RealTraffic 1.0 beta and updated Foreflight 2.0 beta

[kiek]

Hi Balt,
Thx for the information. I'm running 3.0.2 but no traffic. Will mail you if it is still the same in two days.
Cheers,
Nico

Hi Balt.

I'm glad to tell you it's alive again.

It looks to me it had something to do with the sequence in which I pushed  the buttons in the settings window. Note that I'm experimenting with using the Foreflight stream to create liveries in P3D, so I checked Broadcast to Foreflight and after that I had to check and uncheck some of the three checkboxes in the last line to get it alive.Don't know if this is useful to you, but just to let you know.

Regards,
Nico

Hi Balt,

I'm using the 'Broadcast traffic to ForeFlight' in order to generate the right liveries in P3D.
Today I found something strange:
It looks to me that the airborn field is always 1, so as well on the ground as in the air.
Here a few lines of ground traffic:

XTRAFFICPSX,124451586,52.3062,4.7734,0,0,1,14,10,BAW430(A321)

and here a few lines of Air TFC:

Could you have a look at it?

Hi Balt,

Here another observation:

According to this specification https://www.foreflight.com/support/network-gps/ the Altitude should be above MSL.
However, I've noticed that in your Foreflight stream this is not the case. When aircraft land at Frankfurt for instance, the altitude counts down to 0, while EDDF is not at sea level ... So in P3D the aircraft dives into the ground. Altitude in meters above MSL would be much nicer to have. Thats also important for keeping cruize level...

Nico

Hi Nico,

sorry I just checked this thread after replying to your email, and while I am subscribed to receive notifications when new posts appear in this topic, I don't seem to be getting them. Has anyone else not been getting notification emails?

Just as a brief response to your altimeter statement about foreflight requiring altitude in meters MSL: The altitudes broadcast in ADS-B are always in reference to standard atmosphere, i.e. 1013.2 hPa, which is flight level rather than altitude. So the altitudes you get from the ADS-B systems are only accurate if the mean sea level pressure at the location of the aircraft happens to be 1013.2 hPa. For any other pressures, the altitude will be off by roughly 30ft/hPa (showing too low if the pressure is higher and vice versa).

They are broadcast in meters (not feet or hectofeet for FL) as per their specification. You're going to have to read PSX's QNH setting and do the altitude conversion yourself (and assume that internet real weather is working and updating).

Cheers

Balt,
Thx for that explanation, next observation

They are broadcast in meters (not feet or hectofeet for FL) as per their specification.

In your broadcast I'd say that you are using feet, see the example two posts earlier.
39000 meters looks a bit too high to me ;-)

Cheers,
Nico

[Balt]

You are correct. I suspect the foreflight documentation isn't telling the truth and nothing but the truth...

Hi Balt,
Any news on this?

Another question:
Could you consider to make an option in RealTraffic such that it only broadcasts the Foreflight stream based on the PSX location, so not sending 7 aircraft to PSX?

The reason for asking is that my program generates air traffic in P3D 9 seconds behind real time. That's because I need two locations for an Aircraft in order to generate a vector. Otherwise you do not get it smooth with these long update intervals of 9 seconds. Now it's looking great, but the traffic in the PSX TCAS is 9 seconds ahead of the traffic in P3D...

While my program already is able to send traffic to PSX (doing that for VATSIM traffic), I can easily send the best 7 from RealTraffic to PSX and everything will be in sync. I also have a CDU subsystem application that gives you the details of these 7 aircraft.

Best Regards,
Nico Kaan

Hi Nico,

sorry I forgot to reply. Yes the airborne field is always 1.... I don't have a readily available way to determine that from my data sources. In ADS-B that's a standard field, but in my data sources it isn't. So there's no reliable way to determine airborne status.

I'll think about implementing to option you're asking for. I might have an hour's time later this weekend. I'll get back to you.

Great!

In the mean time here a first video of a 'bridge' in PSXseecon to P3D (work in progress)  https://www.youtube.com/watch?v=JvYJ_0ydmAg.

It shows traffic from RealTraffic in Prepar3D in the right liveries (with lights and gear control).

First a Quantas A388 landing at Heathrow, and then (at 39 seconds) a Boeing 764 Delta flight from Seattle landing at EHAM 18R, with a Boeing 772 KLM coming from Atlanta  behind.  Near the end of the movie we switch to a departing KLM 737.

In the View Aircraft menu you can see all  the airborn aircraft in range listed.

Cheers,
Nico

Very nice product! I have tried it out and love it. The only problem I have with it is that the traffic on ND keeps disappearing for around 30 seconds and then coming back for around 30 seconds all the time. Is this something normal to be seen?

[Balt]

There are several conditions that could be causing this:

- when PSX is not moving, no PSX position is received. This occurs e.g. when paused, or motion is frozen
- slow responses from the traffic servers
- intermittent traffic outages

Hi Balt,

Realtraffic worked fine for me, but after I upgraded to PSX 10.06b, I only get the message "no traffic". I tried a reinstall, choose other airports etc ... but a no avail. What could be the culprit?

Cheers,

Jos

[Balt]

Strange. Works fine for me with 10.0.6b. Just took off from the Tel Aviv - Hong Kong preset and saw a few local traffics there. Is your RealTraffic connected to PSX?

[jos d.]

yes it is connected. I positionned my aircraft at EGLL and KJFK. I just get the red "no traffic" message. My OS is w10 64 bits.

[Balt]

I can't reproduce this behaviour I'm afraid. Tried it on Windows and OS X with 10.0.6b and 3.0.2 and the just released 3.0.3 version of RealTraffic. All work for me.

Are you sure the connection to PSX is working and that PSX is not paused and the aircraft is moving?

Cheers

- Balt

[jos d.]

Hi Balt,

Yes, the connection with PSX seems to work and the simulation is not paused. However, I downloaded and installed thelatest version (the standalone one). Now, realtraffic is alive again.

Cheers,

JOs

In the last couple of days I've been having this problem as well and have now also started getting a message at startup saying there's an updated version available.
However, when I download the 'updated' version from the site I still have the same 3.0.2 version that doesn't work (anymore).
I am using the MacOS standalone version... Is the 3.0.3 version not available for my OS?
If so then I will be forced to abandon RealTraffic seeing that I am not a Windows user!

Simon

Hallo Simon,

my apologies, my automated build process broke and the OSX shared library app didn't update (the standalone version did). I've just updated the DMGs online and they are now the current version 3.0.3, please try again.

Cheers

Hallo Balt

Thanks for the quick response!
 
I've just downloaded v3.0.3 for MacOS and can confirm that my problems with 'no traffic' have now disappeared and all is working again.

Kind regards
Simon
