First Steps
Quick tour
After installation startup X-Plane.
In X-Plane's startup menu place yourself at a busy airport.
Maybe you want to check coverage at the web site of OpenSky Network first: You will at maximum see the same aircraft as show on their page.
No idea? Try EDDF, LSZH, KLAX, or OMDB: They have a pretty good coverage also of ground traffic. To make things perfect choose a gate or ramp position for your own aircraft rather than a runway...you don't want to be in the way of starting live traffic, do you?
Start your "flight"!
Live Traffic should welcome you with a short message on the screen. Message output is generally in the top right corner.
If you run XSquawkBox, X-IvAp or any other multiplayer client in parallel please read about that now.
Switch to Tower View [Shift-5] and maybe from there even to Free-Camera [c] to roam around and watch.
As soon as it says "...displaying 1..." there really is a new aircraft in the air...somewhere.
Go to the menu and select Plugins > LiveTraffic > Status / Information... to see a list of aircraft. They are not all visible. Select Only displayed a/c to reduce the list to actually visible aircraft.
Give LiveTraffic one or two minutes time to collect and buffer data and stabilize derived flight paths, then just enjoy watching traffic for a while.
If you activate the AUTO option in that A/C Information window, then it will show you information on the nearest aircraft in your camera direction. Very useful when just looking around or our of a cockpit window.
In the Status window open the 3rd tab labelled "Status / About": It briefly summarizes a lot of information on how LiveTraffic is doing. In case of problems start here!
Open X-Plane's internal map: All of LiveTraffic's planes appear there, too.
And when you find or make that gap - take off yourself and chase the others...or just link into the chain of approaching aircraft and be a good chain link. Check your TCAS...it might work!
