Hello devs. I wanted to ask if there is any way I could add aileron droop to an aircraft when the flaps are extended and when the aircraft is parked. I've seen project airbus and many other freeware models do it but I want to know how to add it to my own aircrafts. Any help is appreciated. Thanks in advance, x1nis.

I don't know if this is even possible with MSFS2020 and I haven't done any scenery design in years. I love flying into these small grass and dirt runways. Most of the time they are just the field with nothing else there. In real life there is usually one or two small planes setting around. Maybe a small utility shed or something. This would be a collection of items that the individual simmer could pick and choose from to add to his favorite fields. They would only show up on his computer. Thanks to all of you developers for adding so much to the enjoyment of this sim, Roy

I am running P3Dv5.2 on Windows 10-64 platform. I had VOX-ATC running previously with no problems until recently when I had to unload and reload all my programs. Now when I try to Load VOX-ATC it freezes when the Indexing window opens and I get this message: D:\System Volume Information\EfaSIDat . Can anyone let me know what that is and how I can rectify it? Any assistance would be greatly appreciated. Thank you in advance. Sincerely, Pasquale

Evening to the master race of programmers!!! Hope someone can help me out I'm looking at creating a live flight map for my website. the is linked to FSX via simconnect and displays the flight progress via a webpage.... I know this can be done as a VA I fly with has such a map, obviously they are not keen on helpping me out......... I know the language is C++ but I dont have the first clue on how to start, so I'm hoping either someone could design such a feature or help me learn how to do it......

Hello, I have a problem, I would greatly appreciate your help, I have already several days trying to investigate how to solve the problem of the upper wind of opus, when I am on the surface the wind is perfect, as I go up I lose the upper wind and it does not load me at all, I have the opus installed where it should in C: \ OpusFSI_v5, I run the program as administrator and nothing, I fly in prepardv4.5 Best regards

Hello! I have question. I made homemade button box and when i will connect device to computer i want the settings automaticlly set. Something like supported device for example: Thrustmaster Warthog. How to do it? Best regards Kacper

Create your First Flying Object, Put on a 3D PBR Texture, and Export to MSFS2020 in just 20 minutes! 😃👍

tinygltf: File size mismatch : C:\MSFS SDK\Samples\Aircraft\xx\PackageSources\SimObjects\Airplanes\xx\model/GaugeAircraft_LOD00.bin, requestedBytes 419636, but got 1322580 What's going on? Thanks

Hi trying my first animation as in the screenshot. Why is it not animated? Many thanks https://share-your-photo.com/1847cce391

Hi, I'm making a simple post-processing shader for P3D v5, which requries depth input. However after drawing the depth buffer to the screen, I noticed that it's basically the grayscale version of the color buffer, instead of the expected depth buffer. Am I doing something wrong? This is the shader code: #include "Quad.sh" Texture2D<float4> srcTex; Texture2D<float> srcDepth; float4 PsSSAOMain(PsQuad vert) : SV_Target { uint2 texture_dimensions; srcDepth.GetDimensions(texture_dimensions.x, texture_dimensions.y); int3 texture_coordinates = int3(vert.texcoord * texture_dimensions, 0); float depth = srcDepth.Load(texture_coordinates…

Hi guys, I am trying to write a C# Desktop app that reads data from the sim using SimConnect. I would need to find the distance to the destination airport in the flightplan loaded. Do you guys know what variables may I read in order to get that? Can I use somehow fs9gps variables to do so?

Hihow to add a gltf model, later also other files etc. to an aircraft. In the example I've added a second mesh but doesn't build.

Hi I try to modify the MSFS CJ4 but .\fspackagetool ".\CJ4.xml" I get the above error. What to change? Thanks

I really like MSFS2020 flight dynamics engine which is simple, accurate and flexible. PC-6 flight model was created and tested in accordance with the real charts and everything perfectly match! It is a way better and easier than tuning flight model using Plane Maker. 😃

I would like to motorize my homemade Throttle-quadrant. In order to find out when the A/T should be disconnected from the thrustlevers I want to make use of the states of the FMA (Flight Mode Annunciator) as shown in tle most-left box of the PFD/ND. To my understanding, the A/T should be disconnected when the mode is eighter [ARM] or [THR HLD], or when the A/T is off. Does anyone know how to read the values [ARM] or [THR HLD] of the FMA? I use P3Dv4.5 and PMDG738NGX BR/ Niek van der Corput

Hi, I didn't see Aerosoft's ENGM listed in my list of apps, hence figured I could delete it manually. So I did. All is well but now I have red X's where the SODE gateways were. Where is the config file that controls that? Thanks, Menno

I'm trying to use the Modify Offset feature on FSRT. When I click it the window does not appear. I will click it multiple time and I notice that its trying to appear but goes away. I used the MO feature before, all the time and it would work fine. I have the most current version available. Any Idea on how to fix this?

Hi guys, i'm trying to edit the VMR file to include my VA's liveries since i've painted them and we haven't yet met the criteria for "out of the box" support, as it were. Some aircraft work perfectly with their respective sub-variations, however some will only use 2 out of the 3 and call the last one corrupt (even though 30 seconds earlier that last variation was working!). Anybody familiar with the .VMR enough to show me what i'm doing wrong? Be more than happy to share my edited vmr and the aircraft cfg's of the non-compliant aircraft... Thanks for your help in advance! (Admins please feel free to move this somewhere more appropriate if needed)

I want to download Blender2MSFS toolkit but FSDeveloper shows "Service Unavailable". Does anybody know for how long site will be down?

I am building an external app that reads the COM1/2 standby and active frequencies using SimConnect. It works fine, I get the value in BCD and I know how to decode it. The problem I have is with the new 8.33 kHz variation introduced in MSFS, which causes the last digit to be unknown. The BCD result is coded on 16 bits, for 4 decimal digits, and 5 are needed. Example: When a value of 10128 is returned, that is un binary: 0010 0111 1001 0000, it codes the following decimal digits: 2 - 7 - 9 - 0, so you can easily reconstruct the frequency: 127.90 (the trailing 1 is always there). The problem is that if you increment it, it changes to 127.905 and the result returned b…

Hi guys. I was adding my own library objects using sim director, now the problem is after placing the objects it looks fine and everything is over the ground. But when ever I ever I turn on a photoreal satellite image scenery, the objects is half sank or completely under the ground. Turning off the satellite image seems to fix the issue. But I want to use those objects over custom satellite image. So can anyone please tell whats wrong here, how can I fix the sinking issue

Hi Guys, I wonder if anyone can assist. I used to create aircraft for FSX under the name Simshed and have been thinking about getting back into the game for MSFS 2020. I appreciate that the entire process will have changed so what I'm looking for is a breakdown of what's involved now and best methods/software etc to use. Is the any guides out there anywhere?Thanks in advanceBrian Franklin
