Il2 Update 4.502 released
By 76.IAP-Blackbird,
Update 4.502
Attention Pilots! On this chilly Autumn day, we’re releasing a large update to IL-2 Sturmovik - update 4.502 is here! The star of this update is the new Hurricane Mk.II Collector Plane. This plane has the most modifications in our sim and with a wide range of weapon loadouts available this makes it 5 aircraft in 1. You get several variants including the IIa, IIb, IIc, IId and the one with the Soviet armament. The famous Dust Filter and Merlin XX engine with +14lb boost are also available. On top of all that, you can use the new bird in the Career mode right away - we added it to the Battle of Moscow and the Battle of Stalingrad careers. In addition to the Hurricane we have added the legendary С-47А "Skytrain" transport plane for the Battle of Normandy. The C-47 is AI only, but adds a new dimension to our missions and variety of Allied aircraft you will encounter in the sky. It is also great for mission makers who want to make supply runs an integral part of their battle. And finally, Battle of Moscow players receive new 4K quality skins for the Bf-110 E-2 thanks to our talented friend Martin =ICDP= Catney. On the technical front we have added a new and more realistic G-load physiology modeling system. This work was described in great detail in our Developer Diary #263. Additionally, a lot of work was done on all the aspects of the ground battles, significantly improving the quality and realism of Tank Crew engagements. There are many improvements to the pilot AI as well in this update. And finally, long-awaited Career mode improvements are finally starting to arrive.

Il2 DD Update Dev Blog 264 "C-47 & Hurricane"
By 76.IAP-Blackbird,
Dear Friends,
It's the middle of Autumn already and the work on the project progresses well. For instance, the AI-controlled transport plane C-47A Skytrain (Dakota) for Battle of Normandy is almost ready and you'll get it in the next update. This WWII veteran served in air forces and civilian air fleets of many countries for several decades - one of the iconic symbols of the piston era of aviation. These aircraft played a tremendous role in the Battle of Normandy, dropping paratroopers, supplies and towing assault gliders. This legend will be finally reconstructed in our project, even if it is an AI only aircraft for now. Later on, when we complete another stage of the Career mode improvements, it will be used in this mode for transporting cargo loads, airdropping paratroopers and parachute supply containers for the troops on the front-lines. At the moment the new paratrooper model and its integration in the Career mode are not yet ready for Early Access, so this aircraft will be available in QMB and community-created custom missions as an ally or enemy loaded with cargo or parachute supply containers.
The second hero of the day is the upcoming Collector Plane - the British Hawker Hurricane Mk.II fighter. This legendary early war aircraft saw much action in the Battle of Britain and later on the Eastern Front with the Red Army Air Force via the lend-lease program. This fighter actively participated in the Battle of Moscow and Battle of Stalingrad and the owners of this Collector Plane will be able to use it in the Battle of Moscow and Battle of Stalingrad careers in the coming update. There were many different modifications of this plane, the most interesting ones will be available in our sim:
Hurricane Mk.IIa - default model with eight Browning .303 MGs;
Hurricane Mk.IIb - modification with twelve (!) Browning .303 MGs;
Hurricane Mk.IIc - modification with four 20mm Hispano Mk.II guns;
Hurricane Mk.IId - two assault modifications with two Browning .303 MGs and two 40mm Vickers S Class guns, with or without additional armor plates;
Hurricane Mk.II Soviet - modification armed with Soviet bombs, unguided rockets, two 12.7mm UBK MGs and two 20mm ShVAK cannons;
In addition, either of the modifications listed above can be equipped with a Merlin engine with an additional boost, air cleaner for dusty conditions and rear-view mirror.
The work on Tank Crew is continuing as well. The coming update will include very important changes for ground vehicle AI, both detailed and simpler modeled vehicles, making the AI gunner actions more realistic. To hit a target at a distance, they will usually bracket a target with gunfire as they find the proper range. Spotting a target to the side of the current aiming line will require more time the more distant it is. Both of these actions will depend on the AI proficiency level set in the mission. The AI gunner will also behave more naturally when the target is destroyed or no longer visible - it won't rotate the turret to the default position immediately, but will wait for some time, looking for more targets in the same general direction. Many smaller improvements and changes will be added as well, as we prepare Tank Crew for its official release.
Enjoy!

Salute pilots!
It’s been a year since we introduced a detailed human physiology model in our simulator. The model which takes into account the limits of human’s G-load tolerance, as well as a number of other factors affecting pilots in flight. This, of course, immediately and greatly changed the dynamics of air battles. They became much more realistic. After all, now, when performing an attack or a defensive maneuver, you have to take into account the fact that a living person with his natural physiological capabilities and limitations is sitting in the cockpit. And that any pilot, of course, gets tired of constantly maneuvering at high Gs. And in the end, there comes a moment when he just needs time to catch his breath and recover. We were interested in your opinion Over the past year, we have read a lot of your comments on the forums and collected a lot of feedback about this model. We have seen that this new and exciting aspect of dogfight has been very warmly received by the bulk of our community, and it's encouraging. While another part of the players asked us to make some changes to this model. In order to understand the situation, a month and a half ago we conducted a poll among players on the .com and .ru forums. What did the poll show? The poll results showed that 60% of players are quite happy with the current model (494 out of 821 unique users on both forums, excluding the extra 31 votes of those who voted twice, i.e. on two forums). And 40% of players would like us to make adjustments to this model. I had carefully read all your comments on the polls. In general, there were more players satisfied with the model on the Western forum, so I conducted a more detailed analysis of that thread and found that 63 out of 381 Western users who chose option 1 (“leave everything as it is”), nevertheless, in comments have written a number of requests for changes in the model. Thus, it became clear to us that the community was divided in opinions approximately 52/48. This means that we cannot leave this situation unattended and we need to think carefully about what can be improved in our model. Collecting new scientific data Over the course of this year, thanks a lot to you, our community, we have collected a large amount of new data from the field of aviation medicine and human physiology under extreme stress conditions (I would like to express special thanks to comrade @Floppy_Sock for the materials he found). This allowed us to take a fresh look at our physiology model and find ways to improve it. For example, a year ago, in my work on a physiology model, I relied mainly on the well-known monograph of the Russian scientist, professor, doctor of technical sciences Boris Abramovich Rabinovich “Human safety during acceleration (biomechanical analysis)”, 2007, where while talking about the duration of the G-loads a human can sustain, he refers to the famous article by Anne M. Stoll, "Human tolerance to positive G as determined by the physiological endpoints." ), published in The Journal of aviation medicine in 1956. This article provides a graph of time to loss of consciousness versus G-load. It is compiled on the basis of the results of 40 experiments,13 of which ended in loss of consciousness by attendants. However, recently we learned that in 2013 there was another article published on the BioMed Central portal in the Extreme Physiology & Medicine section: “The +Gz-induced loss of consciousness curve ”. Its authors, Typ Whinnery & Estrella M Forster, prove there the fallacy of the conclusions from the article of 1956, relying on much broader statistics: now they had already 888 cases of loss of consciousness by testees. These statistics were collected from 1978 to 1992 at a number of US research centers (USAF School of Aerospace Medicine, Brooks AFB, Texas and the Naval Air Warfare Center, Warminster, Pennsylvania). In particular, in their article Tip Whinnery and Estrella M. Foster argue that at high +Gz (that is, acting on the pilot in the "eyeballs down" direction), up to +11.7G, the subjects never lose consciousness earlier than 5 seconds after the start of acceleration, and on average statistically - only after 9 seconds after it. While in our current model, built on the basis of data from the sources published above, loss of consciousness occurs within 3-5 seconds at acceleration of more than 6-7G. Authors of the study explain this difference by the presence of a certain “functional buffer” of the brain, which prolongs the activity of the brain for a few seconds after the arterial systolic pressure at the level of the eyes (brain) drops to zero under the influence of extremely high Gs. In addition, many players asked us to reconsider the pilot's tolerance to large negative Gs (assuming that the deteriorating effect of negative Gs should be more pronounced). They also asked us to implement the so-called push-pull effect (PPE), which manifests itself in a noticeable and very dangerous short-term decrease in the +G tolerance immediately after a negative one. Many aviation accidents on maneuverable aircraft are associated with this notorious effect. Over the past year, we managed to find scientific materials about this effect, too: for example, an article published in 2011 on the scientific, technical and medical portal Springer, co-authored by a number of Chinese scientists “A centrifuge simulated push-pull manoeuvre with subsequent reduced + Gz tolerance ”. This and over three dozen other publications, NASA reports, scientific dissertations, and unique test materials that we have collected, gave us a large amount of numbers that we could rely on with greater confidence. And the need to simulate the above-mentioned phenomena presented me with the fact that it is not just about readjusting the coefficients of the current model. It became clear that the model would have to be built anew, with a more detailed account of all factors acting on an individual and an even more detailed simulation of physiological processes in his body. Today I am glad to tell you about the results of this work. First impressions The new pilot physiology model is currently undergoing a detailed and meticulous beta test. The first impression it invoked in our testers, and which, most likely, it will invoke in you, is “it became more forgiving”. After all, due to the appearance of the “functional buffer” of the brain, quick and short-term maneuvers at very high Gs have now become possible without immediate loss of consciousness. More details... For example, if by a one second long jerk one pulls +7-8Gs, then visual disturbances in the form of a "gray out" (which is loss of color perception) will now occur only 3.5 seconds after the beginning of acceleration. After another 1.8 seconds, the peripheral field of view (the so-called “tunnel vision”) will begin to narrow. The vision will be completely lost (“black out”) after another 2 seconds, that is, only 7.3 seconds after the start of the maneuver. And after another 1.6 seconds, G-LOC (G-induced loss of consciousness) will occur. It has also now become possible to perform, for example, a loop or a split-s with the initial and final G-loads of +5...+5.5Gs without loss of peripheral vision. But if these Gs are maintained during the maneuver for longer than 25 seconds, the “blacking out” will nevertheless begin to happen, and consciousness will be lost 32 seconds after the start of the maneuver. In general, at first you may really think that the pilot has become more resilient, and it has become easier to fight. Has it really become easier? But already after 2-3 days of “test flights” our testers found that the first impressions were somewhat optimistic. Yes, you can now actually “kink” the trajectory more sharp. Once, twice ... but you won't be able to maneuver for a long time, while constantly holding high Gs. You will have to reckon with fatigue and a decrease in the pilot's tolerance to G-forces during the battle, just as before. And just as before, you will have to plan well the trajectories of the fight, choosing the moments when to “pull” and when to let yourself catch your breath. About endurance and fatigue As I wrote above, we have collected a large amount of scientific data on a human's tolerance to +Gs and -Gs of different magnitude. Unfortunately, some of them are contradictory, and there is no one single model of the “average person” that would reliably describe our “average” endurance. In one source, you can find information that an experienced aerobatic pilot can withstand +2Gs only for 13 minutes, while in another source, you can find a figure that the + 3Gs are quite normally tolerated within an hour. At the same time, when we talk about larger Gs values, the numbers from different sources become closer to each other. But still, this subject has some field open for discussion. Therefore, the endurance of our pilot to long-term G-loads, as well as to cyclic G-loads in the new model is adjusted both taking into account reliably known data from various publications, and based on the impressions of real pilots with aerobatic experience. We have involved military pilots and pilots flying on sports aircraft in testing. They all praised the results achieved, and admit that the model reproduces their own feelings quite closely. What else I think that many players will be especially pleased with the fact that the new model now contains several interesting phenomena that have been simulated thanks to a more detailed calculation of physiological parameters. PPE For example, the push-pull effect. If you pull a high positive Gs immediately after the action of any prolonged negative Gs (of which only three to five seconds is enough), then visual impairments will come faster than usual, at noticeably less G-load. To the extent that such a maneuver can lead to an unexpected LOC. The greater the negative G was and the longer it lasted, the more noticeable this effect will be. But just a few seconds of a pause after a negative Gs is enough: the cardiovascular system will have time to adjust and will be ready again to normally sustain positive Gs. This effect is due to the fact that with a negative G, blood intensively rushes to the head, and the body reacts to this by rapid vasodilation, seeking to reduce cerebral pressure. And if, in such a state, a large positive G is immediately pulled, then the vessels will take time to narrow again and maintain the now falling blood pressure at the level of the brain. At this moment, a quick crisis comes. Warming up effect Also, thanks to the improved calculation of vascular response, the new model has a “warming up” effect. It is when the first short maneuver at high +Gs is tolerated worse than the subsequent ones. It is also related to the compensatory response of the cardiovascular system, which needs time to “warm up” in order to maintain sufficient blood pressure in the head. If you pull, for example, +6G in one-two seconds, withstand it for five seconds (this is when you will get the partial “tunnel vision” effect), then reduce to 1G, pause for five seconds, and then create the same +6G for the same five seconds again at the same rate, then in the second case there will be no “tunnel vision” effect. But the same maneuver made third in a row will again lead to a partial "tunnel vision". But this is already because of a decrease in the tolerance limit due to excessively intense load without sufficient recovery time. Backrest angle Over the past year, there were many attempts by some players to prove that there are differences in the endurance of the pilots of one or another coalition. Although the physiological model of a pilot was the same and did not depend in any way on the plane in which he was sitting. However, now in the new model of physiology, while still remaining the common model for every pilot, the peculiarities of the aircraft cockpit in which the pilot sits are taken into account. Namely, we are talking about the backrest angle. As you know, tilting the seat back significantly increases the pilot's tolerance to G-load. This is due to a decrease in the difference in hydrostatic blood pressure between the heart’s level and the head’s (eyes) level. For example, tilting the seat back by 30° increases the maximum G-load-sustaining capacity by about 15%. Many researchers also attach importance to the position of the legs. For example, the Spitfire even had two pedal positions: a lower one for normal flight and a higher one for aerobatics. It was assumed that in the elevated position of the legs, the outflow of blood from the head to the legs decreases under the action of +Gs. However, a number of experiments have shown that this effect is negligible, and, nevertheless, the angle of inclination of the pilot's upper body plays a much larger role. The new model takes this angle into account, which on all highly maneuverable aircraft in our simulator ranges from 0 ° (MC.202 series VIII) to 22.5 ° (MiG-3), averaging about 10-15° for different planes. AGS In the current physiology model the effect of the anti-G-suit (AGS) was simulated empirically, based on statistical data. In the new model, a detailed calculation of the suit’s pressurisation dynamics and the effect of this boost on the hemodynamics of the pilot's blood pressure is performed. Several mathematical models of this phenomenon can be found in scientific research, and all of them give, on average, results that are in good agreement with the tests for modern AGSs. In our new model, we used the characteristics of suits from the 40s, which gives us confidence that this aspect is now modeled even more authentically. AGSM In the scientific literature, the term "anti-g straining maneuver" (AGSM) refers to a set of special measures that a pilot applies in order to temporarily increase his tolerance to G-load. This is a special type of breathing (you are familiar, of course, with it from the current version of the simulator), as well as tension in the muscles of the legs, butt and abdominal press. A well-trained pilot who has undergone special training in a centrifuge, using AGSM, is able to increase his G-load tolerance limit by 2 to 4G! It is not easy and requires a lot of physical effort. If the AGSM is performed incorrectly, then the effectiveness of such a technique is sharply reduced. As you know, during the World War II, pilots did not undergo special training on centrifuges, and were not trained to perfectly perform AGSM as modern fighter pilots are. But even then it was known that the tension of the muscles of the press and legs together with strained breathing allows one to endure higher Gs. Taking these facts into account, the pilot in our game (just as before) performs the AGSM not “excellently”, but “somehow”. This increases his tolerance limit for prolonged G-loads from 5.5G in a relaxed position (statistics are on the chart below) to 6.7G. This is about 0.4-0.5G more than in the current model. Such a slight increase in the limit of the maximum tolerated long-term positive G-load, however, will now make it possible to maintain a g-load of +6G with a partially narrowed peripheral field of view, up to a complete loss of vision within 18 seconds. Loss of consciousness under this Gs will occur in another 2 seconds.
(all pictures are clickable) At the same time, I hasten to inform you that the annoying bug of “double breathing” (duplicate overlay sounds), which sometimes appeared in our game, will now be fixed. Visual effects I would especially like to mention that the effects of visual impairment have also been readjusted. I personally have been flying aerobatics in ultralight and light sport aircrafts for many years, but over the past year I got a new aerobatic experience, now with high G-loads on the Yak-52 sports airplane. Therefore, I now know firsthand what all phases of visual impairment look like from the beginning of the “gray out” appearance, then through a “tunnel vision” and, as a result, almost to a “blacking out”. As they say, a real picture is worth a thousand words. So now in the new model the manifestation of such effects as loss of color, “blurring”, “tunnel vision”, - very accurately correspond to what I see with my own eyes in real flights, if I perform a maneuver with a long-term 5.5 to 6Gs. Other pilots who have tested the new model also agree with this visualization. The red-eye visual effect under the influence of negative Gs, has also been slightly enhanced: Visual disorders dynamics Additionally, in our new model, the delay between the moment the G-load is reduced and the restoration of vision after visual disturbances will be shorter. From my own experience, I would say that now this delay in visual reactions better corresponds to reality. Also, the time between the complete loss of vision (“black out”) and the loss of consciousness has been brought into better agreement with the research results, and now is about 2 seconds, in rare cases reaching 8-9 seconds. By the way, in the current (older) model, this time ranges from 0.2-0.8 seconds under 6G and higher to dozens of seconds under less Gs. As you can imagine, this change will allow you to better anticipate the moment of G-LOC and to fly near this border with more confidence. I also corrected the effect of temporary and more severe visual impairment, which happens if you pull a high +Gs on the first maneuver with an abrupt jerk (when the pilot was not "warmed up" yet). This effect is associated with the already mentioned above feature of the cardiovascular system hemodynamics. It takes some time for the vessels to "mobilize" and respond to the sudden increase in G-load with an increase in blood pressure. After 5 to 7 seconds from the start of such an abrupt maneuver, while the blood pressure is still "lagging" behind the G-load, the pilot gets a more apparent temporary visual impairment. But after another 3 to 5 seconds, the blood pressure rises enough and the visual function improves. If the Gs are not pulled abruptly, but are rather gradually increased over 5 to 7 seconds, then such a temporary "crisis" of vision can be avoided. This is exactly what is implemented in the new model more clearly than in the current one. Disorientation effect We already have implemented in our older model the "motion sickness" or disorientation effect which was happening in the case of frequent changes in the Gs direction or sign-changing angular velocities. Now this effect will come even faster in order to better imitate the discomfort pilot suffers under alternating positive and negative G-forces. I will not say that the “wobbling” or "dolphin" is physically unbearable. I myself tried to do it in real flight. But it's really damn unpleasant, and I prefer to not do that anymore. Also, this disorientation effect will now come along with the period of recovery after G-LOC (the so-called period of relative incapacitation). It will also manifest itself when approaching the border of LOC, foreshadowing it. Taking into account that, in the new model, loss of consciousness under prolonged G-loads of less than +4..+4.5G will now occur without an obvious tunneling effect, this “dizziness” together with “defocusing” of vision will become a good indicator for you that you are already on the edge. Fatigue indicator By the way, about the fatigue indicator. We decided to heed the popular request and add a G-load induced fatigue indicator to the simple instruments in GUI. When you set the difficulty to “Normal”, you will see a small white triangle in the lower left corner of the G-meter in the GUI. The more your pilot is worn out by the G-forces, the smaller this little triangle will become. Thus, it will give you a rough idea of your current state. As I have repeatedly written on our forum, a real pilot cannot predict in advance what Gs he can sustain during the next maneuver and for how long. He, of course, roughly understands how tired he is. Therefore, this indicator will give you only an approximate idea of the current physical condition of the pilot. When you set the “Expert” difficulty, you will not have this indicator. As a result Ultimately, the new improved version of the pilot's physiology model turned out to be more interesting, detailed, taking into account new important factors and, as a consequence, more “vital” and corresponding to reality. All tests, including the ones with the participation of real pilots, indicate that this model will be the next important step in the development of our simulator, and the realism of air battles will again be raised to the next step with it. This model will get to your computers very soon, along with the next update of the game. Sincerely,

Andrey (An.Petrovich) Solomykin
It’s been a year since we introduced a detailed human physiology model in our simulator. The model which takes into account the limits of human’s G-load tolerance, as well as a number of other factors affecting pilots in flight. This, of course, immediately and greatly changed the dynamics of air battles. They became much more realistic. After all, now, when performing an attack or a defensive maneuver, you have to take into account the fact that a living person with his natural physiological capabilities and limitations is sitting in the cockpit. And that any pilot, of course, gets tired of constantly maneuvering at high Gs. And in the end, there comes a moment when he just needs time to catch his breath and recover. We were interested in your opinion Over the past year, we have read a lot of your comments on the forums and collected a lot of feedback about this model. We have seen that this new and exciting aspect of dogfight has been very warmly received by the bulk of our community, and it's encouraging. While another part of the players asked us to make some changes to this model. In order to understand the situation, a month and a half ago we conducted a poll among players on the .com and .ru forums. What did the poll show? The poll results showed that 60% of players are quite happy with the current model (494 out of 821 unique users on both forums, excluding the extra 31 votes of those who voted twice, i.e. on two forums). And 40% of players would like us to make adjustments to this model. I had carefully read all your comments on the polls. In general, there were more players satisfied with the model on the Western forum, so I conducted a more detailed analysis of that thread and found that 63 out of 381 Western users who chose option 1 (“leave everything as it is”), nevertheless, in comments have written a number of requests for changes in the model. Thus, it became clear to us that the community was divided in opinions approximately 52/48. This means that we cannot leave this situation unattended and we need to think carefully about what can be improved in our model. Collecting new scientific data Over the course of this year, thanks a lot to you, our community, we have collected a large amount of new data from the field of aviation medicine and human physiology under extreme stress conditions (I would like to express special thanks to comrade @Floppy_Sock for the materials he found). This allowed us to take a fresh look at our physiology model and find ways to improve it. For example, a year ago, in my work on a physiology model, I relied mainly on the well-known monograph of the Russian scientist, professor, doctor of technical sciences Boris Abramovich Rabinovich “Human safety during acceleration (biomechanical analysis)”, 2007, where while talking about the duration of the G-loads a human can sustain, he refers to the famous article by Anne M. Stoll, "Human tolerance to positive G as determined by the physiological endpoints." ), published in The Journal of aviation medicine in 1956. This article provides a graph of time to loss of consciousness versus G-load. It is compiled on the basis of the results of 40 experiments,13 of which ended in loss of consciousness by attendants. However, recently we learned that in 2013 there was another article published on the BioMed Central portal in the Extreme Physiology & Medicine section: “The +Gz-induced loss of consciousness curve ”. Its authors, Typ Whinnery & Estrella M Forster, prove there the fallacy of the conclusions from the article of 1956, relying on much broader statistics: now they had already 888 cases of loss of consciousness by testees. These statistics were collected from 1978 to 1992 at a number of US research centers (USAF School of Aerospace Medicine, Brooks AFB, Texas and the Naval Air Warfare Center, Warminster, Pennsylvania). In particular, in their article Tip Whinnery and Estrella M. Foster argue that at high +Gz (that is, acting on the pilot in the "eyeballs down" direction), up to +11.7G, the subjects never lose consciousness earlier than 5 seconds after the start of acceleration, and on average statistically - only after 9 seconds after it. While in our current model, built on the basis of data from the sources published above, loss of consciousness occurs within 3-5 seconds at acceleration of more than 6-7G. Authors of the study explain this difference by the presence of a certain “functional buffer” of the brain, which prolongs the activity of the brain for a few seconds after the arterial systolic pressure at the level of the eyes (brain) drops to zero under the influence of extremely high Gs. In addition, many players asked us to reconsider the pilot's tolerance to large negative Gs (assuming that the deteriorating effect of negative Gs should be more pronounced). They also asked us to implement the so-called push-pull effect (PPE), which manifests itself in a noticeable and very dangerous short-term decrease in the +G tolerance immediately after a negative one. Many aviation accidents on maneuverable aircraft are associated with this notorious effect. Over the past year, we managed to find scientific materials about this effect, too: for example, an article published in 2011 on the scientific, technical and medical portal Springer, co-authored by a number of Chinese scientists “A centrifuge simulated push-pull manoeuvre with subsequent reduced + Gz tolerance ”. This and over three dozen other publications, NASA reports, scientific dissertations, and unique test materials that we have collected, gave us a large amount of numbers that we could rely on with greater confidence. And the need to simulate the above-mentioned phenomena presented me with the fact that it is not just about readjusting the coefficients of the current model. It became clear that the model would have to be built anew, with a more detailed account of all factors acting on an individual and an even more detailed simulation of physiological processes in his body. Today I am glad to tell you about the results of this work. First impressions The new pilot physiology model is currently undergoing a detailed and meticulous beta test. The first impression it invoked in our testers, and which, most likely, it will invoke in you, is “it became more forgiving”. After all, due to the appearance of the “functional buffer” of the brain, quick and short-term maneuvers at very high Gs have now become possible without immediate loss of consciousness. More details... For example, if by a one second long jerk one pulls +7-8Gs, then visual disturbances in the form of a "gray out" (which is loss of color perception) will now occur only 3.5 seconds after the beginning of acceleration. After another 1.8 seconds, the peripheral field of view (the so-called “tunnel vision”) will begin to narrow. The vision will be completely lost (“black out”) after another 2 seconds, that is, only 7.3 seconds after the start of the maneuver. And after another 1.6 seconds, G-LOC (G-induced loss of consciousness) will occur. It has also now become possible to perform, for example, a loop or a split-s with the initial and final G-loads of +5...+5.5Gs without loss of peripheral vision. But if these Gs are maintained during the maneuver for longer than 25 seconds, the “blacking out” will nevertheless begin to happen, and consciousness will be lost 32 seconds after the start of the maneuver. In general, at first you may really think that the pilot has become more resilient, and it has become easier to fight. Has it really become easier? But already after 2-3 days of “test flights” our testers found that the first impressions were somewhat optimistic. Yes, you can now actually “kink” the trajectory more sharp. Once, twice ... but you won't be able to maneuver for a long time, while constantly holding high Gs. You will have to reckon with fatigue and a decrease in the pilot's tolerance to G-forces during the battle, just as before. And just as before, you will have to plan well the trajectories of the fight, choosing the moments when to “pull” and when to let yourself catch your breath. About endurance and fatigue As I wrote above, we have collected a large amount of scientific data on a human's tolerance to +Gs and -Gs of different magnitude. Unfortunately, some of them are contradictory, and there is no one single model of the “average person” that would reliably describe our “average” endurance. In one source, you can find information that an experienced aerobatic pilot can withstand +2Gs only for 13 minutes, while in another source, you can find a figure that the + 3Gs are quite normally tolerated within an hour. At the same time, when we talk about larger Gs values, the numbers from different sources become closer to each other. But still, this subject has some field open for discussion. Therefore, the endurance of our pilot to long-term G-loads, as well as to cyclic G-loads in the new model is adjusted both taking into account reliably known data from various publications, and based on the impressions of real pilots with aerobatic experience. We have involved military pilots and pilots flying on sports aircraft in testing. They all praised the results achieved, and admit that the model reproduces their own feelings quite closely.

If you pull, for example, +6G in one-two seconds, withstand it for five seconds (this is when you will get the partial “tunnel vision” effect), then reduce to 1G, pause for five seconds, and then create the same +6G for the same five seconds again at the same rate, then in the second case there will be no “tunnel vision” effect. But the same maneuver made third in a row will again lead to a partial "tunnel vision". But this is already because of a decrease in the tolerance limit due to excessively intense load without sufficient recovery time. Backrest angle Over the past year, there were many attempts by some players to prove that there are differences in the endurance of the pilots of one or another coalition. Although the physiological model of a pilot was the same and did not depend in any way on the plane in which he was sitting.

If the AGSM is performed incorrectly, then the effectiveness of such a technique is sharply reduced. As you know, during the World War II, pilots did not undergo special training on centrifuges, and were not trained to perfectly perform AGSM as modern fighter pilots are. But even then it was known that the tension of the muscles of the press and legs together with strained breathing allows one to endure higher Gs. Taking these facts into account, the pilot in our game (just as before) performs the AGSM not “excellently”, but “somehow”. This increases his tolerance limit for prolonged G-loads from 5.5G in a relaxed position (statistics are on the chart below) to 6.7G. This is about 0.4-0.5G more than in the current model. Such a slight increase in the limit of the maximum tolerated long-term positive G-load, however, will now make it possible to maintain a g-load of +6G with a partially narrowed peripheral field of view, up to a complete loss of vision within 18 seconds. Loss of consciousness under this Gs will occur in another 2 seconds.

These options are designed to improve weapon effectiveness depending on the type of target. The graph below demonstrates this effect. Effect of desired terminal vertical angle on GBU-38 bomb path Due to aerodynamic restrictions precise impact points are not always possible, in this case, JDAM uses an algorithm to check the impact heading and vertical angle. If the check indicates a noticeable miss, the algorithm will seek for conditions that will allow for an on target hit. In addition, to reduce the probability of a near miss and to improve ballistics penetration, the autopilot will command a zero angle of attack during the last seconds of flight. Viper AGM-65 Updates We encountered a target lock issue with objects in close proximity to the desired enemy. Symbology errors on the WPN page will be fixed in the next update. The seeker depression angle markers are currently being adjusted as well as the Sensor of Interest (SOI). In the next Open Beta update, the addition of the BSGT option and uncage ability will be added. The LOS handoff indication on HUD can also be expected. The possibility to engage target lock with two missiles prior to launching the first will also become available. It will be possible to ripple fire two locked-on missiles with RP 2 option. We are also working on the TMS-right re-command handoff. Thank you again for your passion and support, Kind regards, Eagle Dynamics Team

Il2 DD Update Dev Blog 262
By 76.IAP-Blackbird,
Dear friends,
Today we'll continue to show you the progress of the aircraft currently in development. The hero of the day is two-seater this time, twin-engine fighter/bomber De Havilland Mosquito F.B.Mk.VI Series II we're making for Battle of Normandy. This famous and popular WWII British RAF plane had an unusual and distinct look (well, the same can be said about most British aircraft). But it's interesting not only because of its appearance - it reached high speeds in its class despite being partly wooden. Moreover, it kept its high-speed capability even when carrying bombs thanks to the internal bomb bay.
2000 pounds of bombs, four 20mm guns and four 7.69mm MGs the Mosquito carried made him a dangerous adversary for the enemy. In our sim, there will be additional weapon modifications available - eight RP-3 unguided rockets and 57mm anti-tank gun (!). Here are the first 3D renders of this bird of prey at its current development stage:
The recently announced player controllable mobile AA guns are also showing good progress. Along with the work on their visual models, we're improving the realistic physics model of the wheeled ground vehicles movement even more. And don't forget about their crews as well:
DCS Weekend News 25 September
By MigBuster,
25 September 2020
Dear Fighter Pilots, Partners and Friends,
We are pleased to announce DCS: MB-339A is coming to DCS World. This exciting project comes to us from a group of flight simulation and aerobatics enthusiasts who saw DCS as the ideal platform to pursue their virtual flights. The MB-339 is an excellent fighter-trainer, and the simulator is being used by the Italian Air Force cadets.
As DCS: A-10C II Tank Killer prepares for takeoff, we are happy to share our development progress on the AGM-65L Laser Maverick, GBU-54 Laser JDAM and APKWS laser-guided rocket. We are confident that this major upgrade will be an exciting addition to this iconic and effective weapons system. Check out the Tank Killer introduction and Laser Maverick video and how to use GBU-54 Laser JDAM.
The Aircraft Owners & Pilots Association is running their Thunder Over Kutaisi 2020 Livestream Airshow on the 26th of September at 20:00GMT. Watch the trailer.
Thank you for your passion and support.
Yours sincerely,

A-10C II Tank Killer
Development Update
DCS: A-10 II Tank Killer is currently undergoing a lengthy closed testing period to ensure accuracy, stability, and a smooth launch. We continue to improve the Helmet Mounted Cueing System (HMCS) indicators, add more skins and mission content, and tune flight model changes. We encourage you to get familiar with the new weapon systems to hit the ground running.
This update is being developed in parallel with the A-10C VR Training Software for the United States Air Force 355th Wing.
AGM-65L Laser-Maverick
Development Progress
In this video we introduce the primary features of this substantial update and instruct on the use of the AGM-65L laser-guided Maverick. The Laser-Maverick provides excellent range and ease-of-use to lock onto a target by using the targeting pod.
GBU-54 LJDAM
Development Progress
The GBU-54 is a 500-pound bomb with options for INS/GPS and laser-homing guidance. It can be loaded on all 1760 smart racks.
While INS/GPS allows launch-and-leave and the ability to engage through cloud and smoke cover, the laser-guidance provides increased accuracy and can engage moving targets. It’s up to you to determine the best guidance based on the engagement.
Watch DCS: A-10C II Tank Killer - GBU-54 Laser-JDAM.
AGR-20A APKWS
Development Progress
The Advanced Precision Kill Weapon System (APKWS) is a cost-effective method of engaging unarmored and lightly armored targets based on pinpoint laser-guidance. Both M-151 high-explosive and M-282 penetration warhead versions are available with seven rockets per each LAU-131 rocket pod. With a range of approximately 5 miles, the APKWS offers accurate firepower.
Get a grip on how to use the APKWS with DCS: A-10C II Tank Killer Laser-Guided Rockets.
