Hello everyone!
 
The holidays are over and the new year is upon us. This means that Battle of Moscow release comes closer with every passing day.
 
Six out of ten new planes are already available to players and three ones will be ready in a month or so. The tenth and final BoM aircraft is the most complex one: Ju 88 A-4 bomber. Its development process is the most intensive one at the moment,  five specialists are working on it every day. In the same time, mission designers are making the campaign since Moscow area map layout is final.
In the same time, artists are busy making official skins for new aircraft. 50 new skins (half of the required amount) are already finished, 50 more left. We'd like to show you these skins today:

Hello!
 
Today is an important day for the project - we start the beta test of three new Battle of Moscow timeframe planes at once: Bf 109 F-2, IL-2 model 1941 and Pe-2 series 35. If all goes according to the plan, these planes will be available to all owners of Battle of Moscow next week. It's possible that the new update will be postponed for a week because of the large amount of new content, but let's hope for the best :)
 
Bf109-F2.jpgPe-2-35.jpgIl-2-41.jpg
 
As we said earlier, we started the discussion on what we'll be doing later this year. Long term planning requires long discussion, so we'll be able to give an answer to the question 'what will come next after Battle of Moscow' both to you and ourselves closer to its release. In the meantime, we created a list of improvements for our flight model department we'd like to have in the coming months. It consists of two independent parts that will be worked on in parallel, and the tasks are arranged in the order they will be done (the list is likely to be corrected as the work goes though). So...
 
Complex tasks that require significant changes or research to find their cause:
1. Find and eliminate the cause of invisible planes sometimes appearing in multiplayer (which is very hard thanks to the system complexity);
2. Fix the issue that causes stopped engines to start and stop again for some time;
3. Fix the issue with a plane turret controlled by another player not correctly disappearing after plane crash;
4. Fix the issue with proppeler dust wash effect not disappearing immediately after crash;
5. Damage model imrpovements: make hits to wing roots damage longerons and cause wing fracture;
6. Fix the issue of Pe-2 propeller sound remaining after engine (and wing) loss;
7. Improve engine start procedures on all planes by setting engine control axes to positions convenient for taxiing and take off;
8. Add a button to reset rudder axis to middle position (useful for players who use buttons to control it);
9. Improve flight model control tools that will make development process of new aircraft FMs more efficient;
10. Additional research of airplane sideslip angle influence on plane roll;
11. Additional research of dynamic airflow compressibility and its influence on plane diving and control effectiveness (previously we based FM adjustments on manuals that stated 750 km/h velocity limits, while some test reports contain data of planes achievieing significantly faster speeds in dive, when dynamic airflow compressibility is ought to be taken into account);
12. Mouse control: make the control assist react to small direction changes less vigorously;
13. Fix the issue of BF 109 E-7 - it shouldn't 'squat' when you engage brakes;
14. Fix the issue of several planes: wind can somewhat swing them on the rear wheel while parked;
15. Improve wheels modeling, that will make large planes with low power engines, but big wheels to taxi easier;
16. Improve autolevel flight assist for non-dive bombers (He-111, Ju-88, Pe-2 s. 87 and Pe-2 s. 35) so it will use rudder instead of ailerons for corrections;
17. Add engine detonation affect caused by a variety of causes (wron mixture, high miture temperature, engine overboost, etc. );
18. Add weapon misfires caused by overheating;
19. Develop more sophisticated high-G effects system so it will affect plane crew depending on their weariness, oxygen amount, wounds, etc.;
20. Make bailing out impossible during heavy rotations or other hard maneuvers;
21. Make pilot head movement more realistic by adding a simple spine model;
22. Add united controls for different adjustable stabilizers;
23. Make twin engine coolers on Bf 109 F4, Bf 109 G2 and Ju 87 D3 more detailed (currently always left cooler emits vapor when any radiator is damaged);
24. Add emergency cooldown systems to aircraft where applicable;
25. Make fuel system simulation more complex (more detailed tanks system, allow player to control engine flow and control fuel amount manually, more detailed fuel leaks and self-sealing process, fire probablity based on remaining amount of fuel inert gas pressurization, external fuel tanks.
 
Regular tasks:
1. Check and correct fineness ratios of all planes with their flaps extended;
2. Correct La-5 engine damage model (overheat damages it too fast now);
3. Correct Fw 190, Ju 87 and He 111 engine damage models (engine rotates for a long time with propeller blades bent);
4. Implement MC 202 flaps safety system that retracted them at high speeds to protect them from damage;
5. Correct Bf 110 flaps system to make flaps extension incremental in all cases;
6. Correct He 111 trimmer so it won't stop moving before value reported in technochat reaches 100%;
7. Correct (invert) He 111 trimmer;
8. Add landing gear breakability to all planes where it is missing;
9. Correct 'jumpy' behavior of Bf 109 F4, G2 and F2 to resemble E7 behavior and check other planes;
10. Implement jamming and self-closing of sliding canopies from high speeds and pitching/diving;
11. Correct Pe-2 issue where throttle control assist leads to oscillating throttle value at full setting;
12. Set up different radio frequencies for own and enemy planes;
13. Add tips to technochat;
14. Invert certain values in technochat (for example, trimmers);
15. Manual mode switches on planes with automatic governors should also turn off the corresponding in-game assist;
16. Bf 109 flaps control wheel should also jam when the flaps jam;
17. Planes with powered front armament will have their fire capability blocked after power loss;
18. Add reserve guns reload systems where applicable;
19. Implement smoke generators;
20. Improve hand shake effect to correspond to engine RPM;
21. Improve force feedback effects on FFB capable joysticks (taxiing over bumpy field, ground impact when landing without landing gear);
22. Correct gun fire FFB effect (it shouldn't be influenced by plane speed as it was reported to be the case on P-40);
23. Make it possible to torn off all I-16 landing gear covers in dive;
24. Make it possible to torn off upper Yak-1 landing gear covers in dive;
25. Yak-1 upper landing gear covers should be torn off in an event of corresponding wing loss;
26. Address Ju-87 oscillating engine RPM issue that happens during take off at maximum throttle;
27. Animate radiator control buttons on Ju-87 and Pe-2;
28. Turn off electric thermometers on parking for the planes with powered thermometers;
29. Jam compasses at high roll values;
30. Improve oxygen system modeling on German planes;
31. Correct Fw-190 adjustable stabilizer indicator;
32. Conduct additional research of LaGG-3 and La-5 takeoff ability with strong side wind;
33. Correct Ju 87 engine thermal modeling;
34. Correct 'near stall' audible cue on Bf 110 E-2 (currently these sounds can be heard even with minimal pitch corrections).

Hello!
 
Today we're assembling Ju 88 A-4 cockpit consisting of 4 crew stations. Required animations are being made right now. We plan to have working quick mission mode for Moscow map by the end of this month and start campaign beta-testing in early March.
 
There is a plenty of work going on Battle of Moscow, but we aren't forgetting about optimizing the sim as the whole. Some old multiplayer bugs are very hard to reproduce on purpose, for example, a bug with bombs or turrets appearing in a wrong place takes up to 100-150 re-spawns to reproduce it. So we need to choose another approach to find its cause - add special logging to the public version of the game and analyse the submitted results. Next week we plan to release 1.107b hotfix that will include many changes and this additional logging to find the cause of this elusive bug.
 
1.107b version changes:
 
Global:
 
1. We'll add crash dump files saving. There will be a special forum thread for submitting such a file if you encounter a game crash, helping us to find and fix it;
2. Workaround for 'invisible planes' bug added (it doesn't fix the cause of their appearance since it is still unknown but eliminates its consequence);
3. Logging for 'invisible planes' bug added (we'll create a special forum thread about it to collect logs submitted by players);
4. Performance in the first Soviet scenario mission (first, summer, chapter of Stalingrad campaign) improved;
5. Crash that could happen while playing back large recorded tracks has been fixed. Unfortunately, tracks recorded in previous versions of the game won't work, so please consider video capturing your favorite ones if you'd like to keep them;
6. Compatibility with third party overlay software improved (for example, Steam and Teamspeak overlays);
 
Features:
 
7. It will be possible to tell which side controls an airfield before choosing your own allegiance in multiplayer;
8. Multiplayer mission author will be able to specify a range of allowed unlocks, not just individual ones;
9. IL-2 sight can be moved back and forth using Lalt-F command;
10. Light reflection and relief detail improved on thin metal parts of IL-2 model 1941, IL-2 model 1942, I-16 type 24, MiG-3 series 24, Pe-2 series 35, Pe-2 series 87, LaGG-3 series 29, La-5 series 8, P-40E-1, Ju 87 D-3, Bf 110 E-2 and MC.202 series VIII;
11. MC.202 cockpit canopy textures improved;
 
Physics changes:
 
12. Fineness ratios of all planes were re-checked with their flaps extended. Fineness ratio was decreased for LaGG-3 series 29, La-5 series 8, Yak-1 series 69, IL-2 (both) and P-40E-1. Other planes fineness ratios were found to be correct;
13. Twin turret machine guns are now reloaded one after another (not simultaneously);
14. Bf 109 F-2 radiator functioning in manual mode was corrected: it opens fully, but slower. There are contradicting sources available - text one and hydraulic schematic. Text one says "die kuhlerklappen durh den luftdruck geoffnet" which means that radiator was opened by approach flow. However early Bf 109 F-2 hydraulic schematic shows that radiator was manually opened by fixing the valve in 'open' position. After discussion we decided to follow the schematic;
15. MiG-3 cooling system has been corrected: now it requires opening its radiator to degrees similar to other Soviet aircraft, but at higher altitudes (since its power output maxes out at higher altitudes);
16. MiG-3 elevator trimmer won't work if the right side of the elevator is lost (where trim tab is located);
 
Other changes and fixes:
 
17. Selected modifications won't reset after re-entering the modifications screen;
18. Spotters correctly spot enemy aircraft closer than specified distance (with the exception of ground vehicles that can't be detected closer than 3 km);
19. Track playback progress bar corrected;
20. Wingmen correctly drop bombs after leader (player) while carrying out 'do like me' order;
21. AI gunners will fire at any planes, not only fighters;
22. Various graphical bugs caused by crossroads fixed (missing triangles, missing crossroads or road parts, etc.);
23. Airfields and taxi ways pavement corrected for autumn Lapino map;
24. Roads will look correctly in overcast light conditions;
25. La-5 canopy texture mapping fixed as requested by skin authors (it is no longer symmetric);
26. Mission editor won't crash after repeated loading of missions containing many objects.
 
A bit more info about Battle of Moscow. Today we can show you preliminary (there are no trees in the city yet) screenshots of Moscow as you'll be able to see it in the game from the border of flyable area.
Moscow_1.jpgMoscow_2.jpg
Moscow_3.jpgMoscow_4.jpg
Moscow_5.jpgMoscow_6.jpg
As you can see, while the city is effectively a scenery set, its level of detail and accuracy is unprecedented among WWII sims. The city layout of 1941 recreated in the game is historically accurate (different from the modern one), there are major landmarks, all bridges and so on.
We can show you some more autumn Moscow map screenshots as well (it is 90% completed):

Hello everyone!
 
With Battle of Moscow project being close to its finish, we have some time to spare on the tasks that were postponed for a long time. In the developer diary #120 we told you about our plans to improve physics and aircraft systems, bomb sights are also being worked on. In the recent update 1.107b we added the more flexible modifications filter system requested by many multiplayer server owners and the additional logging to assist us in the search of hard to find issues like invisible planes in multiplayer and crashes that happen sometimes.
 
Among other things for the next update 1.108 we're preparing aircraft information that will be accessible for each plane in player profile and in full screen map mode during a flight.
 
Collecting the data required for it wasn't that simple since many of the reference values are 'soft data', many depend on an aircraft mass and configuration which are different in different tests performed back then, so it was needed to do ingame tests to measure them. These characteristics aren't specified in the game code: they are the integral result of a really complex physics simulation system. When our engineers build a plane, they set and tune aerodynamic elements and engine parts, aiming to meet the reference data available (such as maximum speeds, climb rates, lift-drag and trim curves, takeoff and landing run lengths when available, etc.). Moreover, the reference data analysis is always a research task, so there could be different cases. In some cases there is not enough reference data available and thorough engineer analysis is required to make an educated guess while keeping other values close to the reference data. In other cases, there could be several contradicting sources and we need to determine which one is more credible.
 
Characteristics presented below were measured in the game, which took almost two weeks of hard work. In the end we've got informative and standardized data for all planes in the game we'd like to present you below:

Hello everyone!
 
Today we'll show a bit of Ju 88 A-4. The plane is shaping up and it turns out to be an interesting one. First, it has a rich instruments array. Second, it can carry a huge bomb load, almost as heavy as He 111, but Ju 88 is actually a dive bomber, thus it can deliver its bombs with significantly better accuracy. Third, there are interesting engineering decisions that appear in our sim for a first time, for example, radial radiators positioning around engines or significant armor protecting the gunners. Fourth, this bomber can carry up to 44 50 kg bombs, no other plane in the sim can carry so many. Fifth, unlike He 111 H-6, its turrets are armed with MG-81 belt fed machine guns with high rate of fire that allow a thicker defensive fire curtain.
 
This aircraft will enter beta stage soon, but today we can show you screenshots of its cockpit and the video:
01.jpg02.jpg
03.jpg04.jpg
05.jpg06.jpg
07.jpg08.jpg
https://youtu.be/Yc4DmdFL2Ts
In addition, last week our engineers tested the planes turn time and climb rate, so we updated the Dev Diary #123 with the corrected data. Fw 190 flight model was also corrected (thanks to [i.B.]ViRUS for his cool finding of additional Fw 190 A-4 Lift-Drag curves) so its turn tume and climb rate correspond to the reference better.

Hello everyone!
 
Battle of Moscow open beta is available for BoM owners for three weeks now. Of course, during this time we were busy improving the game.
 
First, the map of Moscow region has been improved, more evergreen trees were added. They weren't simply added to existing forests at random - forest types reflect the real forestation in the area. You can see the forest type map below: violet color for pine, red for spruce, yellow for leaf, blue and aquamarine for mixed forests.
_forests.jpg
__listva_a.jpg__listva_w.jpg
__sosna_a.jpg__sosna_w.jpg
__elka_a.jpg__elka_w.jpg
 
Second, we use the time it takes to finish the campaign cutscenes to improve the campaign missions. Additional story scenarios for the campaign are ready, as well as tactical overlays that show the current situation at operational level:
1.jpg
2.jpg
3.jpg
4.jpg
5.jpg
 
Third, we're making some changes and additions to the campaign. We'll describe them in detail later, but here is a teaser:
_ranks.jpg
 
All in all, our team is adding the finishing touches to Battle of Moscow and we are confident that it will be a worthy addition to the flight sim genre.

Hello!
 
While Summer is at its peak, our team continues the work on improving IL-2 Sturmovik. Battle of Moscow will be released on Steam in a couple of weeks, so we're changing the way the content is represented. Among the other changes there is one we think you'll especially like - in the coming version 2.003 you'll be able to connect to a multiplayer server even if you don't own the map it uses. In addition, you'll be able to pilot the planes from Battle of Moscow in Battle of Stalingrad campaign if you own both theatres and these planes saw action there historically. For example, you can use MiG-3 and I-16 in Stalingrad campaign and a couple of Battle of Stalingrad planes in Battle of Moscow campaign.
 
Gunfire sound effects are overhauled, they became more 'alive' and realistic. We also finish polishing the campaign for now - in later versions we'll be extending it, adding new mission types and scenario missions. Several performance improvements will be included in 2.003 as well.
 
By the way, we're working on new aircraft and features we'll tell you about a bit later. Here are a few WIP screenshots for now:
01.jpg02.jpg
03.jpg04.jpg
 
And here is the video showcasing a new feature. Some members of our community were asking for it for a long time:

Hello Everybody, 
 
This month was very hard for us, but productive. We managed to release the huge update 2.006 on time and to include all the improvements we planned for it. As we expected, such amount of deep changes resulted in several 'teething problems' but thanks to the team’s hard work and community’s help we quickly solved the most important ones. We'll fix the remaining ones in time.
 
As we announced earlier, today's Developer Diary is dedicated to creating scripted campaigns and how you can do it. A Scripted Campaign is a sequence of missions a player should complete one after another. These missions are usually hand-crafted and not created by a generator. Missions for the campaign are created in the Mission Editor (many of you are already familiar with it) just like regular single or multiplayer missions. A campaign mission doesn't differ from a single mission much - it must contain a special TRA_Objective trigger with player coalition specified and Success property for a Primary Objective. This trigger must be 'pinged' when the player does something you consider as mission success, then the next mission in the sequence will become available to fly. By default, at mission start, this property is not set. By the way, you can set the mission status to failed even after making it successful - you can 'ping' another TRA_Objective trigger with this property set to Failed.
 
The second difference between a Campaign and Single Missions is that the mission type must be set in its properties so it would be recognized as a Campaign mission. You need to set mission type to Campaign so it won't be displayed in single missions list (which islocated in data\Missions\ folder), but will be visible in a campaign missions list (in data\Campaigns\\ folder).
 
In addition, the folder of your campaign should contain these files:
 
1. info.txt - main config file
2. info.locale=***.txt - campaign text description in different languages (*** - eng/rus/ger/spa/fra/pol). If you don't have translation for certain language, don't include the text file for it, simple.
3. campaign.png - campaign cover picture shown in Scripted Campaigns menu (420x420 pixels)
4. **.Mission - mission in text format created by Mission Editor (** - mission number in sequence, for example, 09). These files are optional and you can delete them when you're distributing the campaign.
5. **.msnbin - mission in binary format created by Mission Editor (** - mission number in sequence, for example, 09)
6. **.eng/rus/ger/spa/fra/pol - texts for each mission (mission title, briefing, subtitles, map icon names) in different languages (** - mission number in sequence, for example, 09)
7. **.settings - config files for each mission (** - mission number in sequence, for example, 09)
8. **.png - mission title picture shown on the campaign screen when you select a mission, 940x500 pixels (** - mission number in sequence, for example, 09)
9. **.coalition=*.tactics - (optional) vector image containing tactical overlay for a mission (** - mission number in sequence, for example, 09, * - player coalition, 1 for Allies, 2 for Axis Powers).
 
Now let's go in detail. The main config file info.txt contains these parameters:
 
1. &order=* - campain position relative to other ones in the list (paid campaigns will show up first anyway)
2. &free=* - set it to 1 if you distribute a campaign for free and to 0 if it must exist in player account to be available
3. &tows=* - required theatres of war divided by commas (BoS = 1, BoM = 2, BoK = 3). Player aircraft used in the campaign must be included in these ToWs (for example, campaign that is taking place on Stalingrad maps, but where player should pilot MiG-3, should have this parameter set to &tows=1,2)
4. &planes=* - Collector Planes required by the campaign (player should be able to fly these planes) divided by commas (for example, &planes=luascripts/worldobjects/planes/la5s8.txt,luascripts/worldobjects/planes/yak1s127.txt). This is the current list of Collector Planes:
luascripts/worldobjects/planes/la5s8.txt
luascripts/worldobjects/planes/fw190a3.txt
luascripts/worldobjects/planes/p40e1.txt
luascripts/worldobjects/planes/mc202s8.txt
luascripts/worldobjects/planes/yak1s127.txt
luascripts/worldobjects/planes/ju523mg4e.txt
5. &missionsAmount=* - total missions amount in the campaign
6. &showFutureMissionsNames=* - set it to 1 to show names of not yet unlocked missions and to 0 to hide them
7. &showFutureMissionsDescriptions=* set it to 1 to show descriptions of not yet unlocked missions and to 0 to hide them
 
Config file **.settings allows campaign designer to impose restrictions for each mission:
 
1. &lockAmmoSchemes=* - set it to 1 to allow only the preset weapons loadout or to 0 to allow player to choose
2. &lockPaintSchemes=* - set it to 1 to allow only the preset skin for a player aircraft or to 0 to allow player to choose
3. &lockFuelAmount=*  - set it to 1 to allow only the preset fuel amount for a player aircraft or to 0 allow player to choose
 
It is also possible to create a map overlay for each mission with enemy positions and other info drawn on top of the navigation map:
 
This map overlay is stored in *.tactics files which are basically SWF format files created in Adobe Flash. So you need to create SWF format files in Adobe Flash and then rename them from *.SWF to *.tactics.
They should be named like this: 02.coalition=1.tactics, where 02 is the mission number in sequence and 1 is player coalition ID (1 are Allies and 2 are Axis).
 
SWF file requirements
 
You need to set the size of SWF file area so it will have one pixel per 200 meters on the game map. For example, Moscow map is 281600 x 281600 meters, so you need to create an SWF file with 1408 x 1408 pixels working area.
The file shouldn't contain fonts, they must be converted to curves.
All the lines should be converted to Fills.
Intersecting objects must be made a single object if you don't want for intersection to be visible.
The file may contain groups, movie clips and layers for easier work.
Timeline should contain a single frame.
 
Overlay design recommendations
 
Allied forces are light blue - #006CAB
Enemy forces are red - #930808
Don't use translucency for main objects like front lines, arrows, text, symbols.
Use 9% translucent object to show a controlled area.
Use 13% translucent object to show a special area.
Use PF DinDisplay Pro font for text.
Please take a look at a sample file for Adobe Flash.
 
Tactical map overlay sizes for existing maps
 
Stalingrad - 1792 Х 1344
Lapino - 256 Х 256
Moscow - 1408 Х 1408 
Velikiye Luki - 832 Х 624
Novosokolniki - 256 Х 256
 
Finally, here's how you can distribute your campaign in the community.
 
To distribute a free campaign, just zip the folder containing your campaign (data\Campaigns\\) and put it anywhere on the forum, web, etc. Players should unzip it into their data\Campaigns\ folder and they are set.
 
If you want to sell your campaign:
 
1. Make sure you don't give mission files to anyone who can distribute them for free.
2. Make sure your campaign is good enough and other players would pay money for it. 1CGS reserves the right to not sell every Campaign produced.
3. Contact Producer Jason Williams via personal message (https://forum.il2sturmovik.com/user/13-jason_williams/), preferably even before starting the work on the campaign and reach an agreement on all the details required for selling it.
4. Copy protected campaign can be created just like a free one, but requires mandatory testing in cooperation with our team, protecting mission files and adding it to our account system.
5. Copy protected campaign can be distributed like a free one (an separate installer containing protected mission files instead of unprotected ones) or can be included in official updates (this depends on agreement between campaign author and our Producer).
6. All payware Campaigns must be sold through our online store. 
 
A sample campaign is provided in .zip file attached to this post for your reference:
 
We plan to improve Scripted Campaign mode in the future, adding ability to playback audio and video files in mission briefiengs, interactive dialogs during a mission and other interesting features. We hope that this new mode will attract talented mission designers to all the community benefit.

Hello everybody,
 
First, let's start with a short overview of the current development progress. We prepare for beta-test of the new version 2.009 release candidate. Implementation of the Open VR API is nearly finished and we're 'polishing' the new features, including some that aren't directly related to VR. In the meantime, engineer department works on IL-2 mod. 1943 and Spitfire MkVb flight models, while artists are making 3D models of Hs-129 and Yak-7b.
 
Here comes the main hero of the today Dev Diary - IL-2 mod. 1943 aiming sight. Starting from early 1943, PBP-1 collimator sights were gradually replaced by simple VV-1 (Vizier Vasilyeva - first) mechanical sights on IL-2s. It is commonly believed that PBP-1 aiming sights caused many injuries during emergency landings that were especially frequent among Sturmovik pilots. While being very simple from a technological point of view, this aiming sight actually was more capable than VV-1 was. For example, it could be used for:
aiming at air targets;
aiming rockets at ground targets from different distances;
low altitude level bombing.
Today we'll tell you how to aim using VV-1 sight.
 
Aiming at air targets using VV-1 sight
There are special markings on the IL-2 mod. 1943 windshield - crosshairs and two special oval rings. These ovals are drawn in a way so when pilot's eye is correctly positioned on the aiming line 0.5 meters behind the windshield, they look like round concentric rings. When at this position, a pilot needs to align the main crosshairs with the bead to hit a target 400 meters away flying at 400 km/h speed (same as the IL-2 speed). This sight can also help to estimate the required lead depending on the target aspect angle:
Target with aspect angle 0/4 behind (pursuit shooting) should be placed at the center of the sight;
Target with aspect angle 2/4 behind (shooting in 45° turn) should be positioned on the inner ring facing the sight center;
Target with aspect angle 4/4 (moving perpendicularly at 90°) should be positioned on the outer ring facing the sight center.
On these two screenshots you can see these lines and how targets are looks like at 400 meters:
01_gun_Sight.jpg02_gun_Aim.jpg
 
Aiming rockets at ground targets using VV-1 sight
Unlike PBP-1 aiming sight that could be used to aim rockets at ground targets at 800 meters or less, VV-1 includes additional horizontal lines for different ranges. A pilot needs to prepare his ground attack run early to achieve 350-450 km/h speed at 30 diving angle (so he should begin the dive from at least 1500 meters altitude, reduce airspeed to 220-250 km/h and maintain low throttle while diving).
 
To aim, a pilot should decide at what range he will launch the rockets, position his eye on the aiming line, then align the bead with a chosen horizontal range mark and fire rockets when this distance is achieved. You can see the aiming process on the following screenshots:
03_rct_diveangle.jpg04_rct_DiveAngleProjection.jpg
05_rct_1600.jpg06_rct_1200.jpg
07_rct_0800.jpg08_rct_0600.jpg
09_rct_0400.jpg10_rct_Fire.jpg
 
Low altitude level bombing using VV-1 sight
While usually Sturmoviks dropped their bombs while diving, dispersing large amounts of bomblets required level bombing from low altitudes. A special aiming sight was needed since the aircraft engine cowling blocked a pilot's view to a target. VV-1 aiming sight has special horizontal lines on the windshield and curves on the engine cowling that allow a pilot to determine a moment when he should release the bombs. This is how it works:
 
A pilot should choose a target and determine the approach direction (if he engages a transport column or another extended target, approach direction should be chosen along its length). In addition, he should note a reference landmark at 300-500 meters distance to the side of the target, perpendicular to the approach direction. This landmark is needed to determine when to drop the bombs.
11_bmb_Start.jpg12_bmb_TargetLocating.jpg
 
A pilot should fly to the point where he will begin the bombing run, 3-5 km away from the target. He should approach this beginning point at a chosen bombing altitude (50, 100, 200 or 300 meters) and 360 km/h speed;
After turning to the approach direction, a pilot should maintain the approach direction, a chosen bombing altitude and 360 km/h speed.
13_bmb_RunInPattern.jpg14_bmb_Approaching.jpg
 
During the bombing run, a pilot should position his head correctly to aim the bombs: one of the two lines on the windshield should be aligned with a corresponding altitude curve on the engine cowling (PageUp and Insert keyboard keys could be used for this).
15_bmb_Marks.jpg
 
Bombs should be released when the imaginary continuation of this horizontal line passes the previously chosen reference landmark to the side. Here are several screenshots that show the correct pilot head positions for different bombing altitudes and bomb release times.
 
Bombing altitude 300 meters. Lower line on the windshield should be aligned with the 1st (rear) line on the engine cowling:
16_bmb_300_Aiming.jpg17_bmb_300_Drop.jpg
 
Bombing altitude 200 meters. Lower line on the windshield should be aligned with the 2nd line on the engine cowling:
18_bmb_200_Aiming.jpg19_bmb_200_Drop.jpg
 
Bombing altitude 100 meters. Upper line on the windshield should be aligned with the 3rd line on the engine cowling:
20_bmb_100_Aiming.jpg21_bmb_100_Drop.jpg
 
Bombing altitude 50 meters. Upper line on the windshield should be aligned with the 4th (front) line on the engine cowling:
22_bmb_050_Aiming.jpg23_bmb_050_Drop.jpg
 
VV-1 aiming sight allows to launch rockets and drop bombs with adequate accuracy during calm and warm weather. However, it should be noted that crosswind complicates the aiming of rockets and bombs significantly. In addition, at low temperatures (during winter) and low altitudes the true air speed is significantly less than indicated air speed. There was no universal method to take these errors into account, so bombing during bad weather required a skilled pilot.
