If unit in zone -> Activate unit X If unit out of zone -> Deactivate unit X Unit X: Set Frequency Set Transmission -> Set loop for audio file to enabled

Just to make sure, did you also set the appropriate target size according to the ship you were trying to engage?

You are limited to the weather presets available for now, it is very limited. However, you have access to the cloud file that defines how each preset looks like and you can edit it and add more. That way you would be able to achieve what you want, probably. It's located here: DCS World/config/effects/clouds.lua

Historical filter off (only applies to when selecting units in the editor)? Have you removed all of your mods and ran a repair? Can you upload an example mission?

This was changed a long, long, long time ago. https://forum.dcs.world/topic/289370-nws-button-in-flight-not-working-for-triggering-comms-menu-after-update-ob-279/#comment-4995377

If you work on the script files it won't be automatically updated as the missioneditor will save the loaded file within the mission file itself and use that one and not the one on your drives/storage. This also means that since the scripts come with the mission, it will work for everyone else aswell.

Better overview if you do it in a lua file and perhaps even bigger scripts are possible.

Have you also removed all of your mods and ran a repair? If yes, can you attach your mission?

Did you also add carts and locomotives when you placed down the train?

First, make sure you set the altimeter to the correct QNH. Then, to correct for temperature, subtract 4% of the indicated altitude per 10 degrees C below ISA, or add if the temperature is above ISA. There is a max altitude that the altimeter and HUD will show. Above it and it will just read the max number and stay there, so above a certain altitude you MUST use the external info bar if you want to know your altitude.

I'm currently not on my PC but perhaps you could check the mission settings for the arcade setting (and perhaps in the mission file itself too?)

Have you tried the default code of 1113?

Do you also give up after two attempts if you try something new but cannot do it? I have no idea what your background with aviation is, but if you have little to no experience, you will need to invest some time into training before you can fly. Best thing you can do is more training, and uploading a short track so people can give you more precise instruction. And if learning how to fly an aircraft is not enjoyable for you, perhaps you are in the wrong genre of video games...

There was an update last month or so that combined open beta and stable. Even if you still see the name "open beta", you don't have to reinstall DCS. You can ignore it and leave it as is.

Thats not a normal sound. Remove all mods and run a repair and try if it improved.

Look under axis and there you should have it. TDC = Target designator control/cursor or similar. For the exact naming, refer to the manual.

Trains in generall are full of issues and have never properly worked in DCS. It would be great if ED started to finish features before abandoning them.

You have the option to use TrackIR in the external view, so it's not mouse only.

Yes please, thank you for uploading the track. Does it always happen with an aircraft nearby or does it also happen with you completely alone in the sky? Because from your video with your description, my bet is still on wake turbulence.

Have you also already tried removing all of your mods and running a repair?

And the mission? There is also a setting that has to be enabled or disabled in the mission itself. Can you tell us what server it is with which mission or can you upload the track?

Atmospheric turbulence and wake turbulence are two different things and can be enabled seperatly in DCS. That doesn't matter. Wake turbulence stays for several minute in the air and drift only with a few knots of speed. If you crossed his flight path, you will have crossed his wake turbulence, which leads to what you recorded.

The only way to bork the saved games folder is if you have absolutely no idea what you are doing. Otherwise deconflicting mods is as simple as OvGME.

Check the wake turbulence options. If it's enabled, it's probably that.

If by warships you mean modded units, disable the historical filter (clock symbol at the bottom). If you mean any default ships, remove all of your mods and run a repair. Ships not spawning is a symptom of mod conflicts.
