Settings - Advanced
The "Advanced" section of the Settings dialog: Logging, Aircraft selection, and UI
Settings are available from X-Plane's menu: Plugin > LiveTraffic > Settings.... In the "Advanced" section you can tweak some rather internal parameters of LiveTraffic, which you should definitely understand before changing.


Settings > Advanced > Logging
Log.txt logging Level
Amount of information written to X-Plane's log file Log.txt: Debug is most, Fatal is least amount of information. Less than Error is not recommended.
In case you can reproduce an error or weird behaviour then please set this to Debug before your reproduce once more. Then create a support request and attach the resulting log file.
Message Area
Level of messages shown in the message area in the top right corner. Fatal shows least, Info most messages.
Only selected messages appear there at all. With this setting you can further reduce the number of messages appearing. Less than Warning is not recommended, however.
Max Message List Len
Number of messages kept for display in the Messages List

Aircraft Selection

Settings > Advanced > Aircraft Selection
Max number of aircrafts
Maximum number of aircrafts to display.
Search distance
Distance in nautical miles around current viewing position which is scanned for live flight data.
Snap to Taxiways
Aircraft positions will be updated to the closest taxiway or runway centerline, if there is such a taxiway/runway in a maximum distance of this many meters.
The feature is completely switched off (and scenery no longer read) if set to 0. See here for more details on taxiway snapping.
Live data refresh
Number of seconds to wait between two queries for live flight data.
Note that data for any one aircraft does not update continuously. Querying data more often will not have much of an effect.
If enlarging this value, then the Buffering Period and the A/c outdated period might automatically be enlarged, too, if necessary.
Buffering Period
Seconds to buffer before displaying aircrafts. This serves as the look-ahead buffer for LiveTraffics data cleansing and take off/landing prediction and is equivalent to the time lag between LiveTraffic's aircraft display and reality. Must be greater or equal to the Live data refresh period. See an FAQ for more background.
A/c outdated period
If there is no data for this number of seconds then the aircraft is removed from display.
This setting must be greater than twice the Live data refresh period, otherwise aircrafts have no chance of collecting enough data for display.
Also see a FAQ on that.
Network timeout
Number of seconds a network request is allowed to take before considering it failed.
Note that OpenSky is known to sometimes respond sluggishly, taking up to 60s. Hence values below 60s are not recommended if using OpenSky for tracking data.


Settings > Advanced > Export
These settings control temporary (read: not saved to the configuration file) export of all received tracking data into a file named <X-Plane>/Output/LTExportFD - <timestamp>.csv. This export file can be used for analysis or for feeding back into LiveTraffic.
Export Tracking Data
Export each received tracking data record from all active channels.
Export User Aircraft
Export user's aircraft position every 15 seconds. The user's aircraft will be recorded with call sign "USER" to be able to identify it when fed back into LiveTraffic.
Both export options can be on at the same time.
Export: Normalize Time
The timestamp logged into the export file usually is a Unix-like timestamp telling the time when the position record was valid. With this option enabled the timestamp will instead be number of seconds since start of export. This might simplify analysis and merging several files.

User Interface

Settings > Advanced > User Interface
Transparent Settings
Display this Settings window as a transparent window just like the Aircraft Information Window. Changes to this toggle require you to re-open the Settings.
Font Scaling
Opacity of both the Aircraft Information Window (where this same value can be change, too) and a transparent Settings window.
100% means full black background, 0% means no background at all.
The [Reset to Defaults...] button allows you, after a confirmation prompt, to reset all Advanced Settings to their respective defaults as documented here.
