Hi all,
Errata: It was an error in my script that showed
bad values from 2.10 apt.dat.gz... Sorry!
Using the computed center of the single runway it now
shows 46.55,7.38, which agrees with the site AND with
x-plane 10.00 ;=)) as it should...
But it does show zero displacements and stopways,
which I think is an error!
To help fix LSTZ.threshold.xml I got my script to
calculate and generate the xml from x-plane 10.00
apt.dat, which does have displacements...
<?xml version="1.0"?>
<PropertyList>
<runway>
<threshold>
<rwy>17</rwy>
<lat>46.5557604156107</lat>
<lon>7.3803149373204</lon>
<hdg-deg>172.632939426832</hdg-deg>
<displ-m>30.193488</displ-m>
<stopw-m>0</stopw-m>
</threshold>
<threshold>
<rwy>35</rwy>
<lat>46.5489074392642</lat>
<lon>7.38159918524379</lon>
<hdg-deg>352.633943174119</hdg-deg>
<displ-m>28.614624</displ-m>
<stopw-m>0</stopw-m>
</threshold>
</runway>
</PropertyList>
And a view of the runway in Google Maps shows
there are displacements on that runway...

Hope this helps to 'fix' the svn scenery data
soonest...
Regards,
Geoff.
