[...] You dont get tcas for multiplayer airplanes. 

This is exactly what I regret. It was possible in FSX /P3D, why not in MSFS? 

I should ask that question to Asobo...

I feel like we're getting closer to the day we can hear "Traffic Traffic. Descend. Descend NOW."

Which will be great for when I'm in cruise watching youtube videos on my laptop.

I am working on this, but if the sim does not provide me the expected information, it will be hard to do...

I have an answer! (I coded up the SimConnect traffic addition to the API for SU4)

The sim uses a number of differing traffic systems on top of the original FSX traffic system. My intention was to also get in AI traffic and multiplayer traffic for SU4, but I ran out of time. The systems are disparate and so all require slightly different handling to pipe into the API output, which makes stuff a bit more complicated as you don't want to spam the system with position calls that you don't need to or iterate over a bunch of junk AI plane objects every frame that are not actual things flying (stuff sitting at airports in scenery, etc).

So, it's coming, just not sure with which update.

Thanks for your answer Matt, I understand.

Basically I asked this question because I used the famous Coherent.call("GET_AIR_TRAFFIC") in my code and it returned nothing while I could see other aircraft flying around me. Is there any other way to get information about other types of traffic? Should I use SimConnect to get a comprehensive information about the traffic?

I understand there are several traffic systems that provide information that need to be filtered, but I can't understand I read no information when I see an aircraft flying just in front of me 🙂

Thanks,
Eric

[EDIT] I don't want to turn this discussion into a developer discussion that may be annoying for most of the readers here, let's continue this discussion privately 🙂

@Rocky It is about the type of traffic you were seeing. Right now the Coherent call should give you Live Traffic and SimConnect injected traffic. AI and multiplayer traffic will come later.

You could have your own solution by iterating through all SimObjects via SimConnect. But there is no good way of bringing that information back to JS right now.

Thanks for the info, this perfectly answers my question.

Now I think I know why I thought traffic was broken. This is because I was in developer mode !! I noticed that turning it on cancels the TCAS. I saw this when using the excellent PMS50 GNS-530 that replaces the GNS 530 in the C172 classic. I was seeing an aircraft symbol related to an aircraft around, which disappeared as soon as I turn the developer mode on. Good to know...

I'm not aware of any reason why turning developer mode on would remove the traffic. The JS instruments have no knowledge of whether dev mode is on nor does the JS traffic API.

Could it just have been a coincidence?

Maybe... I will do some additional tests to confirm this.

Basically I tried this after seeing this post: https://forums.flightsimulator.com/t/live-traffic-doesn-t-work-anymore/370730
I saw the question was asked to the guy knowing if he was in dev mode or not, but I realized this question is ALWAYS asked when you report a bug. So you are probably right, it might not be related, I will check again.

[EDIT] You were right, it was a coincidence, the traffic display works fine when developer mode is active (tested with the PMS50 GNS530). Sorry for the mistake.

I have just tried to use the TCAS on several aircraft, including FBW A320 Neo and the default 747. I can see some aircraft on the VFR map but they never appear on the ND. I remember it used to work, I saw some diamonds on my ND showing AI traffic around me, but today I see nothing.

Am I doing something wrong or is it a known bug in the sim?

Thanks,
Eric

 

It's working right now on the default A320.

Yes, I also noticed this.

I think my settings were not set appropriately to see the traffic, now it works fine. Sorry about that.
