1 Add data files Where can I get data?
Downloads CIFP, NASR and DOF straight from the FAA (about 65 MB) and fills in the boxes below. The FAA doesn't publish a preview DOF, so the latest one is used.
Optional: navaid.com GPX (not FAA data)
Advanced: rebuild from an edited NaviBuilder project (JSON or CSV)
Load a project you exported from the results (Download project (JSON) or Download data (CSV)) and edited. The project replaces the FAA files: it already holds every airport, navaid, fix, airspace and obstacle, so Steps 2 and 3 are skipped. Rows with errors are skipped and listed in the results and the build log.
2 Waypoint type mapping
Choose how each ARINC 424 category becomes an MGL waypoint type. Pick the IFR or VFR preset, or customize individual categories.
⚠ Keep the database light. The EFIS cannot load more than 20,000 waypoints in a 10 x 10 degree area. IFR preset is very near this maximum
3 Data merge
For each field, choose which waypoint source wins when both have it. "NASR" below means the NASR file, or the GPX file if you use GPX instead. When both NASR and GPX are loaded, GPX only fills gaps.
