Thanks, yes, I will refine the errors - this is just the first cut of a rewrite
xacars backend code changed since their update. Did you update xacars? When I tested it, it seemed ok.
The airway db I changed a column name, so did you drop that table before the update? Try dropping the table again (delete the airways table), and run the update again, see if there are entries. There should be about 8000 entries in that table.
Also, check the debug logs for errors.
