What it does

One-click preload of FAA obstacles, controlled airspace, protected lands, tribal lands, prisons, power lines, airports, skydive drop zones, pilot waypoints and zones, and your flight tracks.
Search a start point by city, ZIP code, FAA LID, or ICAO airport code.
Festival mode - pick a festival you've RSVP'd to on ltapzmap.com and use its exact area instead of a centre-point + radius.
Offline basemap - OSM, USGS topo, Esri / Google / Bing satellite, or MapTiler. Stitched into an OziExplorer-native calibrated .map + image pair.
UTM + lat/lon gridlines generated client-side and dropped in as .plt overlays.
Find feature in radius (server search) or in already-loaded data (local). Picks pan OziExplorer to the result via OziAPI when available.

What gets loaded into OziExplorer

Each Preload writes one merged .wpt (every waypoint), one merged .plt (every line and polygon), a single merged .gpx (the same data in GPX form), and - if you ticked offline tiles - a calibrated .map + image pair for the basemap.

With OziAPI enabled in OziExplorer (Configuration → OziAPI), the app drives loading via the API - one OziExplorer window with everything in place. Without OziAPI, the app falls back to a single command-line launch with both files passed.
