rwyuse.xml

This is an edit of my original post regarding a link describing the "runwayuse.xml" file. I realize now the proper name of the file is "rwyuse.xml". The file doesn't appear to be used much in current versions of FG.

Here is the LEMG.rwyuse.xml file:
Code: Select all
<?xml version="1.0"?>
<rwyuse> <!-- Times are in UTC -->
<com> <!-- Commercial Traffic-->
<wind tail="7"
cross="20" />
<time start = "00:00"
end = "24:00"
schedule = "day"/>
</com>
<gen> <!-- General Aviation -->
<wind tail="7"
cross="20"/>
<time start="7:00"
end = "19:00"
schedule = "general"/>
</gen>
<!-- commercial schedule -->
<schedule name="day">
<takeoff>12, 13, 31, 30</takeoff>
<takeoff>13, 12, 30, 31</takeoff>
<landing>13, 12, 30, 31</landing>
<landing>12, 13, 31, 30</landing>
</schedule>
<!-- general schedule -->
<schedule name="general">
  <takeoff>13, 31</takeoff>
  <landing>13, 31</landing>
</schedule>
</rwyuse>


I see the code is generally used to specify runways to be used at certain times of the day per a schedule specified in the file. It also breaks down runway use by "commercial" or "general aviation" aircraft and "takeoff" and "landing" runways. I am not understanding the use of the following:
Code: Select all
<wind tail="7"
cross="20"/>

In most rwyuse.xml files, the same values as listed above are used. Only a couple use different "wind tail" and "cross" values. What does this part of the file do? Can it be used to specify that if the wind is coming from a certain range of direction that a certain runway be used? Or are wind factors for runway assignment handled differently in currect versions of FG?
