While flying in the rain or a high humidity environment the engine will produce slightly more thrust at the cost of the higher consumption.

Hi, This is a known issue. The current iteration of the FM and CDVE is not final and we already have a internal build where the aircraft is neutrally stable and the elevons are behaving as they should. We even have implemented the USEL (Ultime secours, Last resort) control mode, where the stick directly control the elevons. This internal version is still work in progress and might take some time to be released as we want it to be perfect. The Mirage 2000 has a tricky airframe and it proved difficult achieve a correct result. We feel the current OB version is good enough for now until we have the final FM and CDVE. As soon as we have more info to share we will, thanks.

As already said multiple times the Mirage is over-performing in sustained turn rate, this is most noticeable at low speed. We already have an internal version that resolves these issues and bring the STR to more realistic values. We are very confident in the engine performance and consumption. This means that the climb rate and acceleration rate are realistic. As you said, what you think does not matter, what matter is data :). We are confident that our internal build is the most accurate representation of the Mirage 2000C performances possible. Once it's released, if anyone has data that could highlight some issues with our implementation, we will be very happy to review it :). The engine thrust and consumption chart are available in the Mirage Manual, some time after the FM/CDVE update is release we will also add EM charts to the manual.

Hi, This has been fixed internally and will be resolved in one of the next updates.

You can install it by selecting the MAGIC and DDM in the rearm window.

As said above, the video is wrong the aircraft is not having 17 °/s turns at these speeds....... We know the aircraft is over-performing in STR by ~10% at worst, but we already have a reworked FM version in development that resolved this issue. As soon as the reworked FM and FBW are ready we will release them and then you guys can compare the turn rates :).

Hi, Markpoints no longer display M91. M92 and M93 lights on the PCN. This is only a feature of the Mirage 2000D INS and is not present on our 2000C. Thanks.

I edited the above post, I miss-read and thought OP was talking about training missions.

Hi, No, the training mission are not up to date with the latest changes for the aircraft. I'm working on updating them but it takes a lot of time. Thanks.

Hi, Razbam did not produce any training videos on the Mirage so it's dependent on the content creator to update his videos. This French youtube channel has a lot of up to date tutorials, most of them have English subtitles : https://www.youtube.com/c/dilixo The manual is fully up to date with the latest change, I suggest you use it to get back to speed on the Mirage. Thanks.

Most fighter aircraft roll on idle IRL when lightly loaded. A reactor still produces a non-negligible amount of thrust at idle. I know the A-10 or the F-16 does it for example. In DCS we had to use a "hack" to make it work for the mirage

Hi, Yes the engine update has been released today Wednesday 22/06/2022. Sorry for the missing patch notes.

Thanks for the kind words. The pilot needs to maintain MIL power avobe Mach 1.4 by himself, the FADEC won't do it. I didn't test high altitude flameout of the engine, I'm not sure at what altitude it will happen.

Mirage 2000C Engine update presentation Hello Mirage pilots, we are happy to present you the upcoming engine update for our M-2000C module. The team has been working on a new engine model that is more accurate to its real life counterpart and allows for better damage and failure simulation. This update should release on the Open Beta later this month. In this update presentation we will first introduce the reworked M53-P2 engine model and explain how it was created. We will then talk about the change it will bring to the module flight envelope and finish by presenting the other changes this update will bring. M53-P2 Engine Introduction The Snecma M-53 is an afterburning turbofan engine developed for the Dassault Mirage 2000 fighter. The M53-P2 is an improvement to the initial M53-5 improving throttle response as well as dry and wet thrust. The engine is controlled by a FADEC (full authority digital engine control) computer that translates the throttle movement into a linear and predictable engine response. The FADEC takes altitude, speed engine RPM and temperature into account to maintain optimal parameters inside the engine and ensure that maximum performance is obtained in every condition. Engine modeling The engine of the aircraft is based on a physical model that takes every engine design parameter into account. These parameters are determined using public literature, SME feedback and general knowledge of afterburning turbofan engines. Unobtainable parameters are deducted from industry standard or tuned to match known performance points of the aircraft. The engine model takes all possible external parameters (altitude, speed, temperature, humidity, pressure) into account to deliver a very detailed and as accurate as possible simulation of the engine. This model is bounded by the operational limits of the engine, namely over-speed, over-temp, flameout and wear. These limits are not “scripted”, they are probabilistic meaning that when a limit is exceeded, a failure will occur after a randomized amount of time. The farther from the limit, the sooner the failure, until it is virtually instantaneous. Engine performance The new engine maximum performance has not changed significantly with the update, but it will be more accurate in all regimes of flight and also have a more realistic behavior. The most evident change is the engine RPM that now goes up to 103% instead of 100%. This is because the aircraft was originally equipped with the less powerful M53-5 engine which would go to 100%. The biggest change in performance will come from external temperature where a 15°C increase will reduce the overall thrust by 5%. The new engine will also have an improved throttle response delay: On the ground, the time from idle to max thrust dry is 5 sec compared to 8 sec for the old model. Engine failure and damage When exceeding a limit or by undergoing battle damage, the engine will now encounter better modeled failures. These failures range from engine wear reducing performance to catastrophic blade containment failure, destroying the aircraft, and transformation of the turbine into a modern art sculpture. Emergency systems have also been improved with the addition of the emergency oil system, emergency fuel throttle, backup FADEC and afterburner cutoff. These function as they should to allow the pilot to save a damaged engine and return to base. Aircraft performances In-flight behavior In order to accommodate the new engine, the aircraft flight model has been adjusted. The new flight model will keep most of the characteristics of the old one but with an adjusted drag for both speed and AoA, pushing it closer to known performance points. The aircraft can now follow the standard break procedure, something that was not possible previously due to the drag being too high at high AoA. The aircraft can also cruise at Mach 0.95+ at altitude with an air-to-air combat load. The supersonic drag curve has also been adjusted, being the highest in transonic then reducing once out of this zone. Ground behavior We also took the time to adjust the behavior of the aircraft on the ground. The new suspension should better reflect the real aircraft like the bounciness of the front gear. The aircraft will now roll on idle on even ground and no brakes are applied, check the wheel chock before starting ! New bombs With the inclusion of the SAMP bombs into DCS, we added the SAMP-250 to the loadout of our Mirage. The SAMP-250 is a 250 kg general purpose bomb of french design that was used by the French Air Force before switching to the Mk-82 bomb. 2 versions are available, a low drag and a high drag version with a drag chute kit. It is to note that the release profile for the low drag version has not been adjusted yet and that they will always fall long. We will work on fixing that in a future patch. Other changes In addition to the engine rework, we implemented a lot of quality of life updates for the Mirage. We will list some of them : Added slats effect when deployed/retracted manually. Dissociated the 4 slats so they can be damaged independently and affect the FM. More realistic VTH field of view constraints. Added fuel dump trails. Improved exterior lights. Added customizable elastic limit (special options). Added “MISSION ACCOMPLIE” Mirage 2000C retirement celebration livery. Fixed green radio default preset to 01. Updated manual To go with the release of this update is the updated manual. The manual has been updated with the latest changes for the Mirage 2000C. It will be available in your game files (DCS Word/Mods/aircraft/M-2000C/Doc) and can also be download here : M-2000C Manual 2.2.0.pdf Conclusion With this update we again pushed the Mirage systems realism where they deserves to be. We will continue to improve the aircraft remaining systems and work on more detailed failures and damages. And to everyone flying the Mirage, thank you for your support !

As previously said, we will be adding instant action mission sometime soon for Razbam aircraft, ED and other 3rd parties need to provide instant action mission for their aircraft.

As said above, we will be creating instant action mission for our aircraft, other 3rd parties/ED need to create some for theirs. Locking this to prevent unnecessary conflicts between members.

Thanks a lot, I'll get on logging all these issues soon

South Atlantic Map early access release note Hello fellow rotary and fixed wing aircraft enthusiasts. With the imminent early access release of the South Atlantic map, we, the team, wanted to give everyone a heads-up about what you can expect from the initial early access release so you can make an informed purchase. We believe it’s important to be open and transparent regarding the current state of the project in early access and to share our goals moving towards full release and beyond. Scope of the map Since it would be our very first terrain module, the initial scope of the map was to represent the Falklands/Malvinas islands at the time of the Falklands conflict to have an interesting but small scale map for the team to work on. We soon realized it would be very restrictive for current aircraft in DCS to limit the map to what was available in 1982. For example the 80’s era runway at Mount Pleasant is too short to land an F16 on but we do hope to add era-specific options for the map in future for those who wish to create historically accurate scenarios. After listening to the community, the team decided to also include part of the South American content, to greatly increase the possibilities offered by the map. This scale change increased our workload by a factor of 75, which resulted in the map releasing in 2022 instead of 2020. We hope that you will agree that this decision was for the best. Including part of the South American continent really pushes the bounds of DCS maps in terms of size as this map will be the biggest yet with 3.1 Million km² total size. Technology In order to make this map as realistic as possible we decided at the early stages of the project to use satellite imagery as a base for the ground textures, providing the user with the most realistic depiction of that part of the world that we possibly could. This has provided the unique challenge of having to hand “clean” every part of the landmass to remove clouds, buildings, seasonal stitching and discoloration. This single task has taken thousands of man hours to accomplish and we’re still working on it through early access. For all Airfields and cities we have used the highest custom texture technology available within DCS currently, which is known as splatmap technology and makes use of high quality custom designed textures. In order for the map to look good at low altitude, the team needs to work on improving the mesh and textures by hand as well as adding objects like rocks, debris, additional trees and bushes. This work is very time consuming which, combined with the size of the map means we do ask for a little patience while we work on this throughout early access. Current state of the map Over the past few months we have concentrated mostly on the Falklands/Malvinas islands by, for example, refining the technology for cliff generation. We still have more work to do on the mainland, while the major cities are pretty much done with regards to placement like Rio Gallegos, Rio Grande, Ushuaia and a few others, there is still more work to be done. As you can imagine the map is absolutely massive. At this stage of the project the team feel that the map is good enough to be enjoyed by the public under EA. However, due to the fact that the mainland low altitude level of detail is still not up to the high standard we aim, more work will be done to it in a steady and timely manner during EA. The current size of the map is around 70 GB, if we had taken the decision to render all land masses using the highest quality textures, the map would have been around 250 GB. So there is a happy balance to be had with size compared to texture quality for the areas between the populated airfields, towns and cities. The team will be moving their focus from the Falkland/Malvinas Islands over to the mainland to address the issues and enhance the areas mentioned above. Assets pack Due to the requirement for further testing, we are not able to ship the assets pack with the map at this current time. The full assets pack which includes the ships will be pushed by ED at the next update. Our original thought was to delay the initial release of the map so that the assets could be included, however we feel that these are not the main focus of the map but are an enhancement. In addition to this we have decided to allow the first wave of the assets to be included into the core game, so this means everyone will get them for free whether they purchase the map or not. Conclusion We hope this early access release note has given everyone in the community enough information to make a well informed purchase and has explained the scope of our project. We are really proud of the work that has been done so far, everyone on the team has worked incredibly hard on this and we are committed to go as far as possible with the current software and hardware limitations to bring you the best depiction we can of this beautiful part of the world to enjoy in DCS.

The 6.5G limit is for charge FBW mode, only to be used when you are loaded with wing tanks, bombs or a non-empty center line tank. In AA mode, you get 9G and you can then override this limit it with the override elastic stop command to get 11G. My dude has some RTFM to do

Thanks, that's the tip of the iceberg regarding what we did for the engine. The upcoming engine update presentation will explain what we have done to it .

Hi, No there is no way to reset/delete them in the air. On the ground they should be deleted once the INS is turned off as they are not saved in the system, same thing for BUT 11-20. I don't think this is implemented yet.

Hello everyone, A bug snuck it's way into the today's (28/04/2022) OB update (2.7.12.23362) removing all the bindable axis of the MiG-19. Here is the fix for this issue, unzip the files in the archive in DCS World\mods\aircraft\MiG-19P\Input and replace the previous files. We are very sorry that this bug made it to the OB and we will try to be more careful about these issues in the future. MiG-19P_Keybinds.rar

If you unselect RDO on the PCA the yellow tracks won't be generated anymore.
