Very surprised to learn that LK8000 does not grok the .sua/TNP format.
Smart soaring software should be able to handle either format without
complaint; it doesn't take much additional code.

Both formats have their drawbacks. I like the TNP format best but it
is specific to the European airspace standard.

The OpenAir format is more like a graphics drawing script, with codes
for colors and line widths and pens and brushes etc, which should be
described separately from the airspace itself. But that's another
thread.
