I would certainly be interested in a way to get a list of nearest
airports from nasal, as I need it for my current overhaul of the
animated jetway project.

At the moment, I'm getting a list of airports within a 50-nm radius
using the search function of the GPS by setting properties
in /instrumentation/gps/scratch. However, this causes the GPS search to
reset itself every 30 seconds- or randomly from a user's perspective.
Not very ideal. I could work around this by resetting the scratch
properties back to their original values and rerunning the search, but
that wouldn't restore the original results.

In theory, I could apply the same technique to create a moving map that
shows airports and navaids, but that would cause the search to reset
itself every 2 seconds! Clearly a usability drawback. Perhaps
lengthening the update period to 30 or so seconds would make this
slightly more practical.
