Not a clearance.
Check your location, inspect source records, and see what still needs verification.
01 / YOUR OPERATION
Set your position
GPS is requested only when tapped. No background tracking or saved location. FAA queries send your search area to FAA-hosted ArcGIS services. Map tiles send the viewed area to USGS; no location is stored by this app.
No position selected. Nothing has been checked.
02 / SOURCE HEALTH
Know what you’re seeing
Refresh position and data separately. A successful download is not proof that a source is current. A five-minute timer prompts rechecking; it is not an official validity period.
03 / AREA OVERVIEW
Facility grids & restrictions
Select a position to load a geographic map.
Roads, towns and coastline: USGS National Map (not FAA aviation data). FAA overlays cover the dashed search envelope only; panning does not fetch a new area. Tap a grid or boundary for original source attributes. Airspace B/C/D and surface E2/E3/E4 are shown, including overlapping altitude shelves; no automatic altitude/time applicability decision. Other airspace/restrictions and local rules are not fully represented. No map layer grants authorization.

No nearby-airport NOTAM feed is connected. The prototype does not infer notice coverage from facility grids. Check all relevant notices and operational details in official systems.
