- Supports the initial FAA USA dataset: UAS Facility Map authorization grids and national security UAS restrictions.
- Preserves FAA authorization ceilings separately from restriction altitude bounds; a grid is never a flight authorization.
- Keeps World Airports orientation active for the partial USA coverage and retains official source attribution on local installations.
- Uses the correct regional grouping when discovering US, Canadian or Australian central sources.
