'm getting DCS!

Excellent video. I had read the mudmover guide, but your video helped me tremendously. In your video on F-Pole/Cranking the turn to 90 would break your own radar - I assume the initial 'notch' but then then 'crank' works here as well. Thanks again, these two videos are very helpful and well explainated!

Even though I understand this concept this video was very helpful made me relieved the importance of tacview

Really great video! Thanks for doing this, learnt alot. So basically you can use crank or notch to scrub missiles and lose their lock.

This is awesome. Made a very complex subject easy to understand.

one of the best tutorials about notching!

Awesome video about notching and the use of chaff - thanks!

I love this kind of stuff... makes you feel like such a bad ass when you get good at it.

These are an excellent primer for a newbie like me, thanks a lot for putting these together!

Super helpful video! As a helo guy who would like to figure out the fast movers, this really turned on a light bulb. Cheers!

Great video, very useful even after 5 years, i am just getting into DCS

Outstanding video!! Seen from both sides. Live these types of videos.

Thanks for the great videoJabbers, new dcs player here. after numerous fails I have finally managed to notch both missiles with the Su27. Some guesswork involved in figuring out when the f15 is firing. After I did it, I was like “oh crap now I have to dogfight” onwards to the next challenge!

Great training video. Taught me a lot, thanks!

Jabbers; Thank you so much for this informational video and files. Much appreciated. Keep up the good work!

Great video!!! been trying to figure out how to notch and you nailed it!!! Thanks

Awesome dude! Very well explained, like explaining it to a 5 years old child! More of these please! You got a new sub!

Outstanding tutorial. Thank you!

Great explanation and great video!

This was an amazing video my friend! I thank you a lot! It was immensely pleasant to follow. Structure was on point and you got some real skills in explaining more complicated topics. I really liked the splitscreen Tacview/Ingame approach. You helped me to get a better grasp on how BVR geometry works. I've read about all this stuff in different documents and posts from other community members, but what made this so incredibly helpful for me was the visualization of it. It is much easier to learn and understand if you can SEE what is happening instead of imagining it. You got my sub in hope to see more of this awesome content!

So awesome video, showing basically what you need to know. As pilot of Su27 in DCS myself I confirm that everything in this video is true except when you are playing vs real player the fact is that F15 pilots like to shot salvo of Aim120 and to run away from dogfights so harder to avoid and harder to catch and kill F15 on 45000ft with lots of speed going RTB.

Great work!! Awesome video!!!

Thanks for a great tutorial. Really helpful. :-)

Ok, now I finally understood that i have to go 90 degrees left or right, thanks :)

Still gold after 5,5 years!

Frequencies don't change, but wavelengths... A subtle, but major difference!

GREAT tutorial!!

Reason why the missile get slow fast, is that the most effective flight path for the missile is to fly streight in the same direction.. When the missile turn a little or "allot" then it will loose airspeed due to air recistance and the more time a missile change course during flight the shorter the range of the missile and the slower it get it cannot regain the same "high" launch speed.... Its a little bit like climbing up the ladder.. In the start its easy and goes fast, but after some time you become tired ;-) The same goes if SAM's are firing at you.. They see you as 1 target in the air, and then they fire a supersonic missile that are aimed at that 1 possition in the sky. The missile fly so fast i the start that just a slight change in direction will make it loose energy, and distance. So example if you fly at 10.000 feet and the sam fires at you, and you start to dive. Then you are forcing this very fast missile to to a sharp turn to stay on target = loosing speed and range. All in all missiles are about Energy and making them change direction to loose airspeed and distance ;-)

thank you jabbers. very very good video

15:00 ... what I think is happening the missile is going from a lead pursuit to a direct pursuit in order to scan the airspace around your "last known location". By then the 120 has burnt through most of its energy and the sudden turn it does kills even more of it.

Keep it up! I finally know how to defeat an AMRAAM!

Big like ! This should be tought in schools

Nice video, thank you.

May I note that, the frequency does not change but the wave length changes(Doppler effect)

Beautiful

the circus music was spot on :D

awesome nice explanation

Watched this video again. And noticed your question about why it looses a ton of speed when re-acquiring. What i suspect is that it looses that speed cause it try's to correct it's flight path after re-acquiring. At that moment it's not flying the ideal flight path so it has to adjust with a hard to to it's expected point of impact. And at those ranges every turn you make is a hard turn for the missile.

@Jabbers

It actually pulls like 13g the instant it breaks lock.

Great video and great details man. Thx! Now, about the 120C..., yes, it was probably about right compared to reality (although it's all classified) as it made more sense that it can't be invincible as it also uses the same pulse-doppler radar combination and is still not an "alien" tech that won't lose you into clutter and terrain masking (this giving both the pulse and doppler modes a hard time to stay on the target), so yeah, it wasn't invincible back then when you made the video, but now, in 2.7, the 120C is almost virtually insensitive to notching and chaffing. The 120B, from my opinion, behaves more expected, while the 120C is kind of too good to be true, at least from what I believe! I mean, yes, in reality, they have upgraded the 120C-5 and -7 to be more effective in keeping a radar locked on a target in difficult conditions such as ground (clutter) and beaming, but from my opinion, it's kind of too effective in DCS.

In the last scenario for the F-15 is more complex and have to launch chaff and flares, because at this distance, the Su-27 pilots always shot an ER to make you notch and an ET after, while the ER goes nowhere, for the ET your notch is a torch in the night! :D Thats why in DCS the ET is the best russian missile in medium range. Anyway is a cool video! thanks!

Well, that really applies to all missiles in DCS. The 120 should have a much larger range as well.

I see that you mentioned that the M2000 has much more drag now. In the past, I had read that Razbam's flight model was quite unrealistic in regards to energy loss during maneuvers for a delta wing plane. Was this information correct, and if so can I assume that this has now been fixed? By the way, I really enjoyed this video and the F-Pole one and I would be glad to see more like them

Great Video!

Damn I'm hungry. I thought I heard you say you were going to talk about nachos and I got all excited.

Great video, and thanks for the mission files. Can you explain a bit how do you transition from fighting the missiles to dog-fighting the plane? This is the phase I have the most problems with. After the second missile I know that the second plane is close to my left (or right), but going from there to actually spot the airplane is very difficult. Sometimes I see the missile trail and the RWR also helps but it's still mostly a matter of luck. Is there a better way?

@Jabbers

7 жыл бұрын

I think it's mostly just experience, if you know where they are, and you were defensive, you know the angle and that they are probably higher than you, so switch to vertical scan and see if you can find them. you can even try bore sight as well. Spoting targets takes practice, but even in this video I lost track a couple times and had to check RWR and continuously scan visually. When I know the bandit direction I try for a head on merge, generally if I don't see them head on, I watch the RWR and when they disappear I know they passed me, so quick turn (not to quick, don't wanna lose that energy) and start scanning visually behind and to the direction im turning. Practice Practice Practice :) SA is hard.

Great video. You might want to have mentioned that the missiles burn though there propellant fast and once they hit max speed they are flying on energy. Causing the missile to make hard turns and gain altitude cause it to run out of energy faster and will cause it to miss the target.

dixxyplays yup this is true. Turn and burn is always an option, he was over 6 miles away so I probably would have been fine burning to the closest friendly or back to safety

As a M2000C pilot if I'm scanning 10 miles I'm front of me will another aircraft pick it up on RWR from 60 miles away?

@Jabbers

If he is inside your cone probably, just because you are scanning 10 miles doesnt mean your radar pulse isnt going farther.

this rocket use a one equation be given to the rocket before it gone but it disconnect with the RWR to give it a edited equation to change it's bearing and to change speed according to the equations that came of RWR ,

Very good explanation. I like your video a lot. But i like to note one thing. In DCS you can notch with a sky background and when flying higher then the radar. I don't know if this is realistic or that some other factors are into play here. Any thoughts on this?

hmm after the spectral discussion I would have guessed that "notch" would refer to getting your plane into the spectral notch filter applied to the radar return to filter out the ground. Amounts to the same things and I don't know how you'd check but it might be interesting to explore if that is the real origin of the term.

@Jabbers

5 жыл бұрын

You are correct

So, against active radar missiles you notch the missile. Against missile relying on datalink from the plane or semi-active missiles which are nearly parallel to the launching plane's radar beam, you notch the plane. I'm wondering about semi-active missiles when there is a significant angle difference between the launching plane (and its illuminating radar) and the missile that receives the bounced echo. If the missile is semi-active, there may be a significant angle to the bounce from the plane to the target and the target to the missile and I'm not sure how that would affect using the Doppler effect to filter the returns with MTI.

@Jabbers

7 жыл бұрын

There are 2 types of radar missiles. Semi-Active: Requires the planes radar for guidance. Active: Initially requires the planes radar for guidance but at some point goes "Pitbull" and activates it's own radar and guides itself. In DCS the following applies: For Semi-Active missiles you notch the planes radar, this requires watching your own RWR to find the position of the enemy plane and put your beam to it. For Active missiles you can notch the planes radar initially, however, when the missile goes Pitbull it is probably going to aquire you as a target, so you have to notch the missile at this point. Something to keep in mind is that if you are notched to the missile when it goes active, and there is another plane around, it may go pitbull on the wrong target. In real life, your guess is as good as mine, Im not 100% sure how the inner workings of it all work, for all i know the radar on the plane that fired the missile is just sending position updates rather then the missile processing the doppler pulse itself. Great question though, sorry I couldnt answer it.

@eddievhfan1984

5 жыл бұрын

Well, with semi-active, the illuminating RADAR is practically in continuous-wave mode to steer the missile, so as long as it gets a reflection of *something* it'll track it. There, chaff gets quite effective, as STT can be quite easy to screw with, depending on what kind of clutter filtering is involved. Regarding MTI, I figured that didn't really work on a CW emitting RADAR, since there's no sampled pulse to compare against itself.

Notch actually refers to the notch filter used in RADARs.

nice video. thanks a lot. just a quick question though. how do you react when bandit launches an 120 and just before it goes pitbull he launches on more. In that case you have to noch the pitbull 120 and also the bandits radar right?

Gotta take that one 1 threat at a time. Most dangerous threat is the closest missile, chances are you won't know about the 2nd missile anyway since it hasn't gone pit bull. So deal with the first missile and then the 2nd. If you have someone spamraamming you, your best bet is to find some terrain and out it between you and the missile. Or splits and head for the hills.

Jabbers thanks for the heads up. will try it next time I get in a situation like this.

I don't know if you remember "Notcher" from Iron Eagle. Yea.

Just to note, not all radars are pulse-doppler radars and therefore cannot be fooled by notching. I'm not aware of any modern aircraft that use any other systems due to ground clutter, but few surface-based missiles use it (eg, the fire control radar on the 9K37 Buk series is a monopulse radar).
