IMO, we should include all these data in seperated .xml file for each

the airport, lat/longitude and a reffering xml file for that airport.
That xml file should include all the data about buildings surrounding
it, taxiways positions, parking spaces, windsocks, ATC stuff etc.
FG should read the airports.tgz file completely, but seperated xml files
on demand.
If you do that then when you try to display a list of airports in the
local area then you need to:
1. Calculate which airports *are* in the local area (because they're not
already classicied into continents/countries/whatever).
2. Read the xml file for each one, because we don't have the name in the
airport directory.
This would be SLOW.
There needs to be just enough info in the airports file to be able to
quickly provide an index. The the rest of the details can be read from a
seperate file once an airport is selected.
Yes, I thought about it more and you are correct. IOW the list of
airports file should include all the coords and search criteria in it
as well. The file can grow up quite a bit though, but we can trash
these data when in cockpit to free ram, right?
What about other flight sims? How did they solve this problem?
