Peter,

I've just tried with 
http://dev.x-plane.com/update/data/AptNav201208XP900.zip

(with GDAL 1.9.0)

$ ogr2ogr apt_shapes apt.dat

Warning 1: organizePolygons() received a polygon with more than 100 parts. The 
processing may be really slow.
You can skip the processing by setting METHOD=SKIP, or only make it analyze 
counter-clock wise parts by setting METHOD=ONLY_CCW if you can assume that the 
outline of holes is counter-clock wise defined

A bit verbose, but nothing to really worry about. They are just warnings, not 
errors.

And the result in a viewer looks right.
