Hi fellow wiki editors!

To help newly registered users get more familiar with the wiki (and maybe older users too) there is now a {{Welcome to the wiki}} template. Have a look at it and feel free to add it to new users discussion pages (and perhaps your own).

I have tried to keep the template short, but meaningful. /Johan G

FlightGear has the ability to produce multiple files logging properties. Both the properties and the interval between the records are user selectable.

More than one log file can be configured in the PropertyList file setting up what properties to log.

Simple example

Here is a simple example that logs the rudder and aileron positions to the file steering.csv every second or so:

<?xml version="1.0" encoding="UTF-8"?>
<PropertyList>
 <logging>
  <log>
   <filename>steering.csv</filename>
   <enabled>true</enabled>
   <interval-ms>1000</interval-ms>
   <delimiter>,</delimiter>
   <entry>
    <title>Rudder</title>
    <property>/controls/rudder</property>
   </entry>
   <entry>
    <title>Ailerons</title>
    <property>/controls/aileron</property>
   </entry>
  </log>
 </logging>
</PropertyList>

Here is some sample output:
