Excellent use of diagrams followed by in-cockpit examples to illustrate how to apply these principles tactically--great stuff. And I greatly appreciate the updated terminology regarding turn rate. One thing I would note for your viewers who fly jet sims is that while the speed for the best sustained turn rate for the BF-109 happened to be at the lift limit and coincide with the speed for minimum sustainable radius, this is not always the case. This may even be generally true for prop fighters, for which I have no data, but is not for jets. For jets the minimum sustainable radius will be at the lift limit, but the maximum sustainable rate will usually be a much higher speed, and depending on conditions can even be higher than corner speed. The Ps=0 plot for a jet typically has its peak much farther to the right than the BF-109 curve. This translates into a need to restrain your pull and perhaps even keep your speed above corner in some cases if you want best sustained rate.
No worries Gort, I've wanted to revise this one for a while but never had the proper time to finish my EM spreadsheet how I wanted. I took unpaid leave this month from my airline so I've had time to finish it and it's good to go now haha You're correct regarding the jet info, so thanks for sharing it. As you can understand I wanted to just explain a diagram with a single example many people would be familiar with. The great thing about my spreadsheet is I can create diagrams for any airplane if I have the data for it now. A common problem you see with a lot of people in props and jets is they just pull and pull and pull trying to turn faster but that doesn't always work out, so hopefully this helps with for some people understanding this a little better. I'm planning on going into more depth with this stuff when I can get data comparisons between props and include some jet examples in there too, but for now this illustrates the basic concept to build off in the future.
@Gort I've wondered at the applicability of haptic feedback for sim pilots. Something that squeezes gently on your legs, perhaps, emulating a g-suit inflating, that gives you feedback on how many G's you are pulling? Tunable by the user for their own desired "feel"?
@@aurorastarfury That might provide better G awareness and I'd like to try it! I would also like to see someone make a seat cushion that would vibrate with varying frequency and amplitude to communicate airframe buffet. You can feel a lot of nuance in buffet that simply shaking the visual in the game is unable to communicate. Trying to make these sims too purely realistic makes them unrealistic in some ways. I want an accurate model, but you need something to replace the somatic sense your body provides if you want to fly that model like you would the real airplane. Perhaps a tone that indicates AOA or G. Purists will say the real airplane doesn't have that, but he real airplane has G forces and buffet that you use when you max perform it.
Thanks Greg, I was hoping you would like it! I've spent so much time working on my EM generator that isn't apparent to most because all you see is a picture...but it's in a great place now to illustrate this concept a little more in the future :-)

Great explanatory video, I'm afraid I've had to learn this (as much of it as I have) by hard, bitter experience, it's good to see the science behind it. It does beg the questions; how the various aeroplanes perform vs each other and if they're well modelled in the game. Thanks.

@@RequiemsACTL I somewhat understand the basics but trying to apply it in practice when playing all the different VVS and RAF planes makes me come back to the CEM tutorials. maybe, just maybe some day i can fly bf-109 without EM automation!
This video is loaded with incredible information. I really want to try making a chart like this in excel for the f/a 18c in DCS for my squad. Is there any chance in hell you could make a tutorial on creating this chart? How to gather the data, what math to use and how to plot it in excel. Love all your videos mate, thank you for so much free education. Cheers!
Very nice presentation! If I understand it correct the SL-line shown around 04.30 is also representing a max G-limit of about 3.3 at any speed if you want to maintain level flight? Comparing it to the level turn data around 01.00 that would indicate a bank angle no more than sligtly above 70 degrees.
@@RequiemsACTL I also found it highly interesting what you say from 06.50 that WW2-planes can´t sustain corner speed in level flight because of limitations in thrust. Didn´t know that. Also see that the Level Turn Data at the beginning is purely theoretical and not specific for the 109 F4. Especially the last rows for 270 (exceeds the F4:s lift limit) and 450 (too little engine power). Got a bit confused there at first :-). The good thing about your videos is they lend themeselves to be watched several times.
hello. Thank for these playlist videos. I am playing DCS WORLD and I want to go deeper in dogfight and learn about it. Your videos help me a lot to understand what is going on during a dogfight. Also I am wondering how to create a template for a " EM diagrams" with excel. I have collected data but I am not able to put it on a diagram like yours (more than two axes). I search on internet but I find nothing about it. Can you help me if it's not too complicated ?
Excellent video. Now with the G-indicator in IL-2:GB we can actually try and follow these methods directly in the game. Is similar data available for other planes in the simulation? Thanks.
Thanks Meph, the problem is...testing takes time and it's not something I always have a lot of. I asked people to help with testing but didn't get any takers so it's either A. People don't care about this data, or B. They don't know how useful it can be. I'm working on a video that will hopefully solve problem B and maybe encourage people to get data for their prefered airplane so I can create these diagrams for more airplanes.
I am disappointed that DCS does not provide some of those speed vs altitude data for corner speed or max sustained turn etc. That would be kinda useful for a fighter. /s
I’ve been looking for this information for a LONG time. They didn’t publish these speeds back in the 1940’s I guess. I’ve googled the s#$@ out of them. Thanks for running the charts Requiem. Now, any chance you could do this for some of the other popular airplanes??? If not, I’ll try it myself but I AM a history major...........
I've already got charts for basically all the airplanes done already (with comparisons), but I don't have sustained turn data for them. I asked in the Il-2 forum for help testing the airplanes for it but basically had no takers. I've even created another one for DCS airplanes to test those too.
Thanks, I've used WWII planes to demo BFM principles as their speed is a good compromise to keep the airplanes within a decent visual range of each other without slowing down the progression of a fight/maneuvering too much
Great video, as always! How could I obtain the data necessary to build an EM chart for a plane? I know how to work out the turn rate at various speeds, and the maximum airspeed, but what about lift limits at various speeds? Thanks!
I'm very new to IL-2 and watching lots of vids like this one to learn. I noticed that most videos use the BF 109 for demonstration. Is there a reason for this or is it just a coincedence?
No reason really. Just for consistency to demonstrate the principles. Could have used different airplanes every time from props to jets but that would have been confusing to people trying to learn this material for the first time.
What ACM is all about? Is It about tactics for just when you fighting against multiple opponents, been either 1 vs many or many vs many or something else?
At the end, I didnt got the diference between the in plane and out of plane turning room, because it seems to bem the exactly same manoever, but to diferent sides each time. Could you clarify what am i missing?
Just think of it in relation to how both your wings line up with each other. If they're aligned (parallel) with each other you're maneuvering in the same plane of motion. If your wings are not aligned (towards being perpendicular) with each other then you'll end maneuvering in different planes of motion.
The blue line (sustained turn) is related to thrust because at any point along that line thrust = drag and there is no more acceleration in the turn at a particular G force. Since the power is at maximum it can't go any higher, but these lines vary between airplanes so that's why engine power plays a part as one of many factors in aircraft performance
Does anyone know what is being used in this video to playback the flights, and show the trailing path? I know how to record and playback flights in IL-2 Sturmovik, but can I visualize the playback with the trails, or is that a third party plug-in?
+RequiemBoS *Thanks for a simplified explanation of how turn factors affect air-to-air.* Had the Kriegsmarine (DEU) put a carrier into commission, the U. S. Navy would have two Fighting aircraft available to obliterate the Bayerische Flugzeugwerke (DEU) Bf 109H-4 and seize the air superiority that the Curtiss SB2C and Eastern/GM TBM would have needed to attack and sink the German carrier battle group: The Chance Vought F4U-1D and the Grumman F6F-4, both of which had a decisive performance advantage over the '109's Daimler-Benz (DEU) 605 inverted V-twelve with the mighty Pratt & Whitney (USA) SGR-2800 radial-eighteen. "Valencia's Mowing Machine," applicable to USN VF's with F4U and F6F, made extensive use of the vertical for engaged division tactics.
Maybe this a stupid question but regarding the corner speed and that ww2 can’t sustain it in level. When turning can’t I just loosen the pressure on the stick to maintain wanted speed (270 in this case)?
No, it's not a stupid question at all. Corner airspeed is not just considering airspeed by itself, but is the airspeed you can apply maximum G force at to achieve your maximum turn rate (The 270 km/hr is completely separate because it's the best sustained turn rate for the 109 in this case). If you're loosening the pressure on the stick, you're relaxing how much G force you're applying so this means although you may be as fast as the corner airspeed is you're not actually applying enough G to maximise your turn rate. However, because you are at corner airspeed this means you have the potential to maximise your turn rate (however long that may be for). Think of corner airspeed as a sign of where your airplane can max perform basically. WWII airplanes don't have the thrust needed to maintain corner airspeed when they are maximising turn rate in a level turn unless they are sacrificing energy (in the form of altitude) to stay there, so that's why you end up bleeding energy in a level turn (in the form of airspeed) and should aim to slow around the best sustained turn airspeed if you're in a prolonged turn rate fight.
@@RequiemsACTL Somebody claimed that 270 km/h is also the "ideal climbing speed" for Bf 109. Are they confusing these numbers or is there a relationship between those two factors that makes them both land at 270 km/h?
@@LosBerkos No I don't think they're confusing the numbers. I believe that 270 km/hr is the best rate of climb for a Bf 109 as well. It may be that your simply producing the optimal amount of lift for the drag produced at the AoA required in the two different scenarios
@@RequiemsACTL I've always been tempted to make EM charts for a bunch of aircraft. Do you happen to know if anyone has done this already? My one constraint (with covid) is that I'm stuck on my work laptop and it runs the sim at less than realtime, so tacview is a necessity. Makes it awkward though as I'd rather just review footage and time off that.
I don't think anyone has. Now that my spreadsheet is complete I can start pumping them out relatively easy, but I need test data for sustained turn stuff, so I'm making a post on the forums about it at the moment.
@@McDewgout I will. I did make an earlier post but didn't get anyone to help me with them. I've made a video discussing EM theory that seemed to have good interest so maybe I'll get some takers next time around

If you're loosening the pressure on the stick, you're relaxing how much G force you're applying so this means although you may be as fast as the corner airspeed is you're not actually applying enough G to maximise your turn rate. However, because you are at corner airspeed this means you have the potential to maximise your turn rate (however long that may be for). Think of corner airspeed as a sign of where your airplane can max perform basically.
WWII airplanes don't have the thrust needed to maintain corner airspeed when they are maximising turn rate in a level turn unless they are sacrificing energy (in the form of altitude) to stay there, so that's why you end up bleeding energy in a level turn (in the form of airspeed) and should aim to slow around the best sustained turn airspeed if you're in a prolonged turn rate fight.
@@RequiemsACTL You understood my point and answered very well Thank You very much!
@@RequiemsACTL Somebody claimed that 270 km/h is also the "ideal climbing speed" for Bf 109. Are they confusing these numbers or is there a relationship between those two factors that makes them both land at 270 km/h?
@@LosBerkos No I don't think they're confusing the numbers. I believe that 270 km/hr is the best rate of climb for a Bf 109 as well. It may be that your simply producing the optimal amount of lift for the drag produced at the AoA required in the two different scenarios
How did you derive the sustained turn for the EM graphs?
Multiple timed turns at various constant airspeeds
@@RequiemsACTL I've always been tempted to make EM charts for a bunch of aircraft. Do you happen to know if anyone has done this already?
My one constraint (with covid) is that I'm stuck on my work laptop and it runs the sim at less than realtime, so tacview is a necessity. Makes it awkward though as I'd rather just review footage and time off that.
I don't think anyone has. Now that my spreadsheet is complete I can start pumping them out relatively easy, but I need test data for sustained turn stuff, so I'm making a post on the forums about it at the moment.
@@RequiemsACTL Could you please drop a link to the aforementioned forum post where you intend to post these graphs?
@@McDewgout I will. I did make an earlier post but didn't get anyone to help me with them. I've made a video discussing EM theory that seemed to have good interest so maybe I'll get some takers next time around

What?!
Well, if I watch this every two months (like I do) then EVENTUALLY I'll get it all!
It just takes time and practice, but one day things will "click"
What game is this??
Il-2 great battles
For the love of God, never use capital M for meters. It's always m. Always.
